摘要：
The reasonable selection of components’ primary range and performance evaluation method are important prerequisites for efficient and accurate structural design. A quantitative method for defining an acceptable ranges of component parameters was proposed by using the inequality iteration with the different structural components’ bending capacities in steel frame structures. Then, this is applied to a typical semi-rigid steel frame structure optimization method based on yield mechanism control via genetic algorithm and modified cost model, and test using the published experimental data, finite element parameterization modeling and several examples. The results show that, semi-rigid steel frames designed within the recommended ranges will have the desired sequence of component yielding. It can avoid the brittle failure caused by the bolts and connectors. The proposed method helps to limit initial solution domain in structure optimization, and the analysis computational efficiency will be improved. Furthermore, an improved structure’s cost model considering joints and installation was proposed, which can ensure a global optimal scheme is more consistent with the practical engineering. © 2024 Science Press.
