The paper deals with frame steel structures required to ensure sufficient resistance, appropriate ductility and safety against brittle failure. This special aim cannot be reached by utilizing standard procedures beam elements. Therefore, the present study proposes an innovative design strategy devoted plane frames constituted I-shaped cross-section elements subjected simultaneous combinations of serviceability limit state conditions ultimate conditions. Special factory-made uniform piecewise profiles are utilised provide optimal behaviour frame. proposed consists two subsequent steps: at first a classical sizing is performed utilising profiles, then specific problem define geometry that fulfils all constraints related resistance limited deformability as well introduced protection reliability procedure expected checked performing nonlinear static analyses employing recently Fibre Smart Displacement-Based (FSDB) element model. defined adopting displacement shape functions capable embedding discontinuities means use generalised functions. Furthermore, addressed “smart” since update in accordance development plastic deformations detected fibre discretisation cross-section. results simple portal confirmed structure.

It is well understood that the dominant approach in seismic design of structures to reduce initial cost while meeting required safety level, as dictated by compliance codes. Nevertheless, this often overlooks long-term costs are incurred over lifetime structures. A comprehensive thus for a based on life cycle (LCC), where both and considered. While LCC-based has been employed regular structures, irregular have not received adequate attention. This research aims highlight impact irregularity LCC optimization tall To do this, bi-objective heuristic framework developed balance costs. The used analyze six steel setback with 7, 10, 13 stories. all designed meet performance level. findings show reveal higher sensitivity variations compared which mainly buildings above We also reducing LCCs requires increase structures; example, 13-story 17% resulted approximately 48% 40% reductions LCCs, respectively. Overall, our results confirm more than those ones; an important finding should be considered

Purpose In this study, machine learning (ML) algorithms were employed to predict the shear capacity and behavior of DCSWs. Design/methodology/approach ML Various techniques, including linear regression (LR), support vector (SVM), decision tree (DT), random forest (RF), extreme gradient boosting (XGBoost) artificial neural network (ANN), utilized. The models trained using a dataset 462 numerical experimental samples. Numerical generated analyzed finite element (FE) software Abaqus. These underwent push-over analysis, subjecting them pure conditions by applying target displacement solely top walls without interaction from frame. input data encompassed eight survey variables: geometric values material types. characterization FE was randomly within logical range for each variable. training testing phases 90 10% data, respectively. predicted two output targets: DCSWs likelihood buckling.
