西安建筑科技大学硕士学位论文 西安建筑科技大学硕士学位论文 Research Into Reinforce Concrete Frame Structure Progressive Collapse Analyze Methods Specialty： Structural Engineering Name： Tong Shaoxuan Instructor：Prof. Shi Qingxuan Abstract The “Ronan Point” events happened in 1968 initiated the research of progressive collapse,in the following 40 years,as the GSA code and DOD code for the representative of progressive collapse standard constantly perfect,and widely used.The studies of progressive collapse in China started later,but with the importance of progressive collapse is more and more regarded,scholars in China has also carried out a lot of researches.However,in the current code of China,with respect to the structure of progressive collapse design,given only design principles,but has not given detail design method and design flow,therefore,the research of progressive collapse for further study not only has high academic value but also has important significance to complete the China code. The main researches of the contents are as follows: Introduced the structure of progressive collapse definition, and expound the famous progressive collapse events at home and abroad,summarizes the current research status of domestic and foreign scholars. Expound the international standard of the mainstream of progressive collapse, contrast the two American codes for progressive collapse (The GSA and DOD Code) of the design method,failure criteria,loading parameters and so on,compared to sum up the similarity and differences. Set up a 8 layers model of reinforced concrete frame structure to meet the requirements of the China code,consults the GSA standard static method were used to linear,linear dynamic method,the nonlinear static method and nonlinear dynamic method for the analysis of progressive collapse,and gives the detailed steps of analysis, comparative advantages and disadvantages of different methods. Compared to different component failure time to produce the dynamic response of the structure,
