Paper Title:
Numerical Simulations on Impact Resistant Behavior of Rahmen-Slab Type RC Structures
  Abstract

In this paper, in order to gain basic knowledge of the dynamic response charac-teristics of rockfall protection galleries, falling-weight impact tests of the small size frame-slabtype reinforced concrete (RC) structures were conducted and the impact-resistant behaviorwas investigated. Also, to establish the prediction method for accumulated damage and resid-ual load-carrying capacity of the structures under repeated impact loading, a three-dimensionalelasto-plastic FE analysis method was proposed. Its applicability is discussed by comparing withthe experimental results. The following results are obtained from this study: (1) under impactloading, the structures reach the ultimate state in the punching shear-failure mode; and (2)accumulated damage of the galleries can be rationally evaluated by using the time history ofdeflection and crack patterns obtained by applying the proposed numerical analysis method.
