空間網格結構多階段施工之研究

A Study of Space Network Structure During Construction Stage

指導教授 : 莊清鏘

摘要


空間網殼結構為空間結構的一種,通常採用階段方式建造,不同階段結構幾何、勁度、受力狀況、約束不同,力學反應和施工建造過程息息相關,傳統的力學分析方式採竣工結構一次加載分析,沒有考慮結構幾何、受力、約束的時變性,無法真實反應結構力學行為。此外,結構建造成形時最危險的狀態經常不是竣工結構,而是結構未成型的臨時狀態,為確保結構施工和完工使用的安全,應進行施工全過程的力學分析。本研究主要利用SAP2000和向量式有限元法進行空間網殼結構多階段力學分析,包括SAP2000現有施工模擬、逐層計算方法、累計計算方法和向量式有限元素法階段模擬法,同時和竣工結構一次加載方式比較,說明多階段施工和一次加載模擬結果的差異。

並列摘要


Space network structure is a type of space structure, usually built by stage. In different stage , structures geometry, stiffness, force endured and fixed is not the same. Mechanical behavior and construct process is closely bound up . In tradition mechanical analysis, it is use primary load to analyze it , without consider the change with time in structures geometry, force endured and fixed, it cannot truly response structual mechanics action. Besides that, the most dangerous status is not the completed structure; the most dangerous is when the structure is not completed. To ensure structures complete and safety, structures construct process must do the mechanical analysis. This Study is used mechanical analysis and Vector Form Intrinsic Finite Element to do the structual mechanics structure multistage of space network, Also Include SAP2000 construction during the process analysis, Stepwise Computation Method, Stored Computation Method and Vector Form Intrinsic Finite Element. This Result is compared with primary load, and show the different simulate result in Construction Phases and primary load.
