摘要

A 3 storey reinforced concrete frame of 1:4 scale having brick infills was fabricated and push over test under cyclic loading with displacement control was performed. The structure was symmetric in plan and having brick infills at upper two floors. Free vibration test were also performed at different storey drifts to evaluate the frequencies and damping ratios. To observe the actual inelastic response of the structure, different nonlinear parameters like ultimate strength, ductility factor, cumulative energy dissipated and equivalent viscous damping were evaluated with the help of experimental results. These parameters are used to update the analytical results from a nonlinear analysis program SAP 2000 for reinforced concrete frame. With the updated analytical results, the nonlinear behavior and ultimate strength of the whole structure along with the vertical distribution of strorey drifts can be predicted with good reliability.
