![]() Also, the conference includes modern applications in structural engineering, materials of construction, construction management, planning and design of structures, and remote sensing and surveying engineering. This book contains selected articles from the Second International Conference on Geotechnical Engineering-Iraq (ICGE-Iraq) held in Akre/Duhok/Iraq from June 22 to 23, 2021, to discuss the challenges, opportunities, and problems of geotechnical engineering in projects. Thus, the performances of two new generation optimization algorithms in design optimization of a vaulted roof steel structure are compared and the benefits of the application programming interface are demonstrated. ![]() Then, using the application programming interface of the software, integration of finite element model with GWO and BSO optimization algorithms encoded in Microsoft Visual Basic for Application (MS VBA v7) programming language is provided. The vaulted roof steel structure is initially modeled in a finite element packaged software (ANSYS Workbench v18.1). Grey Wolf Optimizer (GWO) and Backtracking Search Optimization (BSO) algorithms that are relatively recent metaheuristic algorithms are utilized as optimizer tools to obtain the minimum weighted structural design. In the design, W-shaped steel profile sections to be selected for assigning to the structural elements are considered as discrete design variables. The structural design constraints of the optimization problem are determined according to American Institute of Steel Construction-Allowable Stress Design (AISC-ASD). And dead loads reobtained in terms of gravity. Wind loads and snow loads are calculated in direction of TS EN and TS ENpractice code specifications, respectively. ![]() The design problem is intended to be as realistic as possible. Weight minimization of the vaulted roof steel structure is considered as objective function of the design problem. The cost of a steel structure is directly related to the weight of the structure. ![]() In present study, structural formation identification of a vaulted roof steel structure is taken as optimization problem. ![]()
