IDARC Version 3.0: A Program for the Inelastic Damage Analysis of Reinforced Concrete Structures

摘要

The report summarizes significant modeling and program enhancements to the computer code, IDARC for inelastic damage analysis of reinforced concrete frame-wall structures. As described here, IDARC is extended to include members with tapered cross-sections and the ability to specify different envelope characteristics at each end of the member. In addition, it is now able to handle moment releases at either end of a member to model perfect hinge connections. Two new element types are available: a circular column element with circumferential arrangement of longitudinal reinforcement and spiral hoops; and an inelastic discrete spring element which can be used to model nonlinear flexible connections, or indirectly, the effect of bar pull-out and joint distortions.
