The aim of this study is to analytically assess the seismic performance of reinforced concrete (RC) columns with interlocking hoops using a novel damage index, and to provide data for developing next generation seismic design criteria. Seismic performance of RC columns is controlled by the level of confinement provided by transverse steel. Interlocking hoops are commonly used in RC columns because they can provide more effective confinement than rectangular hoops. Three RC interlocking columns were tested under a constant axial load and a cyclically reversed horizontal load. A computer program, RCAHEST (Reinforced Concrete Analysis in Higher Evaluation System Technology), is used to analyze RC structures. Novel damage indices aim to provide a means of quantifying numerically the performance level in RC columns with interlocking hoops sustained under earthquake loading. The proposed numerical method for the seismic performance assessment of interlocking columns is verified by comparison with the experimental results.

Performance Based Earthquake Engineering

The development of fragility relations is an important step in the application of performance-based earthquake engineering. Data from 69 tests were collected and reviewed to develop fragility relations for new slab-column frame construction. Damage states were defined and fragility relations were developed for reinforced and post-tensioned concrete connections, both with and without shear reinforcement. Test results were reviewed to determine the likelihood and type of repair for various damage states. Derived empirical fragilities were incorporated into the ATC-58 loss estimation software Performance Assessment Calculation Tool (PACT). Nonlinear pushover analyses were conducted on test specimens and findings were compared to test results to assess bias in common modeling approaches. Comparisons indicate that the values of median model to test ratios vary between 0.9 and 1.25 for displacements corresponding to yield and for models with column stiffness based on ASCE 41-06 median stiffness at low axial loads of 0.2 EIgross.
