Abstract

Current research is to use artificial intelligence computation to provide algorithms that meet all Mabhas-6, Mabhas-10, and Standard-2800 regulations of national building codes while minimizing the weight of structures. In previous studies, the control of boundary conditions and optimal design of steel moment frames was done in 2D and only with older algorithms. One of the most important tasks of this research is to perfect new constraint rules to control all constraints and to optimally design the common short and medium length steel structures. All the necessary regulations and controls for the three main types of steel structures widely used in the country: 1) braced frames and 2) frames with shear walls, and 3) a dual system of moment frames and shear walls are implemented. Finally, the results of this algorithm were validated in the Tabriz hospital project. One of the valuable results of this work is that it facilitates a safe design and control process for steel buildings by providing a graphical panel of model inputs and displaying all the key results of the structure in the form of text and diagrams. The work process is intelligently programmed to automatically run by simply inputting a standard ETABS file into the optimal seismic design process algorithm. In the ETABS file, each group sections are defined as a list to allowing artificial intelligence algorithms to choose the best placement. The hospital project demonstrated design safety as well as the ability to significantly reduce the total weight of the steel.
