Abstract


Learning and summarizes the research of scholars on the basis of the mechanism of structural collapse . There are five main categories of structural failure criterion , but these failure criteria , the actual structural analysis , the most frequently used criteria for strength criterion and deformation criteria . Typical reinforced concrete frame structure collapsed process roughly experienced three stages : elastic stage , plastic stage , suspension stage ; If you want a comprehensive understanding of this process , the need to consider the dynamic effects of the collapse process , the impact of the collapse of the role of components contact and collision . This reference to the many countries of anti- progressive collapse design specifications , especially DOD2005 of the U.S. Department of Defense and the U.S. Public Authority GSA2003 in relevant standards . This article uses the the SAP2000 analysis software , linear static analysis and linear dynamic analysis of an existing norms in line with our 8 - story reinforced concrete structure to resist progressive collapse analysis . Judgment standard : DCR gt ; 2 structure to progressive collapse . Analysis of the structure , the four typical positions of the frame structure underlying respectively remove a column in the following order : ( 1 ) to remove the short side direction of the center of a column C1 ; ( 2 ) remove the long side direction of the center of a column A5 ; ③ remove the corner of a column A1 ; ④ remove the internal structure of a column C5 . The analysis results show that the linear dynamic analysis of the DCR values ??than linear static analysis , and in four cases the linear dynamic analysis occurs continuity collapsed . According to the results of linear dynamic analysis , the maximum DCR values ??appear in a column A1 to remove the corner corner pillars for the structure suffered the most unfavorable position of the structure after the impact load or explosion loads .
