Prestressing of concrete with non-metallic reinforcement is an emerging field in structural engineering, as it can significantly contribute to better exploitation of the mechanical properties of such reinforcement and behaviour of concrete structures. Non-metallic reinforcement includes fibre reinforced polymer rebars and tendons, as well as various types of textile reinforcement. Textile reinforcement is particularly challenging as a material used for prestressing because of its geometrical form and structure. Therefore a technology of chemical prestressing, where expansive cement is used to induce stresses instead of mechanical devices, comes as an alternative yet promising method for such types of reinforcement. The thesis aim was to experimentally assess the behaviour of expansive concrete members with carbon textile reinforcement. Three objectives were undertaken: 1) to prove whether chemical prestressing of concrete elements with textile reinforcement is possible, 2) to quantify the introduced prestressing forces and the influence of prestressing on serviceability limit state with a focus on cracking load, 3) to analyse the influence of chemical prestressing on aspects relevant for the design of structural members and on their performance. A feasibility study was performed to investigate the possibility of prestressing with expansive cement. Expansive strains were measured with standardized methods, as well as with distributed fibre optic sensors in specimens that were subsequently subjected to loading tests. Chemically prestressed concrete elements were tested for uniaxial tensile behaviour, in bond and flexural tests. Their behaviour was compared with this of non-prestressed ones. Measurements of expansion in time and investigations of the behaviour of tested specimens have confirmed that chemical prestressing of elements with textile reinforcement can be realized. In specimens subjected to tensile tests, concrete prestress estimated from expansion measurements corresponded very well with calculations from tensile tests results, prestressing effect was also observed in beams with steel reinforcement and large scale slab specimens with textile reinforcement. Furthermore, specimens made of expansive concrete shown a significantly higher cracking load in comparison to reference specimens made of concrete without expansive admixture. At the same time, no deterioration of concrete material properties was observed, on the contrary, compressive and tensile strength increased with an addition of expansive admixture and the modulus of elasticity remained on the same level. Finally, an overall performance index was calculated which described the performance of chemically prestressed specimens compared to the reference members.

Author(s): Arshad A. Khan, William D. Cook, and Denis Mitchell
Published By: ACI
Published Year: 1996
Size: 0.2 MB
Quality: Unspecified
Abstract: This paper presents an experimental study of early-age tensile strength (i.e., modulus of rupture) of low, medium, and high-strength concretes. In this study, low strength indicates a 28-day concrete compressive strength of 30 MPa (4300 psi), medium strength indicates a 28-day concrete compres-sive strength of 70 MPa (10,150 psi), and high strength indicates a 28-day concrete compressive strength of 100 MPa (14,500 psi). Tests on modulus of rupture specimens were carried out at frequent intervals during the first 3 days after casting to observe the influence of concrete strength. The influ ence of three different curing conditions-temperature-matched curing, sealed curing, and air-dried curing-were investigated. It was found that the gain in modulus of rupture of temperature-matched cured concrete beams is higher than that of sealed and air-dried beams. After an initial retardation period, the 70 and 100 MPa (10,150 and 14,500 psi) concretes showed a higher rate of flexural strength gain than the 30 MPa (4300 psi) concrete. It was observed that the current ACI Code expression for modu-lus of rupture overestimates the modulus of rupture for very early-age con-crete and underestimates the modulus of rupture for concrete strengths above 1.5 MPa (2175 psi). It was also found that the equation proposed by the ACI 363 Committee overestimates the modulus of rupture for all con-crete strengths and curing conditions investigated. Relationships are pro-posed to predict the modulus of rupture as a function of the concrete compressive strength. These relationships are applicable at very early ages up to an age of 91 days and account for a wide range of concrete compres-sive strengths and curing conditions.

Author(s): Compusoft Engineering
Published By: Canterbury Earthquakes Royal Commission
Published Year: February 2012
Abstract:
Compusoft Engineering Limited was engaged by StructureSmith Ltd to undertake a non-linear seismic analysis of the CTV building which collapsed as a consequence of the 22nd February 2011 Lyttelton aftershock. It is the intent that the analyses outlined within this report further enhance the understanding of the CTV performance during the 4th September 2010 Darfield earthquake, and the February 2011 Lyttelton aftershock.
The non-linear analyses outlined in this report are intended to;
• Assist with the identification of the probable sequence of failure.
• Report displacement and storey drift demands, identifying the onset and progression of damage throughout the structure.
• Monitor seismic demands on critical structural elements.
• Determine whether column hinging is expected, and if so, to what extent.
• Investigate the significance and effect of vertical accelerations on the performance of the structure.
• Investigate the variances in structural form i.e. the contribution of the masonry infill panels, and precast spandrel panels to the seismic response and performance of the structure.
The models used for all analyses have been based on building geometry, record structural drawings [1], material tests [2], along with published guidance on the hysteretic behaviour of detailing present within the CTV building.

Abstract: The appearance of distress in the form of cracking in any concrete structure is one of concern and consternation to all parties involved. It is evidence of an unfavorable stress condition and if serious enough could affect the structure’s integrity. Cracking may occur for a number of reasons but usually is the result of the interaction of several causative factors. These factors taken individually may be minor but when superimposed can result in distress. This paper presents documentation of problems that have led to cracking in post-tensioned concrete box girder bridges in Europe as well as in the United States. It discusses cracking resulting from inadequate flexural and shear capacity, thermal stress cracking, and cracking resulting from tendon curvature and tendon misalignment. Also discussed are possible retrofit measures. The intent of this paper is to bring these problems to the attention of the engineering and construction professions with the hope of precluding their recurrence.

