【摘要】：裝配式防屈曲支撐的外圍約束構件主要通過高強螺栓連接形成整體,螺栓的布置及直徑選取直接關系到外圍構件是否能有效約束內核構件的側向變形。為此,該文在雙矩管裝配式防屈曲支撐外圍約束構件剛度取值及其設計方法較完善的前提下,通過考慮外圍約束構件的螺栓布置間距、內核多波變形波長以及因外圍約束構件板件局部變形引起的撬力影響來確定跨中螺栓內力;此外,還提出了端部螺栓的內力計算公式及端部螺栓加強方案,完善了雙矩管裝配式防屈曲支撐螺栓設計理論。
[Abstract]:The peripheral restrained members of prefabricated buckle-resistant braces form a whole through high-strength bolt connections. The arrangement and diameter selection of bolts are directly related to whether the peripheral members can effectively restrain the lateral deformation of the core members. Therefore, on the premise that the stiffness and design method of the external restraint member of the double-moment tube assembly anti-buckling bracing are relatively perfect, the bolt arrangement spacing of the peripheral restrained member is considered in this paper. The internal force of the mid-span bolt is determined by the multi-wave deformation wavelength of the kernel and the influence of the prying force caused by the local deformation of the external restrained member plate, in addition, the formula for calculating the internal force of the end bolt and the reinforcement scheme for the end bolt are also put forward. The design theory of double moment pipe assembly buckling supporting bolt is improved.
