Available in PDF, EPUB and Kindle. Book excerpt: "Precast concrete structures are not widely used in severe seismic regions due the limited knowledge of the response of these systems to reversed cyclic loading. A series of four precast concrete wall panels were tested to evaluate their response to reversed cyclic loading. These units represent the wall panels of a typical single storey precast concrete structure. In order to achieve improved ductility and energy absorption characteristic, it was found that the horizontal sliding of the wall panel along the grout-wall interface must be controlled. Due to the reversed cyclic loading and the increased wall panel participation from limiting the horizontal sliding of the wall, it was determined that shear reinforcement of each precast specimen was separated into three separate component parts, joint rotation, wall panel deformations and horizontal wall panel sliding, to compare and evaluate the seismic performance of the wall panels." --

This book was released on 2017 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unbonded post-tensioned precast concrete walls are a low-damage seismic resisting system that resist lateral loads by rocking at the wall base. This thesis addresses the uncertainty that wall-to-floor interaction can have on the seismic response and performance of buildings that use such wall systems. A computational model was developed and verified to accurately calculate the bi-directional lateral-load response of isolated post-tensioned concrete walls. The wall model was extended to represent a previously tested full scale, four storey building with post-tensioned concrete walls. The building model accurately captured the measured response of the test building that was subjected to increasing intensities of earthquake motion on a tri-directional shake-table. To accurately capture the seismic response of the building the model must represent the in-plane and out-of-plane floor behaviour, account for cracking of the floor, and represent the stiffness of the precast concrete floor units. Wall-to-floor interaction resulted in deformations that were concentrated in the link slab between the wall and adjacent precast floor unit of the test building. This deformation resulted in significant over-strength demands on the wall and column, which the dynamic loading further increased. During the 1995 Kobe earthquake motion the peak wall base shear from the building model was 110% greater compared to the same building model that did not account for wall-to-floor interaction or dynamic loading. A parametric study of the building model found that increasing the rib depth of the precast floor elements or the thickness of the floor resulted in significantly greater over-strength demands compared to the original building. The results of the parametric study confirmed that if the effects of wall-to-floor interaction are not considered as part of the design process, the inelastic mechanisms that develop when a building is subjected to an earthquake may be different than predicted and result in undesirable failure modes An innovative wall-to-floor connector that could eliminate the adverse effects of wall-to-floor interaction was experimentally subjected to the combination of vertical displacement and shear forces they would experience in a major earthquake. Within their design limits the connectors performed well and effectively isolated the floor from the walls vertical displacement while transferring shear force from the floor to the wall.

This book was released on 2016 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research in this thesis was conducted with the primary aim of advancing the current state of knowledge of unbonded Post-Tensioned (PT) precast concrete rocking walls. Emphasis was placed on systematically investigating both the static and dynamic experimental response of Single Rocking Wall (SRW) and Precast Wall with End Columns (PreWEC) systems. Using the experimental data generated, simple numerical modelling techniques were investigated and the Direct Displacement Based Design (DDBD) process was verified. The experimental programme consisted of component tests on modified energy dissipating Oconnectors and pseudo-static cyclic, snap back, and shake table testing on a selection of SRW and PreWEC systems. The unique experimental investigation into the cyclic response of an improved O-connector confirmed the suitability of the O-connector as a cost effective energy dissipater that is able to demonstrate stable hysteretic behaviour while being easy to install and replace. The focus of the wall tests was on assessing the general wall response and design, the influence of the O-connectors on the wall panel, initial stiffness and fundamental frequency, equivalent viscous damping and residual drifts from different loading types. During the wall tests only minor damage and negligible residual drifts were observed which confirmed the desirable seismic behaviour of SRW and PreWEC systems under both static and dynamic loads. An investigation was performed using a simple single degree of freedom numerical model to provide recommendations on appropriate damping schemes that are able to emulate the seismic response of SRW and PreWEC systems that were validated using the shake table test results. The numerical analyses indicated that good estimation of the seismic response could be attained when using 2% tangent stiffness proportional damping in combination with a hysteretic behaviour calibrated to the cyclic hysteresis. Lastly, an assessment of current methods used for determining the equivalent viscous damping for unbonded PT walls systems in the current DDBD framework was performed. A current method based on the weighted contribution of an unbonded PT only system and a purely dissipative system was found to produce good results when used with the proposed bilinear force-displacement idealisation based on an effective stiffness.

Book excerpt: The aim of this state-of-art report is to present current practices for use of precast and prestressed concrete in countries in seismic regions, to recommend good practice, and to discuss current developments. The report has been drafted by 30 contributors from nine different countries. This state-of-art report covers: state of the practice in various countries; advantages and disadvantages of incorporating precast reinforced and prestressed concrete in construction; lessons learned from previous earthquakes; construction concepts; design approaches; primary lateral load resisting systems (precast and prestressed concrete frame systems and structural walls including dual systems) diaphragms of precast and prestressed concrete floor units; modelling and analytical methods; gravity load resisting systems; foundations; and miscellaneous elements (shells, folded plates, stairs and architectural cladding panels). Design equations are reported where necessary, but the emphasis is on principles. Ordinary cast-in-place reinforced concrete is not considered in this report. This fib state-of-the-art report is intended to assist designers and constructors to provide safe and economical applications of structural precast concrete and at the same time to allow innovation in design and construction to continue. This Bulletin N° 27 was approved as an fib state-of-art report in autumn 2002 byfib Commission 7, Seismic design.

Available in PDF, EPUB and Kindle. Book excerpt: "A reinforced concrete ductile flexural wall requires the placement of well-detailed concentrated reinforcement at the ends of the wall. This often results in congestion in these heavily reinforced regions, resulting in labourious construction. Two flexural wall specimens, containing structural steel boundary elements, were constructed and tested under reversed cyclic loading to evaluate the performance of this new construction technique. For comparison, a third wall specimen meeting the requirements of a standard reinforced concrete ductile flexural wall was constructed and tested under reversed cyclic loading. One of the composite walls used rectangular hollow structural sections (HSS) as boundary elements which were connected to the wall by welding the transverse bars directly to both HSS elements. The second wall used steel channels connected to the wall with headed studs welded to the channels. These studs overlapped with the transverse reinforcing bars, which had headed ends. The details of these three walls were chosen such that all of the walls had approximately the same flexural capacity. The reversed cyclic responses of the three walls showed that each wall had similar hysteretic properties. Following significant yielding of the structural steel, local buckling of the steel boundary elements in the composite walls was observed. The design used for ductile flexural walls was modified to enable comparable design of reinforced walls with steel boundary elements." --
