Abstract

In most design cases of buildings, design engineers assign shear walls the total seismic loads while the frames (columns and beams) take the gravity loads. It is customary to assume that cantilever model of the building structure is fully restrained against rotations at the base. It is recognized, however, that full base fixity for such large structural elements is very difficult, if not impossible, to achieve. Base rotation is a vital component of wall deformations. Therefore, it significantly affect the stiffness of cantilever walls and hence possibly their share in the lateral force resistance within elastic dual systems. The reluctance by designers to address the problem could be attributed to difficulties to estimate reliably stiffness properties of soils and to find a representative model of problems. The Dual systems of building are being studied by formulating several mathematical models covering buildings with shear walls and frames that have different heights and walls stiffness extending between high and low stiffness values relative to the total stiffness of the building. An equivalent static analysis has been carried out on these models to show the effect of shear wall-frame rocking on the wall-frame interaction in terms of internal forces and deformations. At the end of this study, the most important results and recommendations are summarized, especially the necessity of considering the interaction between frames system and shear walls system. It was proven that, the effect of shear walls rocking will be important when the stiffness of these walls is large relative to the stiffness of the building.
