| 中文摘要 | 依據建築技術規則之規定,21公尺以上或七層樓平面不規則建築物需進行動力分析,平面不規則之影響將反應於扭轉偶合效應,其可能造成結構分析很大的差異。本文依據單層剪式建築支承於剛性地盤及變形為線彈性之假設,採用反應譜動力分析,以計算偶合扭矩放大倍數。在不同阻尼變化下本文探討196種U形建築物,考慮扭轉偶合扭矩及忽略扭轉偶合扭矩之差異變化。本文得到阻尼比=0.05之放大倍數達3.8~7倍之結論,且求得196種建築物扭矩放大係數之關係曲線,可供設計者於U形不規則建築物規劃及初步設計時之參考。 |
| 英文摘要 | The regulation of Architecture Technology Provision requires designer to conduct dynamic analysis and design for exceed 21 meter or 7 story irregular high rised structure. In case . neglecting of torsional coupling effect may result in error analysis results. Assume single story support rigid place and linear deformation. This study mainly focuses on common irregular structure with U-shape. 192 different cases of U shape structure are studied to analysis the torsional coupling effects. The results demonstrate that the torsional coupling effect is significant. The torsion of the U shape building may enlarge 3.8~7 times under damping ratio equal to 0.05 if torsional coupling effect is considered. |
