The objective of this paper is to investigate the response of a cold-formed steel framed building subjected to earthquake excitation primarily through nonlinear time history analysis employing the incremental dynamic analysis (IDA) framework. The two-story archetype building from the Cold-Formed Steel – Network for Earthquake Engineering Simulation (CFS-NEES) project is analyzed using OpenSees....

Abstract This paper investigates the seismic loss assessment of seismically isolated and non-isolated buildings with steel moment or braced frames, designed by design standard ASCE/SEI 7-16. The is calculated from damage to structural non-structural components, as well demolition collapse buildings. study demonstrates that expected annual losses for are half less than those These depend on type...

In this study, the methodology recommended by FEMA P695 is employed to evaluate seismic performance of self-centered y-shaped (SCY) braced frames. To apply system interest, twenty archetype models are deigned. The collapse safety then evaluated through incremental dynamic analyses (IDA) and pushover analyses. results show that secondary stiffness length self-centering (SC) element key parameter...

The ability to perform accurate nonlinear simulations is a key component in the assessment of the behavior of seismic force resisting systems. A three-dimensional distributed plasticity formulation for composite beam-columns suitable for nonlinear static and dynamic analyses of composite seismic force resisting systems has been developed. New uniaxial constitutive relations are developed for th...

Abstract This study presents the impact of near-field and far-field earthquakes on seismic design Intermediate Moment Resisting Frame (IMRF) Special (SMRF) structures through FEMA (Federal Emergency Management Agency) P695 methodology to highlight importance probabilistic collapse as well performance factors these structures. The purpose this is investigate steel intermediate special moment res...

For the first time, 2018 edition of Turkish Building Earthquake Code has added a dedicated chapter for design high-rise buildings in earthquake-prone areas. Keeping view widely practised option rigid shear walls at centre structure, latest code additionally defined limits shear-wall axial forces buildings. The new force have not been independently investigated optimal and criticality. This call...

This paper investigates the seismic performance of Intermediate Moment-Resisting Steel Frame structures considering effects height and soil-structure interaction. For this purpose, three 3D 3, 6 9-story were designed using CSI ETABS software in accordance with ASCE7-16. Then 2D frames simulated by OpenSEES to account for nonlinearity material, plastic hinge elements used. The analyzed IDA metho...

The present study offers a deductive design procedure based on designs that have been optimally screened in accordance with ASCE 41-17's nonlinear static (NSP). subsequent phase inferred linear methodology from the philosophy underlying NSP of 41-17. deduced is applied to provide set optimal 6-story SMRF under two load patterns: code-based and first-mode shape patterns. by proposed are compared...
