Although experimental studies have proven as the most effective method, its high cost has provoked researchers to seek alternative approaches. The increase in computational power 21st century provides opportunity numerically model with various programs. This study examines comparison of force-based element and displacement-based columns using nonlinear fiber elements. Within scope study, OpenSe...

The introduction of new materials can significantly improve the performance existing dampers, but constitutive model is difficult to be obtained in a short time, which makes its numerical simulation difficult. Bouc–Wen–Baber–Noori (BWBN) well describe stress-strain relationship materials, and it helpful introduce into simulation. In this paper, high manganese steel material used fabricate buckl...

Subsea high pressure/high temperature (HP/HT) pipelines may be significantly affected by the effects of soil structure interaction (SSI) when subjected to earthquakes. Numerical simulations are herein applied assess role deformability on seismic vulnerability an unburied pipeline. Overcoming most contributions existing in literature, this paper proposes a comprehensive 3D model system (soil + p...

A performance-based seismic assessment of unreinforced masonry (URM) buildings requires the use of reliable models, able to predict their nonlinear force-displacement response including their displacement capacity. Among the possible methodologies, at different levels of complexity, macro-modelling using structural component elements has proved to be an approach that can provide satisfactory ac...

The collapse of several tall composite buildings over the last two decades has shown that performance tall, and complex in fire is a necessary design consideration ought to go beyond simple code compliance. To this end, advancements field numerical simulation both thermomechanical response structures have been made. In isolation, practical benefit these limited, their true potential only unlock...

Abstract The seismic vulnerability of bridges may be reduced by the application Geotechnical Seismic Isolation (GSI) below foundations columns and abutments. However, role GSI on response has been limitedly examined in literature. Therefore, this research conducted to study effect applying address aforementioned gap knowledge. Advanced nonlinear dynamic three-dimensional finite element analyses...

Based on the shaking table test, seismic responses of main parameters two-span skew bridge were gutted. The finite element model test was established by analysis software OpenSEES. An improved single beam quality distribution proposed. stiffness end twice that actual beam, rather than rigid arm. At same time, mass distributed in way shares half and beams at both ends share half, taking into acc...
