Evaluation Method of Impact-resistant of Dry Exterminal Panels

Abstract

This paper is compared and considered the impact-resistant of fall-weight method by JIS A 1408(Test method of bending and impact for building boards).The tested samples were dry external panels treated by JASS27.The method of this experiment is a fall-weight method and it refers the diagonal lines-fized support of JIS A 1408.The impact-energy is changed is altering weight and height and the relationship between destuction-shape of each panels and thickness of boards is observed.Moreover,the destruction statements of panels which is changed the combination between fall-height and weight which gains same impact-energy is considered.Through the result of experiment,the limited impact-energy of each panels and thickness of boards which is never destroyed are calculated.Finally the limited impact-energy line of each boards is proposed.
