Numerical Analysis of Progressive Collapse Behavior of Glass Fiber Reinforced Polymer Strengthened Beam column Structures

Abstract:

Based on the experimental results of the progressive collapse behavior of beam column structures, which had different structural details or were strengthened with different measures by glass fiber reinforced polymer (GFRP) sheets, numerical analysis on the progressive collapse behavior of reinforced concrete beam column structures was implemented by using commercial finite element software MSC. Marc. The calculated results agree well with the test ones, and the simulation method is proved to be effective and practical. This paper illustrates that the progressive collapse resistance of the reinforced concrete structures can be enhanced by the GFRP sheet strengthening.
