Numerical Simulation of Rural Brick Buildings Strengthened with CFRP under Flood Actions

摘要

In China,floods often cause life and property losses due to heavily damage and collapse of rural buildings.It is very important to conduct comprehensive research on flood behavior of rural buildings.In this paper,formula of hydrodynamic load imposed on building by flowing flood is derived based on conservation of momentum and test results firstly.Secondly,the finite element analysis of rural brick buildings strengthened with CFRP under flood actions is conducted using ANSYS software to check the effect of CFRP.Simulation results demonstrate that the formula of hydrodynamic pressure and the numerical model of rural buildings are of high accuracy,and can be referenced for further study and applied in engineering practices.
