A Study on Fatigue Performance Evaluation of Stress Concentration of Plate Members Using Composite Material

복합재료 사용 바닥판 부재의 응력집중부에 대한 피로성능 평가에 관한 연구

Recently the compound material has interested in using the structural material as the bridge member assembly. It is the lighter material against existing construction material and has excellent durability and economy. The existing floor of bridge has its short period to repair and replace compared to other parts of the bridge with the pavement and the shoe. These deteriorations of usage and safety by aging and corrosion are needed frequent maintenance. The use of compound material as a structural member suggests solve these problems. So this thesis evaluates the static and the fatigue performance for whether there are fiber lamination direction and stress concentration section of FRP floor plate, the compound material.
