Structural connections are among the most essential parts in prefabricated concrete structures and good-quality design of connections is one major key to a successful prefabrication. A new horizontal wall-to-wall connection way for precast shear wall systems, which have been attempted in the field of modern residential buildings in China, is presented in this paper. An abaqus-based nonlinear finite element (FE) analysis under monotonic loading is implemented in order to understand the seismic performance of the proposed connection way of precast shear walls in comparison with that of the cast-in-place connection way. From the numerical results, it is concluded that the seismic performance of the presented connection technique, such as the deformability and the energy-dissipation capacity, is not weaker than that of its cast-in-place counterpart.

Cracking Performance

In this study, four single-story reinforced masonry shear walls (RMSWs) (two prefabricated and two cast-in-place) under reversed cyclic loading were tested to evaluate their seismic performance. The aim of the study was to evaluate the shear behavior of RMSWs with flanges at the wall ends as well as the effect of construction method. The test results showed that all specimens had a similar failure mode with diagonal cracking. However, the crack distribution was strongly influenced by the construction method. The lateral capacity of the prefabricated walls was 12% and 27% higher than that of the corresponding cast-in-place walls with respect to the rectangular and T-shaped cross sections. The prefabricated walls showed better post-cracking performance than did the cast-in-place wall. The secant stiffness of all the walls decreased rapidly to approximately 63% of the initial stiffness when the first major diagonal crack was observed. The idealized equivalent elastic-plastic system showed that the prefabricated walls had a greater displacement ductility of 3.2–4.8 than that of the cast-in-place walls with a displacement ductility value of 2.3–2.7. This proved that the vertical joints in prefabricated RMSWs enhanced the seismic performance of walls in shear capacity and ductility. In addition, the equivalent viscous damping of the specimens ranged from 0.13 to 0.26 for prefabricated and cast-in-place walls, respectively.
