Summary: This paper presents a novel descent algorithm based on the step-by-step iterative principle, applied to the optimum design of steel frames. The algorithm finds the optimal solution by evaluating the structural weight gradient step by step, while avoiding convergence to infeasible or suboptimal solutions through controlled step size. By choosing the initial solution carefully, the efficiency and convergence speed of the algorithm can be increased. The study also confirms the algorithm's effectiveness in improving optimum designs found by metaheuristic algorithms.

Summary: This paper presents a new and efficient design-driven method, called the capacity controlled search (CCS) algorithm, for sizing optimization of large-scale steel frames under multiple strength and displacement constraints. The CCS algorithm uses a intelligent and probabilistic search strategy based on maximum demand-to-capacity ratios (DCRs) to converge rapidly to the optimum solution. It avoids complex formulations commonly used in other design-driven methods, making the algorithm simple and general. The numerical performance and validation of the proposed algorithm are demonstrated on four steel frame design examples chosen from the literature, showing that the CCS algorithm produces the best-known solutions in the literature.

Summary: In this paper, a new design-driven hybrid optimization algorithm called guided evolution strategy (GES) is proposed for a reliable and rapid optimum design of space steel frames. The GES algorithm improves convergence characteristics of the evolution strategies optimization method by guiding the search process based on the satisfaction/violation of strength constraints in a previous design. The efficiency of the GES algorithm is demonstrated through design examples and compared to other metaheuristic search techniques in terms of accuracy and speed of convergence.
