... stress ratio. Design/methodology/approach This paper proposes an improved stress ratio normalization model. By correcting the slope and translation intercept of the FCGR curves at different stress ratios, the unknown parameters were solved and optimized by combining them with the genetic algorithm...

... composite beams, an optimal cross-section design method based on an improved genetic algorithm is introduced. Design/methodology/approach Taking a 16 m simply supported T-beam as the engineering case study, a preliminary UHPC-NC composite beam cross-section is designed. With material cost minimization...

...Pablo Romero-Tello; Antonio José Lorente-López; José Enrique Gutiérrez-Romero Purpose The main objective is to develop a new design methodology for pressure hulls, prioritizing steel weight reduction without compromising structural safety. Genetic algorithms (GA) will be employed to optimize...

... in MATLAB, namely, genetic algorithms (GA), particle swarm optimisation (PSO) and harmony search algorithm (HSA), were used for structural optimisation to compare the effectiveness of the algorithms. Two life-cycle stages were considered, production and construction stages, which include three boundaries...
