In order to address the difficulty in determining seismic damage probability of continuous girder bridges under construction, vulnerability analysis method construction state is proposed this study. Firstly, taking a long-span prestressed concrete composite box bridge with corrugated steel webs (OSW) as an example, finite element models (FEMs) dynamic calculation different phases cantilever are...

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 corrosion of steel reinforcement negatively influences the mechanical performance reinforced concrete (RC) elements reducing both their strength capacity and ductility. Especially in seismic prone areas, degradation cyclic behavior corroded RC is more intense, limiting service life structures leading to premature failures. In present paper, order study degraded embedded (in concrete) under ...

Centrifuge modelling is an effective tool to assess the response of reduced-scale structures subjected earthquakes under increased gravity. Space limitations, however, force model be contained within relatively small boxes, whose boundaries may affect seismic performance structure consideration. In this paper, influence proximity equivalent shear beam (ESB) container during dynamic centrifuge t...

Global level assumptions of numerical models have received relatively less attention, but been indicated to be a major source error in modeling Reinforced Concrete (RC) structures. In parallel, it has stated that statistical approach involving many virgin specimens and ground motions is necessary for model validation. Such an would require very small-scale testing. Then, the reinforcement fabri...

This paper investigates the behavior of high-rise composite buildings with shear walls and concrete-filled steel tubular (CFST) columns using a numerical model in OpenSees. In model, geometric material nonlinearity structural elements are captured by utilizing fiber force-based beam-column rigorously modified stress–strain relationships. Besides, confining effect concrete core, semi-rigid conne...

For the lifetime assessment of running safety a train in aggressive environments and earthquake-prone areas, effects corrosion on seismic performance must be considered. Research trains, including damage, is limited, despite fact that trains high-speed railway bridges has been extensively examined. In this work, was evaluated using time-varying corroded bridge finite-element model established O...

Liquefaction has caused severe damages to structures such as excessive settlements, tilting, lateral spreading etc., all over the world during many past earthquakes. Hence, efficient prediction of liquefiable soil behavior is crucial for liquefaction-induced hazard evaluation existing and design new in seismically active regions. In this study, a series nonlinear effective stress analyses are c...

Structural health monitoring (SHM) is of great significance for post-earthquake damage assessment. Smartphone-based techniques provide the possibility to perform crowdsensing all buildings in urban regions after an earthquake. However, this idea still faces many difficulties and hard realize. Fortunately, development game engines provides opportunity simulating kind experiment. The main objecti...
