The geometry of the bridge is directly generated from keypoints to lines and from keypoints to volumes. When meshing the volume, VSWEEP is used to ensure that all concrete elements are hexahedrons. The element size is controlled using LESIZE command and NDIV in L command.  Prestress rebar is modelled by LINK8 element. Reinforced concrete is … Continue reading Construction Simulation of a Prestressed Reinforced Concrete Bridge: Part 1-Geometry and Meshing
