FINITE ELEMENT ANALYSIS ON THE BEHAVIOR OF 3D PRINTED CONCRETE UNDER COMPRESSION AND HIGH TEMPERATURE

Abstract

The problems related to construction remain unsolved, e.g., increasing of cost materials and worker and the need of skilled labor. Therefore, using of three-dimensional (3D) printing concrete technology can solve these problems. However, 3D printed concrete structure is still lacking knowledge, especially concrete behavior under high temperature. Thus, a model of 3D printed concrete wall was developed using ANSYS. The wall had dimensions of 12 cm depth. 132 cm width and 77 cm height. After that, the vertical were applied to the model during exposure to high temperature. The results show that the strength of 3D printed concrete wall at high temperature was lower than that of unheated concrete. Additionally, the buckling failure could be observed when the load applying during exposure to high temperature.
