Title: SEISMIC RESPONSE OF HIGH-RISE BUILDINGS CONSTRUCTED IN 1970S SUBJECTED TO LONG-PERIOD GROUND MOTIONS : Using predicted ground motions from hypothetical Nankai trough earthquakes in Kansai area
Abstract: This paper presents seismic response analysis of high -rise buildings subjected to long-period strong gmund motions predicted in Kansai area during large earthquakes along the Nankai Trough. Two steel building models , 75m and 150m 血 height and designed according ti ) common practice in the 1970s early developmental stage in Japan , are prepared to simulate seismic response under predicted ground motions obtained f 沁 m four different estimation methods and source models . Maximum response of models are investigated with respect to predicted sites , estimation methods , earthquake source , variation of magnitude of earthquakes and dynamic characteristics of sむ ructures . DemaIld of plastic de負 ) mlation for steel moment frames and moment connections during earthquakes are also revealed .
