Dynamic Response Analysis for the Frame Structure under Explosion Load

The dynamic response process for the reinforced concrete frame under different peak value of explosion load was simulated by the general finite element software SAP2000, followed by the comparative analysis on the displacement of the beams and columns under each condition. The analysis results show that the displacement of the beams and columns suffering the explosion load directly is ten times or even dozens of times more than those far away from the explosion load, which makes it clear that the explosion load influence on frame structure has a certain locality.
