This paper addresses application of an energy-based plastic-damage model for concrete to the modeling of hysteretic responses of reinforced concrete (RC) shear walls. Both damage evolution and plastic flows are accounted for within the framework of thermodynamics, resulting in consistent energy-based damage evolution laws. The model is implemented in the commercial software package ABAQUS via the user-defined material subroutine and applied to two representative benchmark tests of RC shear walls under cyclic loading. It is shown that with the steel reinforcement properly accounted for, the energy-based plastic-damage model can capture realistically the failure modes, load capacities, and overall load–deformation responses of RC shear walls.

It is very important for the wind-resistant design of high-rise buildings to assess wind-induced vibrations efficiently. The Lattice Boltzmann Method-based Large Eddy Simulation and Fluid–Structure Interaction techniques are used to identify the surface wind pressure and wind-induced dynamic response of a CAARC standard high-rise building. Compared with wind tunnel tests, a detailed analysis of the accuracy of simulated wind pressures and base moments of the CAARC model are discussed under multiple wind direction angles. The differences between one-way and two-way Fluid–Structure Interaction simulations are compared under two different reduced wind velocities. The research results show that the simulated mean surface wind pressures of building under seven wind direction conditions have an error within 15% compared to probe measurements, and the average and root mean square base bending moments agree well with the wind tunnel tests. The top transverse wind-induced vibrations of the buildings are significantly larger when the reduced wind velocity reaches 4.6, indicating that aerodynamic damping effects on structural responses should not be overlooked. The research findings of this article provide valuable technical references for the application of LBM methods in the wind load effect assessments of high-rise buildings.
