An Optimization Method for the Intelligent Modularization of Concrete Frame Structures

Low productivity and sustainability are two major challenges in the construction industry. One promising approach to enhance efficiency is modular construction, which utilizes economies of scale while also allowing for the interchangeability and reusability of concrete components. This paper presents an optimization method to reduce the internal variety of a construction kit for concrete frame structures. Based on reference buildings, which present an initial solution space of the construction kit, an optimization of the module variants is carried out by solving a multi-objective, mixed-integer optimization problem. The results show that the number of necessary module variants can be significantly reduced by using an optimization method. Furthermore, an outlook on the application of this method for curvilinear structures is given using the example of a modular shell roof.
