In this research, the study of the final geometry in abrasive waterjet machining of a hybrid CFRTP/Steel structure. A new methodology for the evaluation of taper angle with high accuracy has been developed through image processing. In addition, the surface quality in terms of Ra and Rz has been assessed. A potential-type trend between taper and hydraulic pressure has been established for both materials.

In the design of steel crane girders, various sources of uncertainty such as material properties, loads, and geometric tolerances are inherent and inevitable. Using deterministic structural and/or load conditions may lead to low-reliability systems in real applications. In this paper, the probability of failure of overhead crane bridge girders with uncertain design parameters is investigated. First, the design problem of a crane double girder is introduced within a set of analytical stress and defection constraints.
