Earthquakes are considered to be one of the most unpredictable and devastating natural hazards. Under these circumstances, reinforced concrete (RC) structures experience cyclic lateral load in which columns and beams certainly suffer strength degradation of shear and axial load carrying capacity in local areas such as hinging regions. As such, performance-based earthquake engineering (PBEE), i.e. pushover analysis using guidelines from FEMA 356 and ASCE 41, offers good estimate of seismic demands in a structure as it includes nonlinearity effects of the materials used. This study presents a simple hysteretic hinge model that may be used displacement-based analysis of RC plane frames. The proposed hinge model is composed of three zero-length nonlinear springs representing the axial, shear, and flexure behavior of each RC member. Nonlinear parameters of the springs were derived from geometric and material properties of RC members using the sectional analysis in Response-2000 software. Pushover analysis and response to cyclic loading were performed using Open System for Earthquake Engineering Simulation (OpenSees) program and validated by comparing the force displacement response of select forty-three RC columns available in the PEER Structural Performance Database columns and plane frame experiments of Yunfei et al. (1986) and Pampanin et al. (2002) were used to verify the proposed model. Results from these analyses show that proposed model can reasonably replicate nonlinear behavior of columns classified as shear-, shear-flexure-, and flexure-critical as well as response of RC plane frames subjected to cyclic load, therefore, may be used in performance assessment of actual RC structures.
