[摘要]對北京四機位大跨度維修機庫吊車在九種工況下的動力影響系數(shù)進行了實際測試。測試結(jié)果表明:吊車大車運行時產(chǎn)生的動力效應(yīng)比小車大,高速運行時產(chǎn)生的動力效應(yīng)比低速大;北京四機位大跨度維修機庫的吊車動力影響系數(shù)應(yīng)取1.20,以往工程設(shè)計中所取的經(jīng)驗值1.10偏?。晃萆w為網(wǎng)架結(jié)構(gòu)體系的大跨度維修機庫吊車動力影響系數(shù)取值范圍應(yīng)為1.15~1.20。

Abstract:The dynamic influence coefficient of the crane of the long-span hangar with four plane positions in Beijing is tested under nine load cases. The test results show that the dynamic effect caused by the crane cart is larger than that caused by the crane trolley, and the dynamic effect of the high-speed running crane is larger than that of the low-speed running crane. The dynamic influence coefficient of the crane of the long-span hangar with four plane positions in Beijing should be 1.20, and the empirical value 1.10 applied in the past project design is relatively small. The value range of the dynamic influence coefficient of the crane of the long-span space truss roof hangar should be 1.15~1.20.
Keywords:long-span hangar; crane; dynamic influence coefficient
