Construction Numerical Simulation of Cable-Supported Barrel Shell Structure Considering Construction Nonlinearity

Abstract

Based on an actual construction process, this paper put forward a nonlinear simulation analysis method, which can take the mutual influence between structural forming and the tensioning of the active-cables into account. The proposed method shows good performance in solving the problem of structure layout finding and the pre-stress calculation of pre-tensioning tendons by stages and in group. The method has clear mechanical conception and is of reference value for similar construction analysis.
