Small Projects are Big Deals
Geotechnical engineers work on a wide array of projects, ranging from small retaining walls or pavement projects, to construction of dams, canals, and foundations for bridges and high-rise...
Innovations in Geosynthetic Rolled Erosion Control Products: From Forests to Fibers
Over the last 50 years, many different types of geosynthetic rolled erosion control products (RECPs) have emerged, ranging from different structure types to different fiber types. Natural-fiber...
Evaluation of Vertica Retaining Wall Systems
Prepared by the Highway Innovative Technology Evaluation Center (HITEC). This report describes a HITEC evaluation designed to determine the basic capabilities...
Screw Piles and Helical Anchors: 180 Years of Use in Geotechnical Engineering
Since 1836, screw piles and screw cylinders have been used successfully throughout the world to support a variety of large-scale, civil engineering structures. Their development and use...
Foundation Engineering...102
Most of our textbooks still separate foundation options into two simplistic categories: shallow or deep. That's why so many of us are geared toward thinking about the foundation...
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...
Long-Term Performance Monitoring of a Hillside Retaining Wall
To accommodate expansion of the West Point Treatment Plant in Seattle, WA, a 3,000-ft-long soldier pile, tieback-anchored retaining wall was constructed from May 1991 to May 1992. An oblique...
General
Design of Latticed Steel Transmission Structures specifies requirements for the design, fabrication, and testing of members and connections for electrical transmission structures. These...
Loading, Geometry, and Analysis
This Standard applies to latticed steel transmission structures. These structures shall be either self-supporting or guyed. They consist of hot-rolled or cold-formed prismatic members...
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...
Testing
The purchaser shall specify in the contract documents which structures or components of structures are to be tested. If a proof test of a structure or a component of a structure is specified,...
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...
Shafts/Temporary Structures
Shafts should be of a size to accommodate the equipment and pipe selected and to allow for safe working practices. If the shaft must accommodate the permanent works, it is the contractor's...
Construction Support Services
A preconstruction survey of existing structures within the anticipated construction zone of influence should be conducted before any construction begins. A plan for structures that need...
Innovative Use of a Groin Structure: Saving Cost, Shortening the Schedule, and Minimizing Impacts
Almost any type of construction activity can pose a shock to the surrounding environment and habitat. Obviously, the extent of the impact will depend on the location of the project and...
The New Bedford Marine Commerce Terminal
When construction of the first American offshore wind farm support terminal encountered greater challenges than expected, jet grouting enabled construction to continue....
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....
Performance Limits for Deepwater Pipelines
This paper highlights the differences between onshore and offshore pipeline design. It then summarizes the results of combined external pressure, tension, and bending testing on full scale...
Failure of a Twenty-Foot High Retaining Wall
A cantilever retaining wall, designed in apparent accord with provisions in a civil engineering handbook, failed soon after construction. Analyses of the causes of the failure are presented....
