N2 - Shear lag can be described as a phenomenon that creates a loss in resistance in a tension member connected through only part of its cross-section. It is a complex problem which has been under study for many years by researchers. Parameters that influence the shear lag phenomenon are many and difficult to assess: type and size of cross-section, type of connection, length of welds, length of member, joint eccentricities, etc. Connections between double-angle web members and chords in trusses or open web steel joist are considered herein. Finite element analyses of such connections were done using ANSYS with solid elements and non linear material. Comparisons between calculated stresses and strain gauge readings from tests done previously by the authors show excellent agreement, both at the yield and ultimate load levels. A parametric study of the connections using finite element analyses is described, and the influence of the different parameters is established. Finally, tentative conclusions are drawn regarding the influence of shear lag in double angle truss connections.
