- Abstract
- The nonlinear response and failure mechanism of reinforced concrete frame-wall systems are investigated through mechanical models for both dynamic loads and static loads. Three mechanical models: a concentrated spring model, a multiple spring model, and a layered model, which take into account inelastic behavior of a reinforced concrete cantilever beam, are presented. Ten story reinforced concrete frame-wall structures are investigated. The stiffness characteristics of each constituent member are determined through one of the mechanical models by its inelastic properties or by a hysteresis model. The procedure of a load increment analysis is used for a static loading case. The equations of motion are solved by a step by step integration procedure for a dynamic loading case. Computed results are compared with experimental results.
