An influence surface represents a selective component of analysis results shown at the points of unit load application in a plane surface of a rigid frame or slab bridge. The unit load is applied to all the locations of possible loading on the bridge deck surface, which provides the basis for static analysis. Through an influence surface algorithm midas CIvil thus performs analysis for the vehicular moving load in a rigid frame or slab bridge where the effect of two-way distribution of moving loads is significant.
