台東消防大樓耐震評估之研究

Research on Seismic Evaluation of Tai-Tung Fire Department Building

指導教授 : 鍾立來 吳賴雲

摘要


由於台灣歷史背景的關係,現存消防建築物都相當老舊且耐震能力堪憂,且消防建築物在災難中扮演指揮中心的角色,其耐震評估與補強刻不容緩。本研究係針對台東消防大樓,一地上四層地下一層鋼筋混凝土建築物,分別進行三種耐震評估,其中包括最簡單的初步評估、斷面分析評估,還有簡易推垮分析及容量震譜法,以分別得到其最大基底剪力及破壞地表加速度。 台東消防大樓在0401台東地震中嚴重損壞,中央氣象局在台東消防大樓安裝了22個加速規以記錄其地震反應,針對其強震儀量得之數據進行分析,透過積分及基線修正以得其基底剪力及最大地表加速度,三種耐震評估與量測數據之結果進行比較。三種耐震評估中初步評估得到強度最低,斷面分析評估與簡易推垮分析次之,其結果與量測比較,顯示評估結果皆符合實際破壞情形。

並列摘要


Due to history background in Taiwan, the existing fire department buildings are mostly old and their seismic resilience ability is of concern. This research takes Tai-Tung Fire Department Building, a four-story RC structure with one story underground, as an example to conduct seismic evaluation. Three kinds of seismic evaluation methods were adopted: preliminary seismic evaluation, cross section analysis seismic evaluation, and simplified pushover. Central Weather Bureau equipped 22 seismometers to record the seismic responses of the building during earthquakes. The building was severely damaged in the April 1, 2006 Tai-Tung earthquake, and three earthquake responses were recorded prior to the demolition. The results of the seismic evaluation, the base shear and ground accelerations, were compared with the results obtained by measurement for verification. Preliminary seismic evaluation has lowest strength than cross section analysis seismic evaluation and simplified pushover. In comparison with measurement, all seismic evaluation methods matched the reality.
