Abstract
This paper presents a method to analyze elastic deformations and stiffness in two-dimensional structures with different assembly configurations among their elements. Initially, the optimal structure is obtained through topology optimization, and then a method to analyze different types of connections (hinge, flexible and rigid connections) in structural components is developed. Next, two widely documented examples are developed and validated. The versatility of the method and its functionality during both the design process and the selection of the best assembly option are determined. This work contributes to analyzing structures with different interconnection setups among their elements. Existing work is complemented through both the integration of topological design and the choice of the best setup features for a number of cases where assembly and design requirements are related.
