| Abstract |
Recent trend in apartment buildings is to reduce interior load-bearing walls to improve spatial flexibility and for ease of remodeling. This study investigates the seismic performance and cost of apartment buildings as a function of spatial flexibility. To improve spatial flexibility the length of shear walls was gradually reduced. According to nonlinear analysis results, shear wall type apartment buildings show superb seismic performance. However for low to medium-rise apartment buildings, the combined system of shear wall and flat plate with improved spacial flexibility can also be designed to satisfy current seismic design code without difficulty. In low-rise apartment buildings wall-type structures, combined structures, and flat plate structures require similar amount of structural materials to satisfy the design loads. However as the number of story increases the structural materials, especially reinforcing steel, rapidly increase in flat plate buildings. |
