Ultimate Strength Calculation Method of RC Outer Walls Subjected To Load From Out-Of-Plane

Abstract eng:
The tsunami by the 2011 Tohoku earthquake caused extensive and severe structural damage in north-eastern Japan. The authors conducted a survey of RC structures which is built in the region in received a large tsunami in the Tohoku earthquake. RC outer wall had been the destruction of the square shape. The destruction of RC walls perforated from the out-of-plane direction by the tsunamis. In this study, the authors are suggesting the ultimate strength calculation method that will contribute from damage experience of such RC outer wall against tsunami wave design. It is considered that the ultimate strength calculation method of the outer wall subjected the tsunami loads from out-of-plane could be applied to use a bending yield line theory at the all four sides supported plate. Further, in the previous study, there were some researching results for the ultimate strength of an all four sides supported plate subjected the out-of-plane load by Dobashi et al. In these researches experimental studies have been made on the ultimate strength calculation of these floor slabs. In this paper, we compare with experimental results of Dobashi et al using a finite element analysis to confirm the validity of the finite element analysis model.
