The purpose of this study is to estimate the response and damage of existing super high-rise buildings in Osaka against strong pulse-like ground motions. In part1, a method of modeling super high-rise non-isolated buildings and a study of response properties for Ricker wavelet are described. It is confirmed that super high-rise buildings modeled by using 1st natural period described in published structural design documents might help grasping tendency and scale of regional damage. Also, aspects of damage might change completely different by the ratio of 1st natural period and pulse period of input wave T 1 /T p and pulse displacement D p .

In order to evaluate the influence of the seismic motion on people according to the characteristics of vibration, subject experiments using a shaking table was conducted. Based on the experimental results of varying the level of vibration, evaluation curves representing the relationship between vibration characteristics and human sensitivity (anxiety, action difficulty and protective action) were determined.Additional experiments were also conducted to confirm the effect of different duration, directions, and type of motion. Then, the applicability of the evaluation curves was confirmed based on the correspondence with the past earthquake survey results.

From 2005 to 2013 among 7 districts with different vulnerability to disaster, we conducted a questionnaire survey concerning how people maintain their traditional wooden houses and compared the result with the disaster measures of the areas. Following results are obtained. 1) In all surveyed districts, seismic retrofitting had rarely been taken by the residents because of economic pressures and property inheritance issues. 2) There are familiar carpenters or trends among 7 districts, but only a few houses are maintained at fixed intervals. It is important to appropriate maintenance in order to preserve houses from earthquakes.
