Study on Construction and Optimization of the Life-Saving Passage in Building Ruins Based on Numerical Simulation Method

It is a very important task to construct life-saving passage in building ruins rapidly and scientifically the process of earthquake rescue. Currently, virtual scene built train rescuers quickly scientifically. However, there are problems such as high cost, small quantity, single form. A new method constructing was proposed based on combined finite element (FE) finite-discrete (F-DE) restarted function LS-DYNA program. First, taking RC frame structure research objection, different types passages were constructed. What’s more, simple reasonable optimization rescue technologies with shortest time. Meanwhile, timing test four typical performed considering influence factors various situations. Finally, practicability validation verified through comparing actual case. The results show that restart ANSYS/LS-DYNA program can reasonably, simultaneously, optimal give route intuitively accurately. numerical simulation construction expected provide theoretical guidance for drills on-site
