Abstract Reinforced concrete (RC) buildings are commonly used around the world. With recent earthquakes worldwide, rapid structural damage inspection and repair cost evaluation crucial for building owners policy makers to make informed risk management decisions. To improve efficiency of such inspection, advanced computer vision techniques based on convolutional neural networks have been adopted in research rapidly quantify state (DS) structures. In this article, an object detection network,...

The marketization of data elements is a critical step in harnessing the potential as “new” economic element. This process essential for driving digital transformation manufacturing enterprises and achieving sustainable development. Using from listed (2013–2022), this study applied difference-in-differences method to analyze how accelerates transformation. results indicated that trading platforms play significant role by lowering enterprise costs, easing financing constraints, fostering...

SUMMARY Non‐ductile reinforced concrete buildings represent a prevalent construction type found in many parts of the world. Due to seismic vulnerability such buildings, areas high activity non‐ductile pose significant threat safety occupants and damage structures can result large financial losses. This paper introduces advanced analytical models that be used simulate nonlinear dynamic response these structural systems, including collapse. The state‐of‐the‐art loss simulation procedure...

It has been observed in recent earthquakes worldwide that even countries with modern building codes suffer significant structural damages because earthquake energy is dissipated through inelastic deformation of components. Unrecoverable and prolonged downtime can be minimized using resilient structures, where specially designed detailed fuses. Fuses are decoupled from gravity system replaced efficiently. Earthquake-resilient fused structures cannot routinely unless there a simple design...

Abstract The increasing need to reduce damage and downtime in modern buildings has led the development of a low‐damage design philosophy, where earthquake loads can be resisted with confined easily replaceable components. Post‐tensioned (PT) concrete walls have emerged as popular structural system that been implemented range buildings. In order provide essential evidence support structures, system‐level shake‐table test was conducted on two‐storey wall building implementing state‐of‐art...

Abstract Structural bolts are critical components used in different structural elements, such as beam‐column connections and friction damping devices. The clamping force is highly influenced by the bolt rotation. Much of existing vision‐based research about rotation estimation relies on traditional computer vision algorithms Hough transform to assess static images bolts. This requires careful image preprocessing, it may not perform well situation complicated assemblies, or presence...

Balloon type cross laminated timber (CLT) rocking shear walls are a novel seismic force resisting system. In this paper, the performance of four 12-story balloon CLT walls, designed by structural engineering firm located in Vancouver (Canada) using performance-based design procedure outlined technical guideline published Canadian Construction Materials center (CCMC)/National Research Council Canada (NRC), is assessed. The prototype was investigated nonlinear time history analyses. Robust...

The crosstalk between oncogenic signaling pathways plays a crucial role in driving cancer development. We previously demonstrated that dietary polyphenols, specifically resveratrol (RSV) and other stilbenoids, epigenetically target oncogenes for silencing via DNA hypermethylation breast cancer. In the present study, we identify signal transduction regulators among RSV-hypermethylated targets investigate functional of RSV-mediated regulation Hedgehog Wnt signaling. Non-invasive ER-positive...
