On the Seismic Evaluation of Steel Frames Laterally Braced with Perforated Steel Plate Shear Walls Considering Semi-Rigid Connections

Steel plate shear walls usually do not satisfy the strong-column weak-beam design criteria, leading to larger column sections. On other hand, rigid frame structures are typically constructed in low-rise mid-rise buildings built locations prone strong earthquakes due their high flexibility and cost-effective solutions. Overcoming these restrictions SPSW system, this paper is dedicated employing a semi-rigid connection that dissipates energy well reduces forces applied structure. By using an adjacent span SPSW, actual flexural capacity of beam end decreases and, subsequently, improves performance structure terms criteria. Thereupon, impact connections on steel frames with SPSWs as sideway resisting system can be assessed by implementing numerical study. In paper, new methodology for modelling joints used considering five different moment capacities. Moreover, influence three circular diameters behavior perforated was investigated. To fulfil purposes, nonlinear dynamic analysis conducted assess reliability 5-, 10-, 15-story resisted subjected ground motion records. A total 45 were modelled obtained results compared reference benchmarks. The outcomes studies show good agreement building code requirements. addition, reliable under seismic loads evaluated. According parametric study, presumed allowable drift leads obtaining optimum each model illustrates applicability structural consisting simultaneously.
