WebAdditional stress on rail caused by interaction tends to increase in proportion to expansion length on the bridge, which refers to the maximum expansion length from bridge supports; WebFor rail-when the continuously welded rails (which restrict free fastenings also, the track and bridgethe free movements) are laid on the structure move independently, so there is no interactionbecause then the track-structure interaction shows between these. Hence, for these, there is nonon-negligible effects.
