Abstract

There are special guidelines for the design of structures resistant to earthquake forces; parameters, such as the conditions and seismicity of the site, and the importance and type of structure, are the main effective factors. Consideration of these parameters in calculation and distribution of earthquake forces is significantly different in various design codes. In most of these design codes, the computation and distribution of earthquake forces are based upon the elastic structural analysis. In this approach, the real behavior of the structure is not considered and consequently it may sustain large displacements and irretrievable damage. Therefore, a new design method has been utilized in this paper, by which, the BASE SHEAR and its distribution in the height of the structure are calculated according to the plastic behavior of the structure, and which takes advantage of the energy balance. The latter is known as the PERFORMANCE BASED PLASTIC DESIGN (PBPD) method. In this method, the target drift and yield mechanism are used as performance parameters, which are based on the energy method; in addition, the equilibrium relation between the demanded work for monotonic displacement of the structure to achieve the target drift, and the internal energy obtained by the spectrum response of the equivalent SDOF for the elasto-plastic system, is used to compute the BASE SHEAR of the structure. This method has been successfully performed on MRF, CBF, EBF and special truss systems. In this paper, the PBPD method has been developed for coupled shear walls with steel link beams. The results of the PBPD method are compared with the results of the ordinary method. It is demonstrated that the PLASTIC HINGEs, the inter-story drifts and the plastic rotation of links are distributed more uniformly at the height of frames designed by the suggested method compared to those of the ordinary method.
