摘要

臺灣位於環太平洋地震帶上，時常受到地震災害的威脅，且由921地震勘查結果顯示部分校舍結構耐震能力堪慮，大多數校舍均有純壓連結其它建築物，其皆以單棟進行耐震能力分析，以至耐震能力不足及不符合現有耐震設計規範之要求。本文先以簡單的構架案例用不同軟體分析，研究純壓連結構架的極限承載力，載重-位移曲線，塑性鉸之形成，桿件軸力、剪力、彎矩的差異。既有校舍耐震能力評估是以結構各桿件之實際尺寸，材料性質及斷面配筋進行分析。然後模擬不同假設條件的校舍進行結構基底剪力及耐震能力比較，其研究結果可供未來校舍結構耐震能力參考。

Taiwan is located in circum-Pacific seismic belt, often under the threat of earthquake. Seismic prospecting results from the 921 earthquake, parts of the school buildings structural seismic resistant capacity are worthy of consideration. Most school buildings’ have a link to other buildings , all single buildings for seismic capacity analysis, as well as the seismic capability is not enough and do not meet the requirements of the existing seismic design specifications. First several simple frame cases were used to analyze the ultimate load of structure, load-displacement curve, formation of plastic hinge, difference between the axial force, shear force and bending moment by different computer program. Then, the base shear capacity and seismic resistant capacity of school building were compared based on the actual size of each member, material properties and section of steel reinforcement. Simulations were carried out with different assumptions. The research result can serve as a reference for school buildings’ structural seismic resistant capacity in the future.
