Knife edge load bridge
WebKnife edge load: In standard loadings, as well as the uniform load, a single line load of about is applied at one point anywhere along the lane on that span. British Standards call this … WebBridge Deck is used to minimize the load application process while complying with national code requirements. The program is based on the use of influence surfaces, which are generated by STAAD.Pro as part of the loading process. An influence surface for a given effect on a bridge deck relates its value to movement of a unit load over the point ...
