... angle iron at both ends and boxed I-beams in the truss center. The joint stress analysis revealed that large local bending stresses across the transition joint were caused by section change (centroid offset) and fillet weld area offset. The truss collapse was due to a poorly designed lower chord...

... a corrosion rate of about 0.25 mm/yr (0.01 in./yr). Two tanks were constructed of 4.8 mm ( 3 16 in.) type 316L plate, supported in an angle iron framework, and were equipped with type 316L heating coils and agitators. After a few months of service, appreciable corrosion was noted, particularly...
