Evaluation of out-of-plane bending properties of meshed structures

Abstract

The meshed structures, whose properties vary depending on the mesh shape, are widely used in rockfall protection engineering. At present, the main method for evaluating the out-of-plane deformation behavior of meshed structures are to obtain equivalent properties by analysis, and there are few theoretical considerations. Therefore, the purpose of this study is to propose an evaluation method for out-of-plane deformation behavior based on theoretical considerations and to clarify the scope of its application. In this study, the equivalent properties of various meshed structures were calculated and used to predict the behavior of the meshed structures under out-of-plane loading. The out-of-plane behavior of various meshed structures was predicted theoretically, and the prediction accuracy was validated by using the finite element analysis (FEM).As a result, an efficient method of evaluating out-of-plane deformation according to the size of deformation was proposed and validated.
