Abstract

The paper presents a method of seismic nonlinear response analysis for RC frames designed as a bridge pier. Rigid Body Spring Model (RBSM) is adopted as a numerical model, in which material nonlinearity is introduced into springs between adjacent rigid bodies. Moment-curvature relations of RC members are derived from numerical integration on their cross sections according to nonlinear stress-strain relations of steel and concrete, and Bernoulli's assumption. Assemblage of element matrix equations through a similar procedure to an ordinary displacement method leads a fundamental equa
