摘要
随着基础设施的发展,在支架现浇混凝土结构上进行施工的工程越来越多,但是支架与混凝土结构如何共同承担外荷载作用、支架的力学变化规律等目前鲜有研究。对此,运用精细化数值分析技术系统性地研究了外荷载作用下支架与混凝土结构的共同受力机理。结果表明,柔性支架的力学状态与刚性支架体系有较大差别,原有的计算方法并不适合类似体系的计算。
With the development of infrastructure, there are more and more construction projects working with cast-in-situ support concrete structure, but there is little research on the structure of the support and the concrete on the mechanism of the interaction between them. In this paper, the mechanism of the interaction between the support and the concrete structures under the influence of external loads is studied by means of numerical analysis. The results show that the mechanical state of the flexible support system is different from that of the rigid frame, and the original calculation method is not suitable for the calculation of the similar system.
