剪力)及搭接柱變形就能受到控制,整個搭接柱轉(zhuǎn)換結構就能正常工作。按《高規(guī)》驗算結構抗覆和整體穩(wěn)定;采用現(xiàn)澆鋼筋混凝土樓板,增強結構整體性;核心筒內(nèi)部樓板厚采用150ram,雙層雙向配筋;圍護材料選用新型輕質(zhì)材料,有利于減輕建筑自重,減小地震反應。對這類結構的關鍵部位仍須采取加強措施。高位轉(zhuǎn)換時還應注意對整體結構進行重力荷載下施工模擬計算。對平面為長矩形的建筑,落地剪力墻的數(shù)目應多于全部橫向剪力墻數(shù)目的一半。2)盡可能減少需結構轉(zhuǎn)換的豎向構件,直接落地的豎向構件越多,轉(zhuǎn)換結構越少,轉(zhuǎn)換層造成的剛度突變就越小,對結構抗震更有利。對部分框支剪力墻高層建筑結構,其轉(zhuǎn)換層的位置, 7度區(qū)不宜超過第5層。轉(zhuǎn)換大梁的受力主要受上部剪力墻剛度、剪力墻與轉(zhuǎn)換大梁的相對剛度和轉(zhuǎn)換大梁與下部支撐結構的相對剛度影響。其優(yōu)點為傳力直接、明確,傳力途徑清楚,受力性能好,構造簡單,施工較方便,設計計算較容易,是目前應用最廣的轉(zhuǎn)換層結構型式。中部則需要較小的或中等大小的室內(nèi)空間,可以在柱網(wǎng)中布置一定數(shù)量的墻體以滿足辦公用房的功能要求。關鍵詞:高層建筑;梁式轉(zhuǎn)換層;結構設計;剪壓比Designand Analysis of HighriseBuildingwith Transfer Floor StructureNanjing GaoKe Construction and development Co., Ltd Yan ShuaiAbstract:The highrise building with transfer floor structurehad plex forces,the paper is bined with a highrise mercial and residential construction example,brief highrise building with transfer floor structure, construction and design method of the transfer floor structure.
