【Abstract】 The step-by-step numerical integration for energy and the Q-model are used in the collapse analysis of reinforced concrete frame structure.An equivalent SDOF system for representing a MDOF system can be used in the step-by step numerical integration analysis.Based on the comparison between absolute energy formulation and relative energy formulation,the equation needed to calculate the various energy quantities of relative energy formulation is developed.Making use of the double control damage criterion and index,the evaluation theory and the collapse mechanism of the structure are put forward.At the end,the kinds of special joints,which are the efficient construction measure to strengthen the collapse-resistant ability of reinforced concrete frame structures are studied.更多还原
