宜蘭農工教學大樓之地震反應的分析

Abstract

地震工程上，土壤與結構互制分析的須要與日俱增，尤其臺灣地震頻繁。 國家地震工程研究中心在宜蘭農工綜合教學大樓內裝設有地震觀測儀器， 記錄地震時結構物的反應。宜蘭農工綜合教學大樓，為台灣地區常見的學 校建築型態之一。利用結構分析程式－ETABS，藉由彈性半空間模式之理 論預測探討結構物受到地震時，所引起樓層之動態反應及互制影響，本文 以台灣區域地震資料及其反應譜做為參考，以比較土壤結構互制作用與剛 性基底擾動作用對結構物樓層變位之影響。其結果可作為未來建築及結構 方面的設計參考，也可作為台灣地區類似既存建築物的耐震評估參考。 Analysis of soil-structure interaction is more important in earthquake engneering , especially，Taiwan is located in the zone of earthquakes.The teaching building of I-Lan institute of agriculture and technology is installed seismograph which records the strength ,duration and distance away of earthquakes. The teaching building is a patio-type,eigtht- floor building,and also is a common style of buildings of schools in Taiwan. Present studies use the structural analysis programs - ETABS to obtain the structural characterietics of the building.We use the elastic-half-space analysis theory to presage the influence of soil-structure interaction.In the text, we compared the analysis results to be a designing refreence of sturctures in the future.
