Abstract
Plate-cone reticulated shell is a new type of double-layer reticulated shell in which ventral members is replaced by cone elements. This paper carries out nonlinear stability bearing capacity analysis on plate-cone reticulated shell considering geometrical nonlinearity of cooperating work between plates and members. In this paper, stability bearing capacity of plate-cone reticulated shells with different kinds of structure form considering geometrical nonlinearity is analyzed by using the software ANSYS, tracking complete process balance path for load-displacement by using arc-length method, the several problems of plate-cone reticulated shell are studied, such as destruction mechanism, structural ductility, stability ultimate bearing capacity and strength reserve, some important conclusions are obtained. After analyzing the stability behavior of double-layer reticulated shell by ANSYS and comparing with plate-cone reticulated shell, it is proved that plate-cone reticulated shell is more advantageous than double-layer reticulated shell in the aspect of stability bearing capacity behavior.
