개구부를 가진 3변고정 1변자유 장방형슬래브의 응력분포에 관한 연구 ( A Study on Stress Analysis for the Rectangular Slab Panel with Three Edges fixed and One Edge free Containing Opening )

The purpose of this study is to investigate the effect of openings on the bending moments in rectangular slab panel with three edges fixed and one edge free containing opening. For the study 177kinds of slab models are established by combining 4 variable factors. -Aspect of panel, size, location, and direction of opening The results of the analysis are as following: 1. When opening was located corner edge or center of slab, the increase of bending moment by opening was small. 2. When opening was located long edge of slab, the increase of bending moment by opening was 43%. 3. When opening was located long edge of slab, the increase of maximum deflection by opening was 86% and it was not more than L/360.(limit of Slab deflection)
