Abstract:It is convenient to separate the apartment in any way in this new residential system

which named unbonded prestressed slab—special-shaped columns or shear walls residential structural system. In order to study the seismic behaviors

using SAP2000 to make Pushover analysis in a series of numerical models

which are designed based on Chinese code. Some important parameters are considered in these models

such as prestressed effect

seismic fortification intensity

horizontal force distribution and stories. Some important behaviors are discussed

such as performance points

force-displacement curves and the distribution and development of plastic hinges in structures. The research results show that the regular residential structures with not more than 12 stories can work well in the region with seismic fortification intensity of 8 degree and below.
