Inelastic Dynamic Analysis of Flat-slab Shear Wall Building

Abstract

<p>An analytical technique for determining the inelastic responses of coupled shear wall structures is developed based on the transfer matrix technique in combination with the continuum method. It applies to nonuniform coupled shear walls resting on flexible foundations. The P-Δ effect, the possibilities of formation of the yield hinges at the ends of the connecting beams and at the bases of the walls, the effects of the rotational ductility factor of the connecting beams are also considered in this analysis.</p> <p>Based on this technique, a study is made on a two interconnected coupled shear wall model to simulate the earthquake response of a typical coupled shear wall building with different exterior and interior walls. The dynamic responses of these coupled shear walls are then compared with those obtained by conventional analysis of a single coupled shear wall to evaluate the effect of load transfer between dissimilar coupled shear walls within a building during an earthquake.</p>
