Design Methods of Reinforce-concrete Frame Structure to Resist Progressive Collapse in Civil Engineering

Since the “9.11”terrorist event, the World Trade Center progressive collapsed in a flash, U.S. engineers began to really care about preventing progressive collapse in reinforced concrete buildings. When the accident has happened, the structures collapse is a serious threat to public safety. In our country, most public buildings are reinforced concrete frame structure. Comparing with shear wall structure, frame structure is more likely to collapse. Therefore, the research about progressive collapse of frame structures is very important. Some standard native and abroad such as British Standards, GSA2003, U.S. Department of Defense standard (DoD2005) and DoD2009 did researches in this text and these researches can be used for designers as reference in the project design.
