Seismic Behavior of the Partially Prefabricated Laminated RC Walls Under Different Axial Ratios

The partially prefabricated laminated (RC) walls mentioned is this kind of seismic prevention element with part prefabricated concrete plate and cast in place concrete plate. 4 typical laminated walls without openings, 4 laminated walls with openings, and 1 common cast-in-place RC walls were tested under cyclic test. The seismic behaviour were analysed by the finite element software based on the test results and simulated results. The laminated walls and the common cast-in-place wall under different axial forces were simulated also. Seismic behaviour analysis indicates that the laminated walls are vulnerable to failure under high axial force compared with the cast-in-place walls, so the laminated walls are not suggested to apply in the bottom stories of the high-rise structures especially in areas vulnerable to earthquake.
