A Quantitative Method for Assessing Seismic Collapse-Resistant Capacity for RC Frame Structures

A quantitative method for evaluating the seismic collapse-resistant capacity for reinforced concrete structures is proposed. Based on the push-over analysis, pushing a building to collapse can obtain the maximum value of base shear force, corresponding to collapse critical point. The maximum shear force is divided by the total mass of the structure, and a horizontal structural acceleration called SA which represents the structure response is obtained. Then the maximum earthquake affecting coefficient can be calculated by SA and the characteristic period Tg. Finally peak ground acceleration (GA) is obtained, which can be a performance index to evaluate the seismic collapse-resistant capacity. The method is verified by two frame structure models, indicating that the method can compare the seismic collapse-resistant capacity of different buildings.
