结合钢网架与混凝土框架结构的实际工程项目,考虑采空沉降区变形对结构内力的影响,采用MIDAS/Gen软件,建立钢网架与下部钢筋混凝土框架结构的整体模型,输入采空区地表变形,提取网架各杆件的内力,分析采空区变形对网架内力的影响大小。给出采空沉降区使用钢网架与混凝土框架结构体系的可行性结论,对相关结构设计提出设计建议。 Combined with the actual project of steel truss and concrete frame structure, considering the influence of the deformation of the mining subsidence area on the internal force of the structure, the overall model of the steel truss and the lower reinforced concrete frame structure is established by using MIDAS / Gen software. Deformation, extraction of the internal forces of each rod grid, the analysis of the impact of the deformation of the gob the size of the internal force of the grid. The feasibility conclusion of using steel truss and concrete frame structure system in goaf subsidence area is given, and the design proposal of relevant structure design is given.
