中文摘要：

对由双曲壳和倒置圆锥壳组合而成的复杂钢网壳屋盖进行了研究,阐述了结构选型原则和内力分析结果,对组合网壳的非线性稳定进行了分析.结果表明,下部混凝土楼层和环向杆件对结构的稳定承载力有较大影响,前屋盖和屋脊主桁架之间应采用两向位移耦合连接.

英文摘要：

A study of the complex steel reticulated shell composed of a hyperbolic shell and an inverted conical shell is carried out. The principle of structural design and results of mechanics analysis are expounded. Moreover, the analysis of nonlinear stability is completed. Results show that the influence of concrete building and the circular bars to structural stability performance is notable. And the coupling connection in two directions should be used between the front roof and main truss.
