Author(s)/Editor(s): Thomas Blanksvärd | Size: 6.5 MB | Format: PDF | Quality: Original preprint | Publisher: Luleå University of Technology | Year: 2009 | pages: 302 | ISBN: 978-91-86233-23-5

Every expedition has to have a purpose and a defined finishing line. My exploration journey as a PhD student started in September 2004. The official purpose with this mission was to investigate the suitability of using mineral-based composites for strengthening of existing concrete structures. During the last four and a half years I have learned that the unofficial purpose with this expedition was to explore my own suitability as a researcher and how to strengthen myself as an individual. The outcome of all expeditions is highly dependent on the surrounding environment, people and finances. I would therefore like to extend my personal gratitude to the following:
For the financial support I am grateful to the Swedish Road Administration, the Development Fund of the Swedish Construction Industry (SBUF), Skanska Sverige AB, the European Integrated Project “Sustainable Bridges” and Sto Scandinavia AB.
Elsa and Sven Thysell’s foundation, Maj and Hidling Brosénius Foundation, Wallenberg Fundation and Ångpanneföreningen are appreciated for scholarships enabling me to travel outside Sweden to present my research and make new friends.
Prof. Björn Täljsten, I have travelled the world under your wings and gathered knowledge not possible elsewhere. Thanks for being both a friend and firm supervisor, I hope to work with you in the future. Dr Anders Carolin, the deputy supervisor, for all on and off topic conversations and being a great mentor.
The laboratory investigations would not have been possible without the helpful members in the lab, Mr. Håkan Johansson, Civ Eng. Georg Danielsson, Mr. Lars Åström, Mr. Thomas Forsberg and Dr. Claes Fahlesson The staff at the division of Structural Engineering with its head Prof. Mats Emborg, for bringing me diversity in conversations and festivities. I would also like to send a special thought to my colleagues and friends in the research group “Innovative Materials and Structures” Gabbe, Mackan and Bennitz for all the help and support.
I mentioned that my expedition started in 2004, this was not entirely true. I have followed my father in the laboratory ever since I learned to walk. During my early missions in the division of Structural Engineering I met Prof. Lennart Elfgren who has given me insightful comments during my entire visit at the university. So thank you Dad for giving me confidence, showing me that the university was not a scary place and for all the useful and endless discussions regarding civil engineering I would also like to extend my gratitude to my mom, brother and sister for always being there, believing in me and defining me as a personWhen the academic environment became too dull, I took refuge in my band SlideShow. Thank you Poe Deprey, Foxy Black and Nicky Dollars for living the rock n roll life style with me.
Saved for last, the most important dynamic factor in my life is my wife. With your everlasting energy you bring colour and shape to the otherwise grey and square subsistence. Thank you for being you and always understanding that sometimes it requires 18h days to finish a PhD. If I need help with notations or to do NSMR strengthening, you are always first in line.
- Multiply it by infinity, take it to the depths of forever and you will still only have a glimpse of how much I love you.
This concludes my seemingly 30 year long expedition in the jungle called Luleå University of Technology. Now, it is off in to the horizon and beyond.

  • Author(s): Francis A. Oluokun, Edwin G. Burdette, and J. Harold Deatherage
  • Published By: ACI Materials Journal
  • Published Year: 1991

  • Abstract: Presents the results of an experimental investigation into the relative relationships between the elastic modulus, Poisson's ratio, and the cylinder compressive strength of concrete, especially at early ages. The applicability to concrete at early ages of some of the existing relations between these properties was also researched. Tests were performed on four different concrete mixes using conventional 6 x 12 in. concrete cylinder test specimens. Test results were obtained for ages ranging from 6 hr to 28 days. Analyses of test results show that the compressive strength and the elastic modulus are related, and an increase in one is generally similarly reflected in an increase in the other. The commonly accepted relationship that the elastic modulus of concrete is proportional to the 0.5 power of the cylinder compressive strength was found to be accurate for the elastic modulus at ages 12 hr and above for all concrete mixes investigated. Poisson's ratio was found to be insensitive to both the age and the richness of the concrete mix and did not change appreciably with compressive strength development.

