Efficient finite element modeling of WT sections subjected to uniaxial tension

Present design specifications for statically loaded tension members do not consider the effects of connection eccentricity as it induces bending in statically loaded members. Previous experimental tests conducted at West Virginia University [WVU] have shown that connection eccentricity induced bending effects have the potential to significantly reduce the net section rupture capacity of a section.;The present study is focused on developing finite element tools capable of capturing the peak loads and behavioral response exhibited is the previous WVU experimental tests. The main objective of the finite element analysis is not only to estimate the failure loads of the WT section specimens but also to trace the entire load versus deflection path. For an accurate representation of the failure load it is essential to capture the underlying necking behavior in the vicinity of the lead bolthole. The finite element analysis is performed using 3D solid elements that are capable of representing large deformation geometric and material nonlinearities. The commercial finite element program ABAQUS is used to perform the analysis. (Abstract shortened by UMI.)
