Experimental study on the synchronization mechanism and trigger characteristic density of vertical evacuation in crowds

Abstract Due to simultaneous horizontal and vertical displacement during vertical evacuation, the consequences of stampede congestion accidents can be more severe.Generally, pedestrians trigger a synchronization mechanism at some point during the vertical evacuation process.This synchronization behavior helps prevent stampede congestion and improve

Experimental Study on the Flexural Performance of the Corrosion-Affected Simply Supported Prestressed Concrete Box Girder in a High-Speed Railway

Prestressed concrete box girders are commonly employed in the development of high-speed railway bridge constructions.The prestressed strands in the girder may corrode due to long-term chloride iphone 14 pramoxine erosion, leading to the degradation of its flexural performance.To examine the flexural performance of corrosion-affected simply supporte
