“…A numerical analysis of axially‐loaded TW3S walls using the finite element ABAQUS program was thus conducted. The ABAQUS program was chosen for the finite element analysis because of its widely‐known ability to perform nonlinear analyses for RC members . The FE‐model, which was developed in the previous study by Ho and Doh for predicting the behavior of RC walls with various support conditions under eccentric axial loading, was utilized in this research.…”

This paper presents experimental and numerical investigations on the behavior of axially‐loaded concrete walls restrained on three sides (TW3S walls). Particular emphasis was given to the influences of varying the slenderness ratio, aspect ratio, concrete strength, and eccentricity on the ultimate axial strength of TW3S walls. Because of the overly conservative nature of the code design equations and the scarcity of other available models for estimating the ultimate axial strength of TW3S walls, a more encompassing design equation has been developed. Comparisons with the test data of the current and previous studies confirmed that the proposed equation is satisfactory and reliable.

“…Load carrying capacity and ductility was observed to be inferior as compared to monolithic wall, whereas no deviation was observed in ductility and stiffness degradation of the tested walls. Figure a,b shows hysteresis curves for precast and monolithic wall respectively . The investigation concluded that the extent of damage can be reduced by increasing the depth of horizontal joint connecting beam.…”

Expeditious urbanization and population rise around the globe has fostered the need of speedy and efficient construction, thus generating immense pressure on the construction industry to introduce an efficacious construction technique. The issue can be addressed by precast technology, which is advantageous over conventional monolithic construction in regards to speed, safety, and quality control along with reduced construction cost on mass scale production. However, precast reinforced concrete (RC) buildings have experienced severe damage during the past earthquakes, attributed to seismic behavior of connections between components. Thus, it is of utmost importance to improve the joint connection details and deploy seismic resisting features in precast buildings, such as provision of precast shear walls. Researchers across the world have performed extensive experimental studies to evaluate the response of precast RC walls under lateral loading. This paper reviews on general concepts, codal provisions, precast RC wall connections, review of experimental findings, and effect of post‐tensioning on precast RC walls.

“…As for prefabricated concrete structures, prefabricated shear wall structure is a newly research hotspot, due to its convenient construction, low environmental pollution, and high quality in joints. As joints play an important role in the integrality, stability, and ductility of the prefabricated structures, they have great influence on the reliability and safety of the whole structures . From the point of previous studies and practical experience, the reliability and mechanical characteristics of joints become critical issues in the design of prefabricated reinforced concrete (RC) shear walls …”

Summary Prefabricated structure has prominent advantages such as easy control of construction quality, saving fabricating time and natural resources, and reducing environmental pollution and construction noise. The mostly used structural system in high‐rise buildings is reinforced concrete shear wall structure, which has high load capacity and lateral stiffness. Focusing on the connection of reinforcements, three T‐shaped partly prefabricated reinforced concrete shear walls and one cast‐in situ specimen in same dimensions as a control group are tested under low‐frequency cyclic loading to analyze their seismic performances in this paper. During the experiment, the axial compression ratio of specimens is fixed at 0.3, 0.4, and 0.5. Through the observation of phenomena and data analysis, hysteretic curve, skeleton curve, stiffness degradation, ductility, and load bearing capacity are compared and analyzed. The results show that partly prefabricated reinforced concrete shear wall has similar load bearing capacity with the cast in situ specimen, and it also has excellent ductility, stiffness, and energy‐dissipating capacity. The experimental results and analysis indicate that partly prefabricated reinforced concrete shear wall has outstanding seismic performances; under effective and reliable design, it can be used in building structures to play the same role as cast in situ components.
