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...

The present paper investigates an innovative seismic-resilient bridge column-footing socket connection (SC) for post-tensioned concrete-filled steel tube (PCFT) columns defined according to the Accelerated Bridge Construction (ABC) requirements. PCFT-SC column uses embedded dissipate seismic energy and unbonded (PT) bars improve self-centering capacity. Experimental tests were performed on a co...

Tradicionalmente se ha concebido que el aprendizaje significativo en los estudiantes logra mediante la comprensión de conceptos o definiciones a través teoría, prácticas laboratorio y campo, además un componente enriquecedor denomina creatividad. Con este antecedente presente artículo tiene como objetivo resaltar elementos del ya enunciados, proceso debe estar acompañado uso herramientas tecnol...

The paper presents the results of a comprehensive study on evaluation effectiveness retrofit strategy existing steel buildings against progressive collapse. In this respect, it investigates performance and design solution to increase robustness Moment Resisting Frame buildings. A truss system added at building's rooftop level (i.e., ‘roof-truss’), intended define an alternative load path, was i...

A novel practical three-dimensional (3D) wheel-rail interaction (WRI) element is developed to simulate the between a fast-moving wheel node and nodes of rail. Different from most previous methods contact in multibody dynamics, relationship this paper simulated by WRI element. The implemented into general finite software framework (i.e., OpenSees), which allows us study not only vehicle behavior...

This study describes the seismic assessment of Archangeloi (Başmelekler) Church in Kumyaka (Sige), Türkiye. The is an important religious monument that has survived to present day from eighth century. Through field surveys, structural system, damages and masonry texture were determined. Pushover analysis was performed with OpenSees software, which advanced nonlinear capability. Damage TC3D mate...
