Abstract:Through an actual project study, the mechanical behavior and the stiffness composition of shear wall structure with few walls in one way (X direction) under lateral load were studied. The out-of-plane force conditions of shear walls in Y direction were studied. The different parts of the wall with out-of-plane forces were distinguished to carry out bearing capacity check under the frequent, fortification and rare earthquakes. And corresponding structure design measures were given according to the seismic performance goals. The above research shows that the walls do not yield under frequent and fortification earthquakes, but the part of the walls yield under the rare earthquake, so the problem of out-of-plane force on shear wall should be fully considered.
Keywords:structure with few walls in one-way; shear sharing ratio; out-of-plane force on shear wall; seismic design
