Abstract: In the design, fabrication, and erection of grid shells, a major challenge is the nodal connector between members. Designers typically select a structure’s form and then design the nodal connectors to meet geometric and ...

Abstract: This paper experimentally and numerically evaluates the participation of bridge rail in carrying live load through (1) performing field testing on steel and prestressed concrete girder bridges; (2) developing validated ...

Abstract: This paper introduces a new strategy for the accelerated fabrication and erection of steel bridges: a modular joint. The modular joint is a prefabricated, nodal connector composed of a weldment/built-up section of webs and ...

Abstract: This paper presents built-up press brake-formed tub girders (PBTGs) as a new approach for the fabrication of resilient, short-span steel bridges. In contrast to existing PBTGs that are cold bent from a single steel plate, ...
