Fiber-reinforced polymer (FRP) composites are becoming increasingly popular as a material for rehabilitating aging and damaged structures. Rehabilitation of Metallic Civil Infrastructure Using Fiber-Reinforced Polymer (FRP) Composites explores the use of fiber-reinforced composites for enhancing the stability and extending the life of metallic infrastructure such as bridges.

Part I provides an overview of materials and repair, encompassing topics of joining steel to FRP composites, finite element modeling, and durability issues. Part II discusses the use of FRP composites to repair steel components, focusing on thin-walled (hollow) steel sections, steel tension members, and cracked aluminum components. Building on Part II, the third part of the book reviews the fatigue life of strengthened components. Finally, Part IV covers the use of FRP composites to rehabilitate different types of metallic infrastructure, with chapters on bridges, historical metallic structures and other types of metallic infrastructure.

Rehabilitation of Metallic Civil Infrastructure Using Fiber-Reinforced Polymer (FRP) Composites represents a standard reference for engineers and designers in infrastructure and fiber-reinforced polymer areas and manufacturers in the infrastructure industry, as well as academics and researchers in the field.

Looks at the use of FRP composites to repair components such as hollow steel sections and steel tension members
Considers ways of assessing the durability and fatigue life of components
Reviews applications of FRP to infrastructure such as steel bridges.

  Target acceleration in multimodal pushover method for R/C frames

Target acceleration in multimodal pushover method for R/C frames

Author: Ivan Balić , BSc. CE University of Split :Prof. Ante Mihanović, PhD. CE University of Split:Prof. Boris Trogrlić, PhD. CE University of Split | Size: 1.8 MB | Format: PDF | Quality: Unspecified | Year: 2013 | pages: 14

[Image: 65200797238071698140.jpg]

The procedure of searching the target ground acceleration as a measure of the lowest seismic
resistance is presented in the paper. This objective is achieved by the multimodal pushover
analysis based on the envelope principle. The pushover method founded on the linear combination
of modes (L), and on mode combinations as a square root of the sum of the squares (SRSS), is
presented. Examples of 5-storey and 9-storey R/C frames point to a highly significant influence
of higher modes. The failure ground acceleration in multimodal pushover analysis is significantly
lower, and even several times lower, compared to the single mode acceleration.

  Pushover Analysis of 4 Storey’s Reinforced Concrete Building
Posted by: TAFATNEB - 04-09-2014, 06:14 PM - Forum: Journals, Papers and Presentations - No Replies

Pushover Analysis of 4 Storey’s Reinforced Concrete Building

Author: Kavita Golghate :Vijay Baradiya: Amit Sharma | Size: 99 KB | Format: PDF | Quality: Unspecified | Publisher: International Journal of Latest Trends in Engineering and Technology (IJLTET) | Year: 2013 | pages: 5


[Image: info.png]

The earthquakes in the Indian subcontinent have led to an increase in the seismic zoning factor over many
parts of the country. Also, ductility has become an issue for all building that was designed and detailed using earlier
versions of the codes. Under such circumstances, seismic qualification of building has become extremely important.
The structural engineering profession has been using the nonlinear static procedure (NSP) or pushover analysis.
Modeling for such analysis requires the determination of the nonlinear properties of each component in the structure,
quantified by strength and deformation capacities, which depend on the modeling assumptions. Pushover analysis is
carried out for either user-defined nonlinear hinge properties or default-hinge properties, available in some
programs based on the FEMA-356 and ATC-40 guidelines. This paper aims to evaluate the zone –IV selected
reinforced concrete building to conduct the non-linear static analysis (Pushover Analysis). The pushover analysis
shows the pushover curves, capacity spectrum, plastic hinges and performance level of the building. The non-linear
static analysis gives better understanding and more accurate seismic performance of buildings of the damage or
failure element.

  Cyclic loading deterioration effect in RC moment frames in pushover analysis

Cyclic loading deterioration effect in RC moment frames in pushover analysis

Author: G. Ghodrati Amiri; B. Mohebi & S.A. Razavian Amrei | Size: 426 KB | Format: PDF | Quality: Unspecified | Publisher: Challenges, Opportunities and Solutions in Structural Engineering and Construction – Ghafoori (ed.) Β© 2010 Taylor & Francis Group, London, | Year: 2010 | pages: 6 | ISBN: 978-0-415-56809-8

The aim of this research is to investigate effect of hysteresis loops in static nonlinear analysis.
One of the inefficiencies of static nonlinear analysis is that nonlinear behavior of structural elements due to
cyclic deformations is approximately considered in the analysis, and only one quarter of a full hysteretic loop
is considered. For investigating the effect of this inefficiency in analysis results, three intermediate concrete
moment frames are selected. These models are selected from regular RC structures. The notified procedures in
FEMA-356 and proposed plastic hinges in this guideline are utilized for performing static nonlinear analysis.
A coefficient for consideration of stiffness degradation and strength deterioration is proposed by FEMA-356 in
nonlinear static analysis. This coefficient for intermediate RC moment frames is equal to unity. For calculation
of this coefficient, in this paper, the nonlinear dynamic analysis is used. Clough and Takeda Hysteretic loops
and a hysteretic loop that considers effects of severe stiffness degradation, strength deterioration and pinching
are assumed in nonlinear dynamic analysis. By comparison of results the value of this coefficient is obtained
25% more than the value proposed by FEMA-356.
