<p>A bridge structure includes an essentially isotropic bridge deck formed of modular deck panels (2110, 2112) spliced to each other on site. The deck panels (2110, 2112) are preferably shop fabricated by longitudinal welding of adjacently placed multi-void elongate aluminum structural elements (102). Longitudinally adjacent elongate elements are spliced by providing internally disposed shear elements (518, 520) prior to longitudinal welding of adjacent spliced elongate elements, with the end joints between spliced elongate elements being arrayed in a staggered manner.</p> |
