摘要: 观音圣坛建筑外轮廓呈逐层内收的退台形式,主体结构采用曲线核心筒+转换桁架+混凝土拱顶的巨型框架结构体系,通过将主次结构分离来实现特殊的外立面建筑造型. 对比分析了不同楼板及基础梁刚度,保证了巨型框架柱的水平力平衡;利用桩基抗剪承载力、基础被动土压力复核不同地震作用下基底剪力平衡的安全系数;采用了内埋钢骨斜撑的剪力墙,解决了竖向荷载下倾斜核心筒较大的附加弯矩以及与转换桁架的关键连接传力;子结构通过采用下部双层混凝土斜交网格+上部单层铝合金网壳的组合结构,实现结构与建筑室内一体化设计,同时采用下部、上部设置预应力环梁、网格找形来平衡底部水平力,提高上部开口部位竖向刚度及减小单层网壳的面内变形. 结果表明结构体系合理、有效、安全.

Abstract: The outer contour of the Guanyin Temple building is in the form of a setback that is retracted layer by layer. Themain structure adopts the structure system of special⁃shaped mega core tube + transfer truss + concrete dome to separate theprimary and secondary structures and realize the architectural modeling of special⁃shaped facade. The stiffness of differentfloor slabs and foundation beams was compared and analyzed to ensure the horizontal force balance of giant frame columns.Using pile foundation shear capacity and foundation passive earth pressure to check the safety factor of foundation shearforce balance under different earthquake levels. The shear wall with embedded steel diagonal bracing was adopted to solvethe large additional bending moment of the inclined core tube under vertical load and the key connection force transmissionwith the transfer truss. The sub⁃structure realizes the integrated design of the structure and the building interior by adoptingthe combined structure of the lower double⁃layer concrete oblique grid and the upper single⁃layer aluminum alloy reticulatedshell. At the same time, prestressed ring beams and grid form⁃finding were used in the lower part and upper part to balancethe horizontal force at the bottom, improve the vertical stiffness of the upper opening part and reduce the in⁃planedeformation of the single⁃layer reticulated shell. The results show that the structure system is reasonable, effective and safe.

Keywords:Guanyin Temple; architecture⁃intergated structure; mega frame; concrete oblique grid; aluminum alloy reticulated shell
