| Summary: | under cyclic loading due to discontinuities in the welds and the formation of areas of stress concentrations. It is known that the presence of these cracks reduces the load-carrying capacity of a member and increases the member's susceptibility to fracture. However, the extent of the reduction in load-carrying capacity can only be roughly estimated due to the fact that the depths of these cracks are unknown. The method of Double Reflected Angle Beam Inspection, was devised to decrease the complexity and cost of utilizing ultrasonic investigation in the determination of the depths of cracks located in structural steel members. Double Reflected Angle Beam Inspection determines the depth of a crack in a steel member and can be used to determine the depth of a crack along the crack's entire length. It is hoped that this method, combined with the notion that the greater the depth of a crack the greater the likelihood of failure, will aid in the development of a standard for implementing corrective measures that will reduce a member's probability of failure. |
