February 26 - The Iowa LTAP is hosting a free webinar for bridge professionals on the design and installation of press brake tub girders. The steel .. Read more industry has developed technological and design innovations for bridges under 140 feet that save significant time and costs for county and state bridge officials. Presented is the methodology used for the design of this system along with experimental validation of the modular composite girder’s flexural capacity and recently develop standards. Using experimentally verified analytical methods, the applicability of AASHTO specifications in computing the flexural capacity of the proposed system was assessed. Results of this study show that AASHTO specifications are conservative when employed to compute the composite girder’s ultimate capacity. Therefore, a more accurate means of computing the capacity of the proposed system are proposed. February 5 – The Iowa LTAP is hosting a free webinar on the design and installation of buried soil bridge structures.
