개구부를 가진 H형강 보의 보강형태에 따른 구조거동의 해석적 연구

This study conducted an analysis to identify the difference in strength before and after reinforcement of steel perforated beams using the finite element analysis program. In addition, the efficiency compared to the amount of reinforced materials and load ratio was compared as an indicator for evaluating the overall efficiency considering economic feasibility along with the increase in the strength of steel perforated beams. It can be seen that the increase in reinforcement does not necessarily increase in strength depending on the type. In the case of the same reinforcement, it was found that there was a standard for the reinforcement that was optimal for the reinforcement efficiency. The results of this study are believed to be used as basic data for the development of economic reinforcement methods through the optimization of reinforcement efficiency along with the strength reinforcement in the steel perforated beam system.
