- Abstract
- An integrated seismic design procedure is developed which 1) allows the automatic selection and scaling of design earthquakes given the earthquake magnitude, distance from the site to the fault, and type of overlying soil strata; 2) predicts the inelastic behavior of reinforced concrete bridge columns 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 in laboratory tests of bridge columns. Techniques for achieving the above capabilities are described and new design criteria, based on acceptable damage indices as functions of earthquake magnitude, distance, and structural importance, are proposed.
