벨트트러스를 이용한 철골모멘트골조의 하중지지능력향상에 관한 연구

Recently some building structures have collapsed because of losses of vertical load carrying capacities resulting from accidental events. In this study, limit analysis is applied to examples of collapse cases resulting from a vertical load. We also considered a change progress of load carrying capacity according to circumstances about installation of belt truss widely used in horizontal displacement control of high-rise building and then, analyzed an impact from loss of number generated by accidentally external force which has an effect on load carrying capacity of high-rise building.
