鋼筋混凝土槽縫墻受力行為及其工程應用

鋼筋混凝土槽縫牆在水平力作用下，藉著牆體側位移容許增大，避免如剪力牆斜裂縫出現後的嚴重剛度退化，是一種很好的吸能構材。本研究主要目的在了解槽縫牆之受力行為後，将槽縫牆模擬為一等值柱，等值柱模式是將槽縫牆一端視為彈性束制的柱元件，牆體的載重與水平位移關係（P-△曲線）以三折線模擬，分析結果與試驗值比較，相當合理。牆體分析模式建立後，將牆體置入建築結構中，以二樓含磚牆鋼筋混凝土造教室補強及十層樓RC構架辦公建築設計等案例，探討配置槽縫牆後的耐震能力提高程度，分析結果顯示配置槽縫牆的耐震能力比配置傳統剪力牆的情形佳。

The R.C. slitted wall has been recognized as an efficient energy absorption structure.It ismodelled as an equivalent column in this study.One of the boundary conditions of this columnis assumed to be elastically restrained,while the other one is clamped.The load-horizontaldisplacement relation of this column is taken to be tri-linear.The proposed model is first verifiedby comparing the analytical solutions with the experimental results,and they show satisfactoryagreement.Then the earthquake resistance capability of the slitted wall is studied by investigatingthe retrofit of a two-story framed masonry building and the response of a ten-story reinforcedconcrete structure.The results show that the earthquake resistance capability of the R.C.slittedwall is better than that of the conventional reinforced concrete shear wall.
