This course is an overview of the USACE requirements for design, inspection, and evaluation of hydraulic steel structures(HSS). It is designed to provide guidance in the best practices for maintenance, repair, or replacement of HSS. Nondestructive testing techniques that may be used during periodic inspections or detailed structural inspections are discussed. Guidance is provided on material testing to determine the chemistry, strength, ductility, hardness, and toughness of the base and weld metal. Analyses methods that can be used to determine structure safety, safe inspection intervals, and expected remaining life of the structure with given operational demands are presented.
