［提要］ RC寬扁梁轉(zhuǎn)換結(jié)構(gòu)介于梁式轉(zhuǎn)換和板式轉(zhuǎn)換之間，其布置可看作厚板在零應(yīng)力區(qū)、低應(yīng)力區(qū)掏空減薄構(gòu)成，也可看作普通轉(zhuǎn)換梁截面加寬減高構(gòu)成。通過寬扁梁轉(zhuǎn)換結(jié)構(gòu)的一個實例，分析了寬扁梁轉(zhuǎn)換結(jié)構(gòu)在重力荷載及地震作用下的受力狀況，結(jié)果表明，RC寬扁梁轉(zhuǎn)換結(jié)構(gòu)弱化了轉(zhuǎn)換梁抗彎剛度，有利于改善地震作用(特別是罕遇地震)下框支柱應(yīng)力集中，避免框支柱率先破壞，有利于實現(xiàn)強柱弱梁、強剪弱彎的抗震延性需要。RC寬扁梁轉(zhuǎn)換結(jié)構(gòu)減低了轉(zhuǎn)換梁截面高度，有利于提高建筑使用空間，降低層高，具有明顯的綜合效益。

Application of Wideflat Beam Transfer Structure in Technology Building of Shenzhen University/Gu Lei1,Fu Xueyi2,Chen Songliang2(1 China Construction (Shenzhen) Design International，Shenzhen 518033,China; 2 Architectural Design & Research Institute of Shenzhen University,Shenzhen 518060,China)
Abstract:RC wideflat beam transfer structure is between beam transfer structure and flat slab transfer structure.Wideflat beam can be regard as flat slab whittled within lower stress region or as ordinary widened and flattened beam.A case study of RC wideflat beam transfer structure is carried out, and the behavior under gravity load and earthquake action is analyzed.RC wideflat beam transfer structure weakened the rigidity of the transfer beam.Under earthquake (specially severe earthquake) action,the stress concentrate of the column which supporting transfer beam is minimized and the columns early destroying is avoided.RC wideflat beam can easily meet the ductility requirement of“strong column and weak beam” and “strong shear and weak bend”.Otherwise,RC wideflat beam reduced the transfer beams height so that the useful space is increased or the story height is shortened,the total profit is very well.
Keywords:RC wideflat beam; transfer structure; seismic design
