摘　　要：结合具体的工程实例,分析了橡胶支座、悬臂柱支座、刚铰支座三种支座的受力性能,并对三种支承条件下的网架位移、杆件内力进行对比,通过对三种支座的具体分析,可以得出,橡胶支座条件下网架结构虽然容易发生竖向位移,但是有助于降低网架结构杆件内力,可以减少其受力,为工程的科学设计施工打下基础,同时为相关方面提供一定的借鉴作用。This paper analyzes the mechanical properties of three kinds of bearings of rubber support,cantilever support and rigid hinge support with concrete engineering examples,and then compares the displacement and internal force of the frame and rod parts under three kinds of support conditions. The concrete analysis of the three kinds of supports can be obtained. Although the vertical displacement is easy to occur in the structure of the rubber stand,it can help to reduce the internal force of the rod part of the structure,reduce its force,lay a foundation for the scientific design and construction of the project,and provide some reference for related aspects.
