  5. Research paper (scientific journal) Joint seismic responce evaluation of cantilevered RC wall frames in school gymnasia with steel roofs Kazuhiko NARITA, Toru TAKEUCHI, Ryota MATSUI 日本建築学会構造系論文集 80/ 708, 273-283 2015/02 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.

  3. Oral presentation(general) SEISMIC PERFORMANCE OF SCHOOL GYMNASIA WITH STEEL ROOFS SUPPORTED BY CANTILEVERED RC WALL FRAMES The 5th Asia Confererence on Earthquake Engineering 2014/10/16 At 2011 Tohoku Earthquake, many school gymnasia suffered damages owing to not only Tsunami but the consequent shake. One of the most typical damages observed in steel roof gymnasia supported by RC frames are failures at the anchored connections of Steel roof bearings to RC frames. Such failures were observed in not only aged structure, but recently designed gymnasia, which mean that further guideline is strongly required. However, evaluation of reaction forces at these connections is not easy because of complicated response characteristics between steel roofs and cantilevered concrete walls. In this paper, the action of cantilevered RC walls supporting steel roofs is researched using an analytical model of actual damaged gymnasium in 2011 earthquake. The obtained results are evaluated on the observed damages, and response characteristics of cantilevered RC walls are discussed, followed by proposal of easy design methods for these connections.
