Structural engineers have to design not only safe and practical buildings in a reasonably short period but also guarantee that the design generated should be cost-efficient. However, the design of real-world structures in a traditional way is an extremely laborious and time-consuming task, and final designs are often uneconomical. In this study, a computationally efficient, design-driven optimization technique (Guided Evolution Strategy Optimization, GES) is developed for the optimal design of real-world steel structures considering the strength, displacement, and geometric constraints in accordance with the conventional design codes. Structural design engineers demand practical, efficient, and robust software platforms that combine the potential of optimization techniques with design software capabilities. In other words, there is a need for a single master software platform that integrates the optimization software and the design software packages. This way, promising solutions for real-world structures can be obtained practically with reasonable computational power and time. This study also developed a reliable, efficient, flexible, and user-friendly software platform called Structural Optimization Platform Software (SOPS) with the abovementioned capabilities to present a robust infrastructure for designing real-world steel structures. The SOPS's structural analysis and design part (design software component) is carried out externally via the Open Application Programming Interface (OAPI) of the SAP2000 structural analysis program. In addition to GES, various metaheuristic techniques are implemented into the SOPS program package to constitute its optimization software component. The numerical results demonstrate the computational efficiency of the proposed technique (GES) for the optimal design of real-world steel structures subjected to geometric, strength, and displacement constraints in terms of convergence rate and quality of the optimum solution. Moreover, the application of SOPS to the optimization of real-world steel structures demonstrates that SOPS successfully combines the potential of the optimization techniques and the design software capabilities (SAP2000). Furthermore, due to SOPS's real-time monitoring ability, the performance of the optimization techniques can be easily observed in real-time.

Optimum Detailed Design of Reinforced Concrete Continuous Beams using the Harmony Search Algorithm Akin, A.; Saka, M. P. (2010-09-17) Design optimization of reinforced concrete structures is more challenging than that of steel structures due to the complexity associated with reinforcement design. In this study, optimum design algorithm is presented for reinforced concrete continuous beams. The design variables are selected as the width and the depth of beams in each span, the diameter and the number of longitudinal reinforcement bars along span and supports, and the diameter of ties. The design constraints are implemented from ACI 318-05 ...
Development of a passive vibration isolation analysis and optimization software for mechanical systems Baytemir, Ozan Yavuz; Ciğeroğlu, Ender; Özgen, Gökhan Osman; Department of Mechanical Engineering (2014) In the design stage of a mechanical structure, the effects of vibration are taken into consideration as important design criteria. In order to eliminate the adverse effects of vibration sources, a direct intervention to the vibration source, structural reinforcement or the use of vibration isolators are encountered as the most popular vibration control methods. Among all, being compact, low cost, reliable and maintenance free, elastomeric passive vibration isolators with linear properties are examined withi...
Optimum design of steel space frames via bat inspired algorithm Hasançebi, Oğuzhan (null; 2013-05-19) Design optimization of steel space frames is a very popular topic in structural engineering due to economy saved in cost of the structures by optimization process. Although the final cost of a steel frame is affected by many factors, such as material, manufacturing, erection and transportation costs, the material cost of steel comprises a great deal of overall cost of the structure. Hence, the design optimization of steel frames is focused on weight minimization in the literature based on the assumption tha...
Multi-objective performance based design optimization of steel structures Eser, Hasan; Hasançebi, Oğuzhan; Yakut, Ahmet; Department of Civil Engineering (2021-5) Seismic performance of structures designed in accordance with conventional force-based design (FBD) codes can vary significantly since (1) estimation and distribution of earthquake loads are based on initial stiffness of members and (2) force reduction factors are based on the rough assumption that all members will yield simultaneously. In recent decades, attempts to predict the seismic performance of structures resulted in the development of several guidelines for evaluation and rehabilitation of existing ...
An automated approach for the design of Mechanically Stabilized Earth Walls incorporating metaheuristic optimization algorithms YALÇIN, YAĞIZER; Orhon, Murat; Pekcan, Onur (2019-01-01) Considered as cost-efficient, reliable and aesthetic alternatives to the conventional retaining structures, Mechanically Stabilized Earth Walls (MSEWs) have been increasingly used in civil engineering practice over the previous decades. The design of these structures is conventionally based on engineering guidelines, requiring the use of trial and error approaches to determine the design variables. Therefore, the quality and cost effectiveness of the design is limited with the effort, intuition, and experie...
