An enhanced harmony search algorithm for optimum design of side sway steel frames

Search group algorithm: A new metaheuristic method for the optimization of truss structures

“…These results emphasize the capabilities of the SGA in this field and encourage its further development and application to other fields as well as real engineering problems, such as the optimization of frame structures [50][51][52]. Next steps in the development of the SGA include, e.g., the refinement of the local phase of the algorithm and the treatment of the constraints without direct penalization.…”

Harmony Search Method: Theory and Applications

“…The HS algorithm proposed by Saka [26] determines the optimal steel section designations from the available British steel section table and implements the design constraints from BS5950. Recently, an Enhanced Harmony Search (EHS) in [27] is developed enabling the HS algorithm to quickly escape from local optima. The proposed EHS algorithm is utilized to solve four classical weight minimization problems of steel frames including two-bay, three-storey planar frame subject to a single-load case, one-bay, ten-storey planar frame consisting of 30 members, three-bay, twenty-four-storey planar frame, and spatial 744-member steel frame.…”

Assessment of the Effectiveness of Cabling System Configuration in Retrofitting Steel-Concrete Composite Buildings

“…Such problems include the sizing of individual members (sizing optimization problems), the selection of the most efficient placing of structural members (topology optimization) or a combination of both in order to achieve a single or multiple goals at the same time (multiobjective optimization). The existing literature is rich of papers proposing and applying optimization algorithms in structural problems [62][63][64][65][66][67][68][69][70][71][72][73][74][75][76][77][78].…”
