Outline of Final Research Achievements

This research is aimed that evaluation of relationship between residual deformation angle and damage of steel building by response analysis and basic consideration of easy visual tool for showing deformation angles. By parametric analysis of steel frames, we gained followings; (1)In the frames with FA members, large residual deformation angles are occurred by input wave in 50kine and 75kine, (2)If the maximum bending moment of column base is 1.1-1.3 times to full-plastic moment of column, large residual deformation angles are occurred, (3)The residual deformation angles are varied by earthquake waves. As easy visual tool for deformation angles, luminescent paint is used. It illuminates the moment that metal recieved large strain, but the luminescent is not keep over 1-2 sec. Therefore, high-brightness visual detection system for evaluate the damage of member or structure, and the high-quantitative evaluation of luminescent are needed.
