This paper presents a recent developed rational simulation method by the authors based on the 3D rigid body spring model (RBSM). In the developed mesoscale simulation method, all the parameters used were proposed with clear and precise physical meanings and straightforward calculation methods. The ...
3D RBSMFlexural behaviorFRPLocal bond modelMesoscale simulation? 2024 The AuthorsA widely adopted method of strengthening existing reinforced concrete (RC) structures, especially for marine concrete structures, is to use external bonded fiber-reinforced polymer (FRP). However, although numerous studies in...
Constitutive models at the meso scale are developed for the 3D RBSM analysis. Failure behaviors and strengths in compression and tension of mortar and concrete are predicted well by the analysis. In biaxial compression test of concrete, crack in normal direction to plane of ...
The method integrates a model predictive control (MPC) algorithm with a three-dimensional Rigid Body Spring Model (3D RBSM) to estimate internal corrosion levels from observed cracks and a normal 3D RBSM simulation to predict the residual performance. The proposed system is validated through analysis...
In this study, a 3D Rigid Body Spring Model (RBSM) is employed to simulate the process of concrete drying. An input strain model that takes account of various environmental factors is established and validated against previously reported experiments. Totally, four kinds of environmental factors are...
Analytical Investigation of Failure Behavior of Beam-Column Knee Joint with External Steel Plates Anchorage Using 3D RBSMExternal steel plates anchorage is one way to reduce the reinforcement congestion inside the beam-column joint because the reinforcing bars of the beam and column are anchored using...
3D RBSM is advantageous because the concrete is randomly meshed to reduce mesh bias on crack propagation and the actual geometry of the deformed bars is modelled. The simulation results clarify that the presence of thicker cover delays crack initiation but increases the rate of crack opening. ...
