摘要


摘要 針對含開腹桁式構件之鋼構架應用於大跨度建築,本文旨在探討其耐震之抵抗能力,及研究提高開腹鋼構架之抗震能力。先就該型構架模式所產生的破壞模式加以檢討,並與一般實腹H型鋼構架之耐震能力作比較,探討兩者所產生的抗震差異,進而改善所產出的破壞機制,以達提升其耐震能力之目標。 本文主要內容乃在利用勁度分析程式及配合擬彈性分析法,進行非線性分析與比較不同型式相同跨距實例下之耐震能力。及含開腹桁式構件與H 型鋼構件之多層鋼構架之耐震能力,並與側推分析(pushover Analysis)之結果做比較。傳統非線性分析的計算較為繁複,較不易廣泛的應用,本文嘗試利用現有的線彈性分析程式,以進行非線性系統的分析,期能簡化並節省時間與資源。 經研究之後得知,含開腹桁式構件之鋼構架自重較輕,但樑深較大,可以承受較大的載重,因此可以節省材料達到經濟的效果,所以單位造價比一般鋼構架低,若能改善其耐震能力,則依理可作為主要抗彎構架,為擴大其應用於高層建築構造尚需要作深入的探討與研究。

ABSTRACT The object of this paper is to investigate the aseismic capacity of the steel rigid frame with truss type open web members by Pseudo-elastic method. Firstly, the moment curvature curve of member section have been established. Secondly, the structure will be analyzed linearly by adopting SAP2000 software, also the member force are carried out. After structure behavior into nonlinear state keep using Pseudo-elastic method, and transfer the energy which exceeding the elastic range into plastic energy. Then the nonlinear response of the frame can be simulated out. Finally, ultimate lateral force, ultimate drift, ductility and collapsed ground acceleration can be determined which are the index of estimating the structure aseismic capacity. The studies are carried out comparition for aseismic capacities between steel frames with open web members and frames with H-shape members. The study results show that steel rigid frame with open web members may be adopted in long span multiple-story under well controlled in material capacity under construction and well design in sub member arrangement for improving aseismic capacity.
