ABSTRACT:
Generally trapezoidal web sections of non-uniform shape for fabricating structural I-section beams having varying bending modulus are cut from rectangular plate stock pieces by a shear whose platen is oscillated, as a series of pieces are cut from a length of metal sheet or plate, about an axis perpendicular to the plane of the stock material. The platen angle is determined and controlled by a computer to which design criteria are fed.
