Disclosed is a seismic load transmitting system based on impact mechanism for a multi-span continuous bridge. There are impact assemblies connected to a superstructure of the bridge for colliding with movable support piers according to a longitudinal displacement of the superstructure of the bridge caus...
Impact load caused by pump pipe hitting deck placer in terms of reciprocating motion subjects the falsework to horizontal dynamic forces. Currently, we do not know much about this kind of load. Based on the investigation results at 18 construction sites, the reciprocating motions of the pump pipe...

Various studies undertaken in order to ascertain formulas which could determine the amount of load railway bridges could sustain are given. It is stated that while the present code results in safe bridges, no studies have gone far enough in ascertaining a useful formula for loads on reinforced co...
