Influence of floor layout on seismic performance of Frame-shear wall structure

In order to study the influence of floor layout on the seismic performance of high-rise frame shear wall structure, taking the 12 storey reinforced concrete frame shear wall structure as an example, the calculation model is established by using ANSYS finite element software, and the structure under the action of earthquake is calculated and analyzed. The modal characteristics, natural frequency and maximum displacement, inter-story displacement angle and Mises equivalent stress distribution law of the structure under different floor layout schemes are obtained. The results show that the layout of 150mm-thick floor slabs for 1-6 floors and 120mm-thick floor slabs for 712 floors is the most beneficial to the overall lateral stiffness of the structure. The most dangerous section of the structure under the action of an earthquake is located at the bottom of the underlying shear wall. The calculations are carried out in accordance with the current concrete structure design code GBJ50010-2010 and the building seismic design code GB50011-2010.
