Abstract
Three-dimensional (3D) extrusion-based concrete printing is a novel construction strategy having the potential to revolutionize the construction industry and the structural engineering discipline due to its rapid onsite constructability and low construction cost. However, there is no code-based design strategy to capture structural response behavior of 3D printed concrete (3DPC) elements to support design 3DPC structures. In this paper, a reinforcing strategy along with the strength design equations for in-plane loading are proposed for 3DPC walls to enable design of 3DPC low-rise residential and office buildings. To derive design equations, diagonal shear failure and flexural failure are considered. The proposed strength design equations are validated through a numerical study on four 3DPC walls modeled in OpenSees. The numerical results show similar failure mechanisms and strength with the one computed from the proposed equations.
