- Abstract
- A brief discussion of the general considerations involved in the earthquake-resistant design of reinforced concrete structures consisting of frames stiffened by structural walls is presented. Particular attention is given to the desirability of having most of the inelastic action occur in elements which are not critical to the overall stability of the structure. Basic requirements for the development of a practical and reliable design procedure usable by the average practising engineer are noted. The need for a comprehensive combined analytical and experimental program to lay the basis for such a development is stressed. A proposed design methodology applicable to isolated structural walls is presented briefly. With appropriate modifications, the same approach can be used for developing a design procedure for frame-wall structures. The performance of frame-wall structures during recent earthquakes has shown that such a system, when properly conceived and designed, provides an efficient solution to the requirements of life safety (i.e., no collapse) and damage control in earthquake-resistant buildings.
