“…Seifi et al (2017) investigated the robustness of grouted connections in precast panels with a single layer of reinforcement in a series of tests, and observed reduced connection damage when the metal ducts containing the connection reinforcement were confined with transverse reinforcement. Crisafulli et al (2002) and Smith et al (2013) tested jointed precast walls (also referred to as rocking walls in the literature) featuring gap opening connections with grouted mild steel reinforcing bars across the wall-to-foundation joint. By allowing gap opening across the wall-to-foundation joint, the amount of reinforcement in the precast wall is significantly reduced as compared with monolithic walls designed for seismic resistance.…”

Precast concrete facilitates a construction method using durable and rapidly erectable prefabricated members to create costeffective and high-quality structures. In this method, the connections between the precast members as well as between the members and the foundation require special attention to ensure good seismic performance. Extensive research conducted since the 1980s has led to new precast concrete structural systems, designs, details, and techniques that are particularly suited for use in regions of high seismic hazard. This paper reviews the state of the art of these advances, including code developments and practical applications, related to four different systems: (1) moment frames; (2) structural walls; (3) floor diaphragms; and (4) bridges. It is concluded from this review that the widespread use of precast concrete in seismic regions is feasible today and that the jointed connection innovation introduced through precast research leads to improved seismic performance of building and bridge structures.dividual papers.

This research studies the lateral behavior of precast concrete wall panel applicable for a 2-story building. The specimens consist of precast and cast in-situ reinforced concrete bearing wall with 3/4 scaled. The precast wall panel was designed for gravity load only. The specific connection in this study was the welded connection between dowel bar and steel plate embedded in precast wall which was the famous one of the connection for precast bearing wall system in Thailand. The specimens are tested under reversed cyclic loadings through hydraulic actuator in laboratory. The tested results reveal that the precast concrete wall can resist maximum lateral load and show almost the same behavior as cast in-situ RC wall. The cracks of precast wall panel are concentrated around the connection while cast in-situ RC wall are flexural and shear cracks dominant 500 millimeters above the footing of wall. The superimposed technique of the element in FEM analysis is used to model the connection of precast wall. The prediction by FEM analysis for cyclic behavior, hysteretic loop and maximum load are matched with the test results for both specimens.

“…Note that for precast concrete walls, experimental studies by Crisafulli et al [22] suggest that the wf coefficient can be reduced as a result of cyclic grinding of the grout bed between the wall base [21], considering possible degradation of the grout bed under cyclic loading.…”

SUMMARYThis paper presents an analytical investigation on the seismic design and response of coupled wall structures that use unbonded post-tensioned steel coupling beams. Both monolithic cast-in-place reinforced concrete wall piers and precast concrete wall piers are considered. Steel top and seat angles are used at the coupling beam ends for energy dissipation. The seismic design of prototype structures to achieve target displacement-based performance objectives is evaluated based on nonlinear static and dynamic time history analyses. Additional recommendations are provided on shear design. Comparisons with 'conventional' structures that use embedded steel coupling beams as well as isolated walls with no coupling are provided. The results indicate that while the peak lateral displacements of unbonded post-tensioned coupled wall structures are larger than the peak displacements of structures with embedded beams, the residual displacements are significantly reduced as a result of the restoring effect of the post-tensioning steel.
