采用数值分析方法,研究了在一定用钢量条件下,网格的不同加强方式对单层双曲扁网壳稳定承载性能的影响.在线性、非线性和初始缺陷等各种工况下,通过对不同网格加强方式下的网壳稳定承载力分析计算,考察了该类网壳中各种网格加强方式的合理性.结果表明,网格加强方式对单层网壳稳定承载性能存在较大影响,在实际工程中应合理选用网格加强方式.
The influence of different reinforcement modes of grid on the stability and bearing capacity of single-layer double-decker flat-shelled flat reticulated shells under a certain amount of steel was studied by means of numerical analysis. Under various operating conditions, such as linearity, nonlinearity and initial defects, Through the analysis and calculation of the stable bearing capacity of the reticulated shell under the different grid strengthening methods, the rationality of the various strengthening methods of the reticulated shell in the reticulated shell is investigated. The results show that the existence of the reticulated strengthening mode A greater impact, in the actual project should be reasonable use of grid reinforcement.
