Abstract

The results of the Finite Element Analysis of two Warren trusses T1 and T2 are compared with existing experimental results (1]. Truss T1 is made with noded gap joints with a large gap (g = 40 mm), whereas T2 is made with 100% overlap joints with large eccentricity equal to half the depth of the chord. The effect of the weld on the joint flexibility and thus on the truss behaviour is highlighted. 'Semiloof' shell elements are used to model the chord and the branches, whereas 'solid' elements are used for the weld. Some recommendations are given for numerical modelling and for design.
