Abstract:In order to study the bearing capacity and the failure process of the plate-cone cylindrical reticulated shell structure, and understand the mechanical performance and overall stiffness of the structure, a model test on the plate-cone cylindrical reticulated shell structure was carried out. The crucial members including the upper chord node, lower chord node, support node, cone forming and connection structure were designed to ensure the accuracy of the model structure. Loading tests were carried out on the model structure supported by two longitudinal sides under normal load conditions and failure load conditions, and ANSYS software was used to perform nonlinear finite element analysis. The results indicate that the overall stiffness of the plate-cone cylindrical reticulated shell is large. Under the normal load, the deformation of the structure is small, the ratio of maximum vertical displacement to span is 1/3787, and the force of the chord is mainly transmitted along the direction of the arch axis. Under the failure load, local buckling occurs first at the gusset plate of the cone connection joint. Then the solder joint is damaged, and the structure loses bearing capacity. The error between the bearing capacity obtained by the finite element analysis and the bearing capacity obtained by the test is 11% , and the failure mode is basically the same. It can be seen that the finite element analysis method used in this paper is reliable.
