TOPO-Joint: Reliability-based topology optimization framework for 3D-printed building joints

Abstract

A Reliability-based Topology Optimization framework with the integration of a parametric design process and additive manufacturing technique is proposed in this paper. The proposed method is applied to design architectural and structural joints subjected to uncertain load and material property. Optimal joint designs from various architectural and structural design consideration are discussed through numerical applications. A study is conducted on the comparison between deterministic and reliability-based topology optimization approaches.