  • Author(s): David Darwin, Shawn Barham, Rozalija Kozul, and Shuguang Luan
  • Published By: ACI Materials Journal
  • Published Year: 9/1/2001
  • Quality: PDF
  • Abstract: The effects of water-cementitious materials ratio, age, and aggregate type on the compressive strength, flexural strength, and fracture energy of concretes with compressive strengths ranging from 20 to 99 MPa (2900 to 14,400 psi) are studied. Concrete mixtures contain either basalt or crushed limestone aggregate with maximum sizes of 12 or 19 mm (1/2 or 3/4 in.). Mixtures are tested at ages ranging from 5 to 180 days and have water-cementitious (w/cm) ratios ranging from 0.24 to 0.50. High-strength concrete containing the higher-strength, basalt coarse aggregate attains higher compressive and flexural strengths than high-strength concrete containing limestone. The compressive and flexural strengths of medium and normal-strength concretes (fc¢ up to approximately 60 MPa [9000 psi]) are affected little by aggregate type. Concrete containing basalt yields significantly higher fracture energy than concrete containing limestone, with fracture energy governed principally by aggregate properties, independent of compressive strength, w/cm ratio, and age. Overall, as compressive strength increases, the energy stored in the material at the peak tensile load increases while the ability of the material to dissipate energy remains approximately constant. The result is increasingly brittle behavior as compressive strength increases.

Analysis of possible use of pyrolytic products as binders in asphalt mixes

  • Author(s): Lidija Avsenik, Marjan Tušar
  • Published By: GRAĐEVINAR
  • Published Year: 3/2016
  • DOI: 10.14256/JCE.1305.2015
  • Size: 284 KB
  • Quality: Scanner
  • Abstract: New binders are produced in order to reduce dependence on crude oil. This study aims to evaluate pyrolytic products and their blends with bitumen, as a possible substitution for bitumen. Bitumen of the penetration grade 70/100 was used as a matrix for the blends. Standard test were conducted in order to determine mechanical properties of the reference bitumen, pyrolytic products, and their blends.
    The results obtained during this study indicate that pyrolytic products can be used as a substitution for bitumen originating from crude oil or, in proper proportions, as an additive to that bitumen.

Abstract Current ship structure strength assessment procedures used by ship classification societies are mostly experience-based. The degradation effects of damages including fatigue, corrosion, collision and grounding on ultimate strength are seldom taken into account. Cui and Wu [1] proposed a more rational ship structure strength assessment method, First-Principle-Based Strength Assessment System (FBP-SAS), which take all damages into account. The calculation results depend on the input data and the input data depend on the aim of assessment. For newly designed ships, statistical damage data and
loading data can be used and the calculating results are reliability results. For inspecting the ship in
service, the actual damage data based on measuring can be inputted and the calculating results are the
ship structure’s actual residual ultimate strength. The purpose of this paper is to address how such a computer simulation system is developed and what problems need to be solved in order to realize practical application. Corrosion and fatigue are two main factors for strength degradation. Based on the
recent research work carried out in authors group, the ultimate strength degradation of ship structures by
corrosion and fatigue is studied in this paper and this result acts as a demonstration to the FPB-SAS
method.

Seismic design of R/C buildings with the aid of advanced analytical techniques

A seismic design procedure considering performance criteria for two distinct limit states is presented, involving analysis of a
feasible partial inelastic model of the structure using currently available powerful tools. The procedure is developed in a format
appropriate for incorporation into modern design codes, such as the Eurocode 8, and two alternatives are explored, one involving time–history analysis for appropriately scaled input motions, and a simpler one involving inelastic static (pushover) analysis. The proposed method is found to lead to better seismic performance than the standard code procedure, at least in the case of regular multistorey reinforced concrete frame structures studied herein, and in addition leads to a more economic design of transverse reinforcement in the members that develop very little inelastic behaviour even for very strong earthquakes.

