- Abstract
- Limitations of present procedures for the design of reinforced concrete structures to withstand seismic loads are discussed. An integrated seismic design procedure (ISDP) is described which (1) allows the automatic selection and scaling of design ground motions given the earthquake magnitude, epicentral distance, and the type of overlying soil strata; (2) predicts the inelastic behavior of reinforced concrete elements when subjected to random lateral loads up to and including failure; and (3) calculates cumulative damage which can be directly correlated to observed states of damage from laboratory tests of reinforced concrete elements. Techniques for achieving the above capabilities are described and new design criteria are proposed, which are based on acceptable damage indices as functions of earthquake energy content and structural importance. The procedure is demonstrated by means of a practical example involving the seismic retrofit of a spiral reinforced bridge column.
