【摘要】：隨著建筑產(chǎn)業(yè)的不斷發(fā)展,超高層建筑不斷涌現(xiàn),如何增加超高層結(jié)構(gòu)的抗側(cè)剛度、減小結(jié)構(gòu)側(cè)向位移已成為工程界關(guān)注的主要問題。近年來超高層結(jié)構(gòu)體系廣泛采用了中間核心筒與外圍框架相結(jié)合的結(jié)構(gòu)形式,通過設(shè)置伸臂桁架來協(xié)調(diào)核心筒與框架間的受力和變形。通過某項(xiàng)目介紹了伸臂桁架層轉(zhuǎn)換箱形鋼節(jié)點(diǎn)的施工方法及質(zhì)量控制措施。
[Abstract]:With the continuous development of the construction industry, super-high-rise buildings are emerging, how to increase the lateral stiffness of super-high-rise structures, Reducing lateral displacement of structures has become a major concern in engineering circles. In recent years, super-tall structure systems have widely adopted the structure form of the combination of intermediate core tube and peripheral frame. This paper introduces the construction method and quality control measures of the transfer box steel joint of the extension arm truss by setting the arm extension truss to coordinate the force and deformation between the core tube and the frame.
