Finite Element Simulation Method of 3D Printed Concrete Structures and Analysis of Arch Stability
Due to the high requirements of 3D printing concrete technology on the working performance of printing materials,there are inevitable test errors in the test process,resulting in a large dispersion of mechanical properties of 3D printing concrete members.The finite element simulation research of 3D printed concrete members by domestic and foreign scholars is still in its infancy,and there are few studies on the basic mechanical properties of 3D printed concrete members with steel bars.Therefore,the finite element simulation method of 3D printed concrete members is proposed,and the stability performance of plain concrete and reinforced concrete arch structures is analyzed.The influence of steel bars and printing molding methods on the stability performance of 3D printed concrete arch structures is investigated.It is found that the bearing capacity of 3D printed concrete arch structure is significantly lower than that of molded arch structure.The addition of steel bars can significantly improve the bearing capacity of the arch structure printed in the vertical arch span direction,but has little effect on the bearing capacity of the arch structure printed in the parallel arch span direction.Adding steel bars can significantly improve the ductility of arch structure.
