Abstract

Seismic design of most structures has been made based on the concept, of seismic coefficient, for which 0.2g is commonly used. However the adequacy of the value has been subjected to constant arguments. In this study RC structure is assumed to have a square cross section with balanced reinforcement rat.io and be represented by single-degree-of-freedom (SD0F). Seismic coefficient, column height and column cross section are chosen as structural parameters, and maximum acceleration and types of waves are chosen as input wave parameters. Inelastic dynamic analysis is conducted on each set of parameters to obtain the corresponding ductility factor, which is considered as an index to structural damage. Optimum yield seismic coefficient, is determined from total cost, expectancy by introducing loss function defined as a function of ductility factor.
