中文摘要 | 隨著臺灣經濟發展,土地之使用率愈來愈高,尤其臺北盆地是臺灣建築物最緊密 之地區,若建築物之耐震安全間隔不足,於地震來臨時很可能產生碰撞,甚而崩塌,造成災 害。 本研究針對臺北盆地建築物最緊密之三種地盤 (K1、T2 及 TK2) 內之鋼筋混凝土建築 物,進行耐震分析,以評估建築物耐震所需安全間隔。本研究係以單自由度與多自由度模式 模擬建築結構,並建立單棟與雙棟建築之土壤結構動態互制分析模式,而以臺北盆地之設計 震譜製造人工地震進行分析。 研究結果顯示,T2 地盤在強震作用下及 K1 地盤在各種強度 地震作用下,均必須考慮土壤 - 結構互制效應較為安全。 同時,建築物經由土層媒介與相 鄰建築物產生之互制效應,不容忽視。 |
英文摘要 | Due to the growing economy in Taiwan, the percentage of land that has been utilized is getting higher and higher, especially in the Taipei basin. If buildings have not been kept at a safe separation distance, pounding may occur due to earthquake motion which may result in the damage or collapse of the buidings. Based on the dynamic analysis using simulated earthquakes, this study is focused on the evaluation of a proper separation distance for reinforced concrete buildings located in three zones (K1,T2, and TK2) of the Taipei hasin where the buildings are densely constructed. The analytical models are divided into two categories:one without considering the soil-structure interaction using either the single-degree-of-freedom model or the multi-degree-of-freedom model, and the other considering the soil-structure interaction using the one-building or the two-building models. The results show that, for high-intensity earthquakes in zone T2 and for all kind of earthquakes in zone K1, the effect of soil-structure interaction must be taken into account. At the same time, the effect of structure-structure interaction through soils between adjacent buildings can not be ignored. |
