Calendar: Bridges 2016
Featured bridges are: Irondequoit Bay Outlet Bridge (Irondequoit, New York); Dongshuimen Bridge (Chongqing, China); South Grand Island Bridge(s) (Grand Island, NY); Salmon Bay Bridge (Seattle,...

A Foundation Engineering Trip Down the Mississippi: Foundations for Mississippi River Bridges from Minnesota to Louisiana
Huckleberry Finn had his adventure, but for those interested in foundation engineering, this article will float you down the Mississippi River on your own encounter with the many bridges...

Spread Footings Revisited: Geotechnical Advances Lead to Expanded Use for Bridge Abutments
The Minnesota Department of Transportation (MnDOT) has historically used steel shell piles to support highway bridge structures, probably due to a blend of familiarity and efficiency among...

Evaluating Bridges With Unknown Foundations for Susceptibility to Scour: North Carolina Applies Risk-Based Guidelines to Over 3,750 Bridges
Scour occurs when flowing water removes erodible material such as sand and rock. For bridges over water, scour affects the stability of pier and abutment foundations and contributes to...

National Usage of Geosynthetic-Reinforced Soil to Support Bridges
The Geosynthetic-Reinforced Soil Integrated Bridge System (GRS IBS) was developed by the Federal Highway Administration (FHWA) almost 20 years ago to help meet the demand for the next...

Very Long-Term Care of Mechanically Stabilized Earth Berms: Limiting the Liability of Future Stakeholders
Since their development over 50 years ago, civil engineering applications of mechanically stabilized earth (MSE) berms have significantly increased. When used as a component of an asset...

Introduction
Many institutions and private industry organizations have prepared guidance documents with the latest scientific and engineering information on proper design, installation, maintenance,...

Design Considerations Common To All Permeable Pavements
Impervious cover in watersheds without controls result in increased stormwater runoff and decreased groundwater recharge in response to rainfall events. This increased runoff can be the...

Porous Asphalt and Permeable Friction Course Overlays
Porous asphalt typically consists of conventional warm mix asphalt (WMA) or hot mix asphalt (HMA) with significantly reduced fines resulting in an open-graded mixture that allows water...

Permeable Interlocking Concrete Pavement (PICP)
Permeable interlocking concrete pavement (PICP) consists of (impervious) manufactured concrete units that form permeable voids and joints, when assembled into a laying pattern. The openings...

Achieving Success and Avoiding Failures with Permeable Pavements
This chapter provides experienced-based recommendations on how to achieve success with permeable pavements. This information is based on an informational survey completed by designers,...

Maintenance
While site selection and proper construction are the most critical factors in establishing that permeable pavements function as designed, all must be inspected and maintained to maximize...

Hydrologic and Hydraulic Design Methods
Computational methods for hydrologic analysis, hydraulic functions, and treatment capacity of permeable pavements vary depending on the complexity of the design and level of detail in...

Permeable Pavement Research Needs
The implementation of permeable pavement installations and practices are expanding and becoming more commonplace. With this increased usage comes expanded and improved information on design,...

Design of Connections
Bolted connections for transmission structures are normally designed as bearing type connections. It is assumed that bolts connecting one member to another carry the load in the connection...

Structural Members and Connections Used in Foundations
This chapter specifies design procedures for steel members and connections embedded in concrete foundations or the earth. Additional design requirements for structural members and connections...

Detailed Site Investigations
This section addresses site investigation issues that are important for detailed design and construction of microtunneling projects. These site investigations include the following: Geotechnical...

Notes on Heavy Lift Design
The interrelated activities and responsibilities of the various organizations involved in the lift design and offshore installation of topside facilities for an offshore platform are discussed....

Findings From a Joint Industry Study on Foundation Fixity of Jackup Units
During the design storm conditions the soil supporting jack-up unit footings may be close to, or at plastic failure. Accordingly, the use of elastic solutions to the problems of foundation...

Extreme Wave-Force Calculation Procedure for 20th Edition of API RP-2A
The paper describes the revised guideline design wave force calculation procedure approved for the 20th edition of the API-RP2A WSD and the first edition of the API-RP2A LRFD and contrasts...
