Abstract
In order to further understand the elastic and elasto-plastic stability behaviors of single-layer reticulated domes under static loads, typical cases of single-layer reticulated domes are analyzed and compared by using the finite element software, ANSYS. Based on the results, more than 1000 elastic and elasto-plastic complete-process analyses for the Kiewitt single-layer reticulated domes have been carried out to study the influence of various factors, such as initial geometry imperfection and unsymmetrical action of loads, and quantitative results were obtained. Through a statistical analysis of elastic and elasto-plastic stability critical loads, a plasticity reduction coefficient for the Kiewitt single-layer reticulated domes is proposed to reveal the influence of material nonlinearity on critical loads.
