Abstract
Topologically interlocking joineries (TIJs) are structures that connect different parts by using only the geometry and topology of the contact area. Owing to new manufacturing facilities such as 3D printers, new attention toward TIJs increased in recent years. However, there is a lack of structural analysis and application of joints in large-scale structures for current designs. In this study, to reduce the complexity of three-dimensional analysis of large-scale structural simulations, TIJs are replaced with proposed new user-defined elements developed and implemented to be used with finite element software, ABAQUS. Furthermore, the accuracy of this method is discussed by comparing the results of the proposed model and full-solid elements model. Finally, case studies are presented to illustrate the application of this method in the large-scale structural analysis.
