结合实际工程,从结构方案、性能设计及节点设计等方面对超限复杂钢-混凝土混合结构设计进行了详细论述,并采用多种结构计算程序对其进行弹性、弹塑性分析,评价钢结构、混凝土结构间的相互影响及其抗震性能。同时,钢结构支座均采用可靠性较高的成品支座,并对钢结构关键节点强度进行有限元分析,采取必要的构造措施保证结构的安全可靠。计算表明,对于超限复杂混合结构,当采用合理的结构布置、采取适当的构造措施时,其抗震性能可以满足规范要求。
Combined with the actual project, the design of overcomprehensive steel-concrete hybrid structure is discussed in detail from the aspect of structural scheme, performance design and node design, and the elastic and elastic-plastic analysis are carried out by a variety of structural calculation programs to evaluate the steel structure, Interaction Between Concrete Structures and Its Seismic Performance. At the same time, the bearing of steel structure adopts the highly reliable finished support, and the finite element analysis of the strength of the key node of the steel structure is taken. The necessary structural measures are taken to ensure the structure is safe and reliable. The calculation shows that the seismic performance of the composite structure with overcompensation can meet the requirements of the standard when the reasonable structural arrangement and appropriate structural measures are adopted.