Effect of floor slabs on the seismic performance of RC frames

Author: S.M Ahmed & U. Gunasekaran Anna University, Chennai, India. | Size: 1.3 MB | Format: PDF | Quality: Unspecified | Year: 2014 | pages: 13

ABSTRACT: In monolithic reinforced concrete structures, portions of the floor slabs act as flanges to the girders, thereby increasing the strength and stiffness of the girders. The question of how much the slab contributes to the lateral strength is very important for the design of structures; therefore this paper describes the effect of slabs at the joints in moment-frame structures subjected to large seismic deformations. A simple method to model a beam-column joint subassembly including the effects of both beam growth/elongation and the floor slab is introduced. The model is developed by establishing the slab crack pattern at the joint and the state of strain in the slab bars. The results of the models excluding and including slab effects are verified with the experiential test results. The joint model is incorporated in the nonlinear dynamic analyses for a five-storey and four-bay moment frame structure. Two different ground motions (El-Centro 1940 and Northridge 1994) are considered for the analyses. The results show that the cyclic inelastic bending causes the beams to increase in length and the floor slabs significantly restrain this phenomenon and cause the columns to displace by different amounts, changing the distribution of shear among the columns, and increasing the base shear of the columns. These additional forces may lead to a failure mechanism different from the anticipated one. The effect of floor slab including beam elongation effect is thus illustrated for a two dimensional moment frame building and this model works well for the lateral load analysis of frames.

Application of Nonlinear Static Procedures for Seismic Assessment of Regular RC Moment Frame Buildings

Author: Michalis Fragiadakis , Dimitrios Vamvatsikos , Mark Aschheim | Size: 1.6 MB | Format: PDF | Quality: Unspecified | pages: 27


[Image: info.png]

Abstract. The applicability of nonlinear static procedures for estimating seismic demands of typical regular RC moment-resisting frames is evaluated. This work, conducted within the framework of the ATC-76-6 project, shows the degree to which nonlinear static methods can characterize global and
local response demands vis-à-vis those determined by nonlinear dynamic analysis for three RC mo-ment frame buildings. The response quantities (engineering demand parameters) considered are peak story displacements, story drifts, story shears and floor overturning moments. The single-mode push-
over methods evaluated include the N2 and the ASCE-41 coefficient methods. Multi-modal pushover methods such as the Modal Pushover Analysis and the Consecutive Modal Pushover method also were evaluated. The results indicate that the relatively good performance of the single-mode methods observed for low-rise buildings rapidly deteriorates as the number of stories increases. The multi- mode techniques generally extend the range of applicability of pushover methods, but at the cost of additional computation and without ensuring reliability of the results.

Seismic damage on six bridges in the Veneto region (NE Italy) is estimated by means of a probabilistic approach for seismic hazard assessment and by constructing the specific fragility curve for each bridge. Construction of fragility curves is based on
various approaches from literature. With the application of the best-performing approach on the six bridges a comparative preliminary evaluation of the expected damage on the bridges was done. However, as the methodology is general, it could easily be applied to bridges of an extensive number of road networks.

Connections of steel columns to concrete foundations may be loaded by combinations of
normal force, bending moment and shear force. Shear force will primarily be transmitted by
friction between the base plate and the grout layer to the concrete foundation. If the compression force is small, or if tension force is present, as may occur in slender high rise structures like towers and masts, the friction will be small or absent. Then, the anchor bolts will be loaded by shear force and bending moment. At the Stevin Laboratory of Delft University of Technology, experimental and theoretical research has been carried out on column bases loaded by combinations of shear force and tension force.
In the paper, the main results of this research programme are summarised. The test results are presented and the analytical model that was developed to describe the load deformation
behaviour.
