A gusset plate can form the entire connection or it can be used in conjunction with bolts or welds. [2] There are several prominent connection types that include gusset plates, which include KT gusset plates, uniform force bracing connections, and bolt groups. A KT gusset plate connects several members together through one gusset plate. The ...
An extradosed bridge employs a structure that combines the main elements of both a prestressed box girder bridge and a cable-stayed bridge. [1] [2]: 85 [3] The name comes from the word extrados, the exterior or upper curve of an arch, and refers to how the "stay cables" on an extradosed bridge are not considered as such in the design, but are instead treated as external prestressing tendons ...
The deck is the roadway or walkway surface. In roadway applications it is usually a poured reinforced concrete slab, but can also be a steel grid or wood plank. The deck includes any road lanes, medians, sidewalks, parapets or railings, and miscellaneous items like drainage and lighting.
A scaled down version of this design, the Small Box Girder Bridge, was also formally adopted by the Army in 1932. This latter design was copied by many countries, including Germany, who called their version the Kastenträger-Gerät (K-Gerät for short). [2] The United States was another country whose army created their own copy, designating it ...
The deck is flexible and lies on the main cables, which are anchored to the earth. Underspanned suspension bridge: an early 19th-century descendant of the simple suspension bridge. The deck is raised on posts above the main cables. Stressed ribbon bridge: a modern descendant of the simple suspension bridge. The deck lies on the main cables, but ...
The king post is the central, vertical member of the truss. Crown posts in the nave roof at Old Romney church, Kent, England. A king post (or king-post or kingpost) is a central vertical post used in architectural or bridge designs, working in tension to support a beam below from a truss apex above (whereas a crown post, though visually similar, supports items above from the beam below).
The orthotropic deck may be integral with or supported on a grid of deck framing members, such as transverse floor beams and longitudinal girders. All these various choices for the stiffening elements, e.g., ribs, floor beams and main girders, can be interchanged, resulting in a great variety of orthotropic panels.
When supporting the deck, the cables will instead form a parabola, assuming the weight of the cables is small compared to the weight of the deck. One can see the shape from the constant increase of the gradient of the cable with linear (deck) distance, this increase in gradient at each connection with the deck providing a net upward support force.
