Construction Bridge Surveying
Construction Bridge Surveying This course is designed to provide engineers with the logistical and technical requirements associated with bridge surveying as part of a construction project. Bridge surveying is necessary to locate a site, obtain information for design, and furnish lines and grades for construction. A reconnaissance survey is made at all possible sites. A…
Continuously Reinforced Concrete Pavement
Continuously Reinforced Concrete Pavement This course provides information on best practices in rehabilitation strategies for extending the service life of continuously reinforced concrete pavements (CRCP). The procedures described consist of defining the problem, identifying potential solutions, and selecting the preferred rehabilitation alternatives. The rehabilitation strategies described comprise two categories: restoration and resurfacing. Restoration activities preserve…
Bridge Deck Design
Bridge Deck Design The primary function of a bridge deck is to support the vehicular vertical loads and distribute these loads to the steel superstructure. This course provides practical information regarding the decking options and design considerations for steel bridges, presenting deck types such as concrete deck slabs, metal grid decks, orthotropic steel decks, wood…
Bracing System Design
Bracing System Design Bracing systems serve a number of important roles in both straight and horizontally curved bridges. The braces provide stability to the primary girders as well as improving the lateral or torsional stiffness and strength of the bridge system both during construction and in service. Depending on the geometry of the bridge, braces…
Design for Constructibility
Design for Constructibility In many cases, bridge designers concern themselves only with checking the stability and member stress levels in the structure for the in-service condition after erection of the entire superstructure is complete. But many times the critical stress in a particular component is encountered during the erection of the bridge where large unbraced…
Selecting the Right Bridge Type
Selecting the Right Bridge Type One of the initial choices to be made by the bridge designer is to select the most appropriate bridge type for the site. While this choice is not always straightforward, selecting the right structure type is probably the important aspect of designing a cost-effective bridge. This course provides bridge designers…
