Abstrait:

Subway stations are important means of transportation and main targets attacked by terrorists. In order to study the subway station response and damage subjected to blast loading, numerical simulation is carried out to estimate a subway station in beijing. An “explosive-air-structure ” dynamic interactive numerical model is built for the blast dynamic analysis of subway station subjected to blast. The patterns of damage about column are compared in different charges of explosive. The damages of concrete and reforcing bar in column are discussed. Although the column near the explosive is destoried under the charge of 30kg TNT, The calculations showns that it's safe for the subway station to subject to blast loading under the charge of 30kg TNT. The local damage of column influence collapse of the station little. The dynamtic response of the structure is given to support the protection on the subway station against terrorism bombing.
