This research aims to investigate the extent that an incorrect assumption for soil type may endanger seismic safety of moment-resisting steel frame structures using probabilistic assessment. To this aim, first, a set were designed site class C. The examined 3-, 6-, and 9-storey frames according ASCE7-16. Then, assuming actual had been B, C, or D, vulnerability assessments performed OpenSees sof...

The offshore wind turbine (OWT) is a high-rise structure that extremely sensitive to dynamic loads such as wind, waves, and earthquakes. Therefore, in order avoid resonance, it important accurately calculate the natural frequencies of OWT at design stage. integrated finite element model DTU (Technical University Denmark) 10 MW established based on OpenSees software. correctness superstructure s...

To investigate the seismic behavior of wall pier a covered bridge, multi-layer shell element in OpenSEES was used to carry out numerical analysis under horizontal low cyclic loading weak axis direction. The effects mesh divisions models were evaluated and hysteretic curves, skeleton bearing energy dissipation capacity, stiffness degradation displacement ductility with different lateral modes ma...

A common lateral force resisting system for cold-formed steel (CFS) buildings consists of shear walls sheathed with oriented strand board (OSB). Previous experimental and computational research on CFS shear walls, as well as those with other framing materials, has demonstrated that the complex interaction of the fasteners with the sheathing is an important factor in the nonlinear behavior of th...

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....

The catastrophic events of September 11, 2001, stand out as a major motivation for research on improving the understanding structural behaviour in fire. These included first complete collapse tall steel framed structure solely due to World Trade Center 7 (WTC7) was 47-storey office building within WTC complex that collapsed fire initiated by debris from WTC1. In following years, detailed invest...

Since the tragic event of World Trade Centre (WTC), efforts to understand realistic fire behaviour in tall buildings are accelerated. It is critical dynamics involved a compartment before performing forensic investigation accident. In this paper, various scenarios considered simulate high-rise building and demonstrated case Plasco Building using computationally fluid (CFD). Two fuel distributio...

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...
