철근콘크리트 원형유공보의 비탄성해석

Abstract

Reinforced concrete (RC) beam with openings has been the subject of interest for many years in structural design. So, there have been numerous experiments to find out the capacity of the RC beam with opening. In their experiment, the size, location and shape of opening have been considered as important parameters. In spite of many experiment result, a few inelastic analysis result has been provided for RC beam with opening. In this context, we revisit the experimental results and try to provide an inelastic finite element (FE) analysis procedures and the corresponding numerical results. From the comparison between experimental and present numerical results, it is found to be that the appropriate FE analysis procedure can produce reliable numerical results close to experimental result and it can predict the capacity of RC beam with opening in efficient way.
