臺灣博碩士論文加值系統

鋼管混凝土柱在同尺寸下，相較於純鋼或是純混凝土柱皆有著更佳的性能。鋼管提供圍壓使得混凝土強度和韌性提升，而混凝土提供鋼管側向支撐，減低鋼管挫屈產生的機會，使得構件具有高強度、高韌性之特性。鋼結構之梁柱接頭對於台灣地震頻繁之國家，其消能能力非常重要，但又同時須兼顧經濟效應與施工性。本研究以貫穿式梁柱接頭為此次接頭之形式，進行結構大型試驗之數值模擬分析，希望能藉由數值模擬的方式提出有效之分析模型，供日後進行更多不同的研究分析。本研究使用商業數值軟體ABAQUS進行數值模擬分析。鋼管混凝土之剪力提供來自於鋼管與混凝土，因為此次鋼管之形狀為方形，其剪力傳遞行為有待確認，混凝土在反覆載重下，傳遞剪力會形成拉壓桿，因為實驗中有許多無法驗證之事項，因此希望藉由數值模型分析方式驗證。數值模擬結果可以發現，純鋼管試體在模擬上僅於Drift值4%之前能較準確模擬，相對而言，數值模型對於鋼腹板所承受剪力，無法提供類似預測準度。含有混凝土之試體，分析結果與試驗結果差強人意，甚至有分析數小時後即中斷分析之鋼管混凝土模型，未來可針對混凝土之參數與接觸面（Contact Surface）設定深入研究，或能得到更好的結果。

Concrete-Filled Steel Tube (CFST) often has a better performance than that of conventional steel or concrete columns with same size. In CFST, concrete is confined by steel and its strength and ductility are increased. On the other hand, concrete provides lateral support to prevent steel from local bucking. Thus, CFST often possesses more strength and more ductility. In Taiwan, it is important to ensure that the beam to column connection would not damage when earthquake is occurred. When designing beam to column joint, cost and constructability have to been considered.
The purpose of this study is to build an accurate numerical model for future use. In this study, simulation was performed using commercial software ABAQUS. The shear force of the concrete-filled steel tube is provided by steel and concrete. The column shape studied here is square, it is known under the cycle loading, the strut and tie mechanism will be formulated in concrete. However, the shear behavior in steel web is unclear. This study attempts to investigate such behavior through numerical simulation. Results show that the built model is able to provide a satisfy simulation for steel tube specimen (without concrete) up to 4% drift. Results of CFST simulation are relatively inaccurate. Improvement could be achieved if the concrete parameter and contact surface setting in ABAQUS are properly applied
