文摘Based upon nonlinear analysis theories for single-layer reticulated shells under fire conditions,more than 800 FEA models for four types of single-layer reticulated shells(K8,Geodesic,Schwedler,and Lamella) with different geometric parameters were set,and nonlinear finite element complete-process analysis under fire condition were conducted on the two typical cases,i.e.,global non-uniform temperature distribution and localized high temperature.By analyzing the calculation results for elasto-plastic stability bearing capacity,the practical calculation formulae for calculating elasto-plastic stability bearing capacity under fire condition were obtained.
