1 Punching Shear Strength and Deformation Capacity of Fiber Reinforced Concrete Slab-Column Connections under Earthquake-Type Loading 鄭敏元 (Min-Yuan Cheng) 助理教授,台灣科技大學 民國100年03月16日(三) 土木館5樓 壹、研究起源與動機 二、Combined gravity load and uni-axial lateral displacement reversals 試體架構、材料及結果 三、Combined gravity load and bi-axial lateral SB1&SB SB3 無梁版結構 優點:簡易模板 更寬廣的空間及淨樓高 省錢 管線牽引方便無阻礙 缺點:側向勁度不足 解決方法 加預力鋼筋 連接處產生 punching shear 破壞 解決方法 Headed shear studs (2008 ACI Building Code) 並採用Fiber reinforced concrete(FRC)構件 貳、Behavior of FRC Slab-Column Connections 一、Monotonically-increased gravity-type load 試體架構、材料及結果 參、結論 一、不論是哪種試驗模型,只要採用FRC,其試驗結果皆能提升其變形容量,使得原設計規範之設計會產生瞬間崩壞的情形有顯著的改善。 二、根據試驗結果可明顯發現,ACI Building Code (2008) for headed shear stud 還有待考量並應從新評估其設計方式。
