摘要: 大跨度钢木混合结构以其高效、美观及经济性，近年来受到了广泛关注和应用。本文以广州纳米中心圆项目工程为例，对大跨度球状网壳钢木混合结构的施工过程进行数值模拟，并提出关键施工措施建议。首先，利用MIDAS GEN软件对该结构进行分层、整体及不同节点约束的建模。然后，分析有无玻璃荷载及有无环向拉索的工况组合，全面模拟了不同的施工过程对结构的影响。最后，结合现场条件，提出最优施工措施。研究表明，节点约束处理对结构变形有显著影响，刚性节点有利于控制变形；环向拉索在各种条件下均能有效防止变形。因此，建议在施工过程中，节点尽量建造为刚性节点。同时，采用分层施工并施加环向拉索，且每施工完一层，应立即施加拉索。
Abstract: In recent years, large-span steel-timber hybrid structures have garnered significant attention and application due to their efficiency, aesthetics, and economy. Taking the Guangzhou Nanometer Center Circular Project as an example, this paper conducts a comprehensive numerical analysis of the construction process of a large-span spherical reticulated steel-timber hybrid structure and proposes key construction recommendations. Firstly, the MIDAS GEN software is utilized to establish models for the structure at different levels, as a whole, and with various joint constraints. Subsequently, the impact of different construction processes on the structure is comprehensively simulated by analyzing combinations of working conditions with and without glass loads, as well as considering the influence of circumferential tension cables. Finally, an optimal construction scheme is determined based on the actual site conditions. The research reveals that joint constraint treatment has a significant impact on structural deformation, with rigid joints being beneficial for deformation control. Circumferential tension cables effectively prevent deformation under various conditions. Therefore, it is recommended that tension cables be applied in layers during the construction process, and tension cables should be installed immediately after the completion of each layer.
