【提要】 根據(jù)板柱節(jié)點受沖切承載力的要求，現(xiàn)澆混凝土空心板柱結(jié)構(gòu)常需配置柱帽或托板。托板的配置使得等代梁剛度有所增大，為此針對配置托板的特點，根據(jù)力法基本原理，給出托板對等代梁抗彎剛度和固端彎矩的調(diào)整系數(shù)，并編制相關(guān)的表格。以某多層辦公樓為算例說明了相關(guān)公式及圖表的應(yīng)用。
【關(guān)鍵詞】 現(xiàn)澆空心樓板 板柱結(jié)構(gòu) 托板 等代框架法
Analysis Method for Cast\|in\|situ Concrete Hollow\|slab Column Structures with Drop\|panels/Zhao Yong1,Cheng Zhijun2,Wang Xiaofeng2(1 Department of Building Engineering,Tongji Univ.,Shanghai 200092,China;2 China Academy of Building Research,Beijing 100013,China)
Abstract:Drop\|panels and column caps are often disposed in cast\|in\|situ concrete hollow\|slab column structures for the requirements of punching shear resistant capacity of slab\|column joints.The drop\|panel\|equipped joints factors for adjusting the bending stiffness and fixed\|end bending moment due to the existence of drop\|panels are deduced according to the fundamental of Force Method.Related tables are also presented as references for designers.A calculation example of a multi\|floor building is given to show the applications of these formulas and tables.
Keywords:cast\|in\|situ concrete hollow\|slab; slab column structures; drop\|panel; equivalent frame method
