Abstract

Small or medium-scales regular railway stations are being widely built. Through an extensive survey of actual modern railway stations, the common ranges of building parameters were determined. Wind pressure measurements of 18 models were conducted by wind tunnel tests to systematically investigate the influence of the canopy width, opening width and waiting hall building height on peak wind pressure coefficients on roof claddings of the canopies and waiting hall building. According to the distribution law of the most critical minimum wind pressure coefficients, roofs of the two canopies and waiting hall building are divided into 19 zones for the convenience of engineering applications. The dependency of the area-averaged most critical minimum wind pressure coefficients on the tributary area in all roof zones of the canopies and waiting hall building are investigated. The fitted formulas to calculate the area-averaged most critical wind pressure coefficients are proposed as a function of the tributary area, which can be used as the reference for determining wind loads during the design of roof claddings of regular railway stations.
