摘要：

Softening of reinforced concrete sections at advanced curvatures in flexure is taken into account in collapse load analysis of frames. The analysis employs a trilinear elastic-plastic-softening approximation to real moment-curvature curves, and elastic unloading and reloading from the softening curve is assumed. Formulas for hinge length in reinforced concrete flexural members are reviewed. Elements of a stiffness matrix for elastic elements with softening portions are derived. The stiffness matrix allows extension of the capability of an existing computer program for elastic-plastic analysis to softening or hardening.
