The closed ring confining truss is set along the periphery of the reticulated shell, and the stiffening truss is set in the middle single-layer shell which can take advantage of the architectural shape. These measures resolve the contradiction between overall stability and temperature stress, and also avoid the shell thrust act on the lower concrete structure directly. Besides, these measures simplify the design of the shell bearing and the concrete structure, and the cost of the concrete structure can also be saved.

网壳通过可径向滑动球铰支座与下部混凝土结构连接，网壳周边设置封闭环形约束桁架，中间单层壳体部分利用建筑凸肋造型设置加劲桁架，解决了保证整体稳定和减小温度应力之间的矛盾，同时避免了网壳侧推力直接传递给下部混凝土结构，简化了网壳支座及下部混凝土结构的设计，节约了混凝土结构的造价。
