摘要：This paper analyses the influence of eccentricity on inner forces in the elements of a truss grider. A specific planar truss with predefined dimensions was analysed. It’s assumed that web elements are equally rigidly connected to the chords and that the loads are gravitational. The load combination of self weight and one live load is used. Eccentricity is applied first in the lower chord, then in the upper chord and finally in both chords. Eccentricities are calculated as the ratio of the shortened length and the total length of the web element. From the results of the analysis, for the used load combination (self weight + live load) the changes in bending moments and axial forces were observed in the places of maximal compressive axial forces, that is the compressive top cord in the middle of the span and the compressive web element in the first field.
