摘要: | 鋼板混凝土複合牆是由兩面鋼面板(Faceplate)與內填混凝土(Infilled Concrete)複合而成,並由剪力釘(Shear Stud)或橫向螺桿(Tie Bar)等剪力連接器傳遞剪力,以達到良好之複合行為,早期鋼板混凝土複合牆主要運用於核能電廠結構,近幾年則陸續被應用於超高樓層結構。目前業界慣用ETABS、SAP2000等商用軟體進行結構分析,而使用此類商用軟體模擬含邊界柱鋼板混凝土複合牆非線性模型的模式尚有待研究。本研究期望能找到相對簡化但有效能估計到結構剪力強度與強度點的建模方法。
本研究主要分為以下四部份:第一部份,探討先前於前人研究中所設計的ETABS非線性模型設定尚有待優化的部分,與修正的方法。第二,根據第一部份的討論與分析成果建立XTRACT纖維模型,用於輔助設定ETABS軸力彎矩互制塑性鉸參數。第三,根據第二部份的結果,與延續第一部份所討論的結果修正前人研究中建立的非線性ETABS模型,與有限元素模型之分析結果進行比較,並討論差距與對ETABS非線性模型提出設定建議。第四,建立等值柱模型,以簡化ETABS非線性模型的設定流程,並將等值柱的分析結果與對應的有限元素模型分析之結果做比較並討論其差距,最後對等值柱模型的建立提出建議。 Steel-Plate Composite Walls (SC walls) are composed of two sheets of steel faceplates, and infill concrete. Shear connectors like shear studs or tie bars are used to transfer shear forces and ensure strong composite behavior. Initially steel-plate composite walls mainly used in constructing nuclear power plant structures, and steel-plate composite walls have found applications in constructing tall buildings in recent years. Currently, the industry uses commercial software like ETABS and SAP2000 for structural analysis. However, the simulation of the nonlinear behavior of steel-plate composite walls with boundary columns by these commercial software is still an area requiring further research. The aim is to identify more effective modeling approaches. This research aims to find simpler yet effective methods to estimate the structural shear strength and determine the strength point. It is divided into four parts: 1.Investigating and proposing improvements to the existing nonlinear ETABS model designed in a previous study. 2.Based on the discussion of first part, modifying the XTRACT fiber model established in previous research to assist in setting parameters for axial force-moment interaction plastic hinges in ETABS. 3.Rectifying the nonlinear ETABS model established in previous research based on the discussion from Part 1 and Part 2. Comparisons the analysis results with finite element model analysis results, and providing suggestions for setting ETABS nonlinear model. 4.Developing an equivalent column model to simplify the process of setting up the ETABS nonlinear model. The results from the equivalent column model analysis will be coMPared with the corresponding finite element model analysis, and suggestion for its establishment will be made. |
