Study On Multi-Layer Reinforced Concrete Structure Prevented Progressive Collapsed Performance

For building structure and lead to the destruction of the local happen for structure has collapsed, usually cause serious losses of life and property, the structure has become a continuous collapsed a serious threat to public safety the important problem of public concern has been and researchers’ attention, so the structure performance of continuous collapsed, and discuss the prevent structure in the design method of continuous collapse has important significance.In this paper the main antioxidant for reference foreign design codes and collapsed at home and abroad and experimental research of the theory research put forward, based on the construction of the classification of the continuous collapsed design, summarizes the design analysis method of continuous collapsed, and gives the this article the analytic method and analysis process. Use of the existing commercial general finite element software SAP2000suites layer of reinforced concrete frame initial damage happened resistance of the continuous performance collapsed, comparative analysis, in line with the design specification of7degrees and8degree seismic fortification reinforced concrete frame structure in considering floor and do not consider the resistance of the collapsed under the floor slab continuous performance.The analysis results show that the seismic fortification intensity is high, the initial damage surplus structure power transmission path after more than redundancy and the structure of the big with a good resistance to continuous collapsed performance; And the floor to the structure of continuous influence on the performance of the collapsed, pending further study.