Abstract: The objective of this study is to assess the seismic behavior of reinforced concrete bridges with skew-angled seat-type abutments through a performance-based methodology. Special attention is given to the exploration of variations in the seismic behavior of such bridges with respect to the angle of skew. Post-earthquake reconnaissance studies have reported that larger values of skew angle adversely affect performance. The idiosyncratic, "multi-phasic," behavior of skew bridges--observed during initial simulations of the present study--led to the development of a novel assessment methodology. This methodology is applied to a comprehensive database of bridges, which comprise combinations of a variety of geometric properties including: (1) number of spans, (2) number of columns per bent, (3) column-bent height, (4) span arrangement, and (5) abutment skew angle. An extensive set of nonlinear response history analyses were conducted using distinct suites of ground motions representing records for rock and soil sites, and another set that contained pronounced velocity pulses. The findings indicate that demand parameters for skew-abutment bridges--e.g., deck rotation, abutment unseating, and column drift ratio--are generally higher than those for straight bridges. Through detailed investigations of the sensitivity of various response parameters to variations in bridge geometry and ground motion characteristics, we observed that bridges with larger abutment skew angles bear a higher probability of collapse due to excessive rotations. We also found that shear keys can play a major role in abating deck rotations and thus the probability of collapse. It was further observed that the resultant peak ground velocity (PGVres) is the most efficient ground motion intensity measure (IM) for assessing skewed bridges' seismic response.

if the structures were not designed for the actual intensity of the earthquake loading. Failures of

backfill with liquefaction being the critical factor in the failures. Failures of other types of
retaining structures are relatively rare and usually involve a more complex set of conditions, such
as sloping ground either above or below the retaining structure, or both. While some failures
have been observed, there is no evidence of a systemic problem with traditional static retaining
wall design even under quite severe loading conditions. No significant damage or failures of
retaining structures occurred in the recent earthquakes such as Wenchuan earthquake in China
(2008) and, or the large subduction zone earthquakes in Chile (2010) and Japan (2011).
Therefore, this experimental and analytical study was undertaken to develop a better
understanding of the distribution and magnitude of seismic earth pressures on cantilever
retaining structures.
The experimental component of the study consists of two sets of dynamic centrifuge
model experiments. In the first experiment two model structures representing basement type
setting were used, while in the second test a U-shaped channel with cantilever sides and a simple
cantilever wall were studied. All of these structures were chosen to be representative of typical
designs. Dry medium-dense sand with relative density on the order of from 75% to 80% was
used as backfill. Results obtained from the centrifuge experiments were subsequently used to
develop and calibrate a two-dimensional, nonlinear, finite difference model built on the FLAC
platform.

Abstract: Observations of the performance of basement walls and retaining structures in recent
earthquakes show that failures of basement or deep excavation walls in earthquakes are rare even
if the structures were not designed for the actual intensity of the earthquake loading. Failures of
retaining structures are most commonly confined to waterfront structures retaining saturated
backfill with liquefaction being the critical factor in the failures. Failures of other types of
retaining structures are relatively rare and usually involve a more complex set of conditions, such
as sloping ground either above or below the retaining structure, or both. While some failures
have been observed, there is no evidence of a systemic problem with traditional static retaining
wall design even under quite severe loading conditions. No significant damage or failures of
retaining structures occurred in the recent earthquakes such as Wenchuan earthquake in China
(2008) and, or the large subduction zone earthquakes in Chile (2010) and Japan (2011).
Therefore, this experimental and analytical study was undertaken to develop a better
understanding of the distribution and magnitude of seismic earth pressures on cantilever
retaining structures.
The experimental component of the study consists of two sets of dynamic centrifuge

Abstract: Report presents the results of centrifuge model experiments and numerical analyses of seismic response of retaining structures with cohesive backfill. The experimental results show that the static and seismic earth pressures increase linearly with depth and that the resultant acts at 0.35H-0.4H, as opposed to 0.5-0.6H assumed in current engineering practice. Overall, the results also show that typical retaining walls designed with a static factor of safety of 1.5 have enough strength capacity to resist ground accelerations up to 0.4g.

Proceedings of the 10th International Conference on Mechanics and Physics of Creep, Shrinkage, and Durability of Concrete and Concrete Structures, held in Vienna, Austria, September 21-23, 2015. Sponsored by RILEM and the Engineering Mechanics Institute of ASCE.

This collection contains 187 papers invited on the basis of carefully peer-reviewed abstracts. It elucidates the intricacies of concrete, linking atomistic physics to real life civil engineering design.

Topics include: microstructures and micromechanics; multiscale creep, shrinkage, fracture, and durability properties; constitutive and numerical modeling; simulation and design of concrete structures; molecular- to lab-scale simulations and characterization of concrete; macroscopic material testing; creep and shrinkage of concrete under extreme conditions; monitoring of concrete structures and exploitation of measurement data; and creep and shrinkage properties of new cementitious materials.

Scientists from physics and engineering disciplines working on the next generation of materials will find that these papers present the state-of-the-art in concrete creep, shrinkage, and durability mechanics.
