Abstract

Abstract

3D printing technique is the frontier field of intelligent construction and new building industrialization. 3D printing technique has a broad application prospect in the construction field. As one of the main components bearing vertical load in the structure, the bearing capacity of the wall is crucial to the structural safety. In practical engineering, the vertical load of the wall is mostly eccentric. Therefore, the paper designed 10 printed concrete walls considering different cross-section forms, material strength and eccentricity, and conducted eccentric compression test on the walls. It was found that the arrangement of ribs in the printed wall could not only increase the stiffness of the wall section, but also enhance the connection between the two printed wall panels, improve the integrity of the wall, and thus improve the bearing capacity of the printed wall. The higher the cement strength grade, the greater the stiffness of concrete wall section, the smaller the vertical displacement under load. Avoiding the direct force of weak parts of the wall could effectively improve the bearing capacity of components. The increase of eccentricity could significantly reduce the bearing capacity of components and accelerate the failure of components.
