identifying at least one plausible load path and ensuring that no portion of
the load path is overstressed.
This case study pertains to the gantry crane beam at the Maryland Port
Authority Harbor as shown in Figure 13.13a (Fu 1994; Fu et al. 2005).
The beam section is 1.83 m (6′) deep by 0.61 m (2′) wide and has five
spans, each 1.83 m (6′). 135# gantry rail on continuous base plate (1/2″ or
12.7 mm thick by 24″ or 609.6 mm wide), anchored with the beam and
the whole assembly, is encased except for the top 25.4 mm (1″) of the rail
