【摘要】 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。更多还原

【Abstract】 Based on the real project of complex and composite building which exceeds code limits,the detailed illustration of its structural system concerning concept design,performance design and joint design were presented.Analysis with finite element method(FEM) was conducted to evaluate the anti-seismic property of the structure and the interaction between the steel and concrete.FEM was also applied for the mechanical property of the connecting portion and strength of the joints as well.The detail of construction,as a measure to guarantee the security,had been implemented in the structure.Calculation results show that the anti-seismic capability of the complex and composite building which exceeds the limits with a proper arrangement of structure and appropriate detailing can satisfy the requirements of standard specification.更多还原
