Wang, Y. -P.
|摘要:||本文針對清華大學人社院建築大樓之嚴重龜裂進行破壞原因鑑定，證實其為地震所致，並進而依據結構設計資料評估其耐震能力。結構電腦模擬分析採用 NSAT 軟體，進行靜載重分析及地震反應歷時分析，使用之地震記錄為中央氣象局所提供1996年7月30日新竹TCU017測站量測之真實地震。根據分析結果及建築規範之規定，檢驗構件應力及層間變位，鋼筋混凝土構件之設計強度係根據工作應力法計算。結果顯示，即使在最大地表加速度 100cm/sec2之設計地震下，所有結構構件仍在彈性範圍內，該大樓之結構設計應具適當之抗震能力。|
In this thesis, the damage assessment of College of Humanities and Social Sciences building of NITHU has been carried out in response to its severe cracking phenomenon. It has been proved that the cracking is caused. By earthquake. Assessment of the building's earthquake-resisting capacity in its current state is further performed based on structural design details. Compute simulation of the structural system have been carried out using NSAT which include static loading analysis as well as earthquakwe response analysis. The earthquake of July 30, 1996 recorded by the Central Weather Bureau at TCU017 station located in HSINCHU is used in the earthquake response analysis. The reacting member forces and the story-drifts of the structure are examined based on the calculated results and regulations of the building code. Design strength of the RC members are determined in accordance with the working stress method. The results indicate that, even under the design earthquake with peak ground acceleration of 100 cm/sec, all the structural members are still within the favorable elastic range. The structural design of this building is believed to have appropriate earthquake-resisting capability.
