Abstract
In the 2011 Tohoku Earthquake, a large number of school gymnasia suffered damage and were unable to be used as shelters. One of the most typical damage observed in steel roof gymnasia supported by RC frame were failures at the anchored connections of steel roof bearings on RC frames. In the previous paper, we have discussed on the response of cantilevered RC walls supporting steel roofs using analytical model of a damaged gymnasium in the 2011 Tohoku earthquake, and the obtained analytical results were evaluated on the observed damage. In this paper, the action of cantilevered RC walls supporting steel roofs is investigated using parametric analysis model of various school gymnasia. Based on the analytical results, a simple response evaluation method for the cantilevered frames and reaction forces at roof bearings are proposed.
