- Abstract
- Reinforced concrete structural systems that have evolved over the past few decades are reviewed with respect to seismic resistance of buildings of different heights. Lateral load resisting reinforced concrete structural systems are described followed by a consideration of the criteria governing the earthquake resistant design of buildings. Possibilities of controlling ground motion input to building foundations are examined. Requirements of safety or prevention of collapse and damage control, and the design of structures to satisfy these specifications are detailed. Planning and design factors important even at the preliminary design stage are outlined. The seismic performance of reinforced concrete structural systems and the potential prediction of such performance are discussed. Prestressed and precast concrete structural systems are considered. Conclusions drawn are as follows: (1) protection of life and damage control are attainable in buildings stiffened by properly proportioned and detailed structural walls, (2) incompatibility of flexible frames with brittle infills and finishes causes high economic building damage in many earthquakes, and (3) effects of rigid elements on the seismic performance of structures renders it imperative that such elements be accounted for in the design of buildings.
