66 Mitigation of Weldment Cracking in Steel Highway Structures Due to the Galvanizing Process were conducted in SHG and SHG + 0.1% Bi + 1.0% Pb for notched specimens, HAZ-simulated specimens, and cold-worked specimens. Test results yielded the following findings: 1.

Summary and Recommendations for Research 67 were 252-type, not the 505-type used for investigating, and were notched to ensure failure at mid-length. Thus, the results reflect both the influences of notching and HAZ microstructures.

68 Mitigation of Weldment Cracking in Steel Highway Structures Due to the Galvanizing Process Computational Simulations Thermal-mechanical analysis of 19 HMIPs was performed to evaluate the effect of structural configuration on nonlinear stresses and strains during the HDG process. The models were calibrated to thermal measurements taken from an HMIP structure during galvanizing, and a parametric study was performed to investigate the influence of pole thickness, base plate thickness, and pole shape (round versus polygonal; number of sides)
