钢-混凝土混合结构受力性能实例分析

Case Study on Mechanical Behavior of a Steel-Concrete Composite Structure

通过混凝土结构、钢结构、钢-混凝土混合结构三种不同结构体系的理论分析,阐述了它们各自的受力特点;结合典型高层住宅设计实例,分别采用三种结构设计方案进行比较分析。结果表明:在相同设计条件下,混凝土结构的刚度最大,混合结构次之,钢结构最小;对于抵抗扭转的能力来说,混凝土结构最弱,钢结构最强,混合结构介于两者之间。

In order to study the mechanical behavior of the steel-concrete composite structures,the theoretical analyses and comparisons are performed on steel structures,concrete structures and composite structures respectively.Three structural design plans for a typical high-rise residential building are compared.The results indicate that,under the same design conditions,the concrete structure has the largest stiffness and the steel structure has the smallest stiffness and the composite structure is intermediate.For the torsional capacity,the steel structure is the best,and the composite structure is still between the concrete and the steel structures.
