Nonlinear Reduction Analysis of Defects on Reticulated Shell Structure Bearing Capacity

Abstract:

To study the effect of various types of defects on the bearing capacity of reticulated shell structures, this paper analyzes the structural nonlinear mechanics performance under physical defects and geometric defects, combining with the matrix displacement method of structure, obtains the impact law of two defects on the reticulated shell structural bearing capacity. Two reduction methods of corresponding defects are put forward which can be used as reference in engineering design and construction. Afterwards, it is pointed out and demonstrated that the safety factor should be defined by a lot corresponding experiments.
