Calibration of Jackup Leg Foundation Model Using Full-Scale Structural Measurements
The fitness of jack-up rigs to operate in varying water depths and weather conditions is determined by "site-specific" structural assessments. These assessments are conducted by a wide range of companies...

Diving Into Engineering
When the underwater portions of a bridge or waterfront facility need to be inspected, the right person for the job is often an engineer diver, a specially trained professional who understands load paths...

Cracking the Nuclear Code: Finding an Alternative to the Nuclear Density Gauge
Two of the most basic quality control tests made in the field during soil construction are the soil’s moisture content and density. The establishment of a uniform procedure to compare the performance of...

A Faculty Internship: Reconnecting with the Profession
After spending eight years as a full-time academic administrator at Lafayette College in Easton, PA – one of only a handful of institutions where discipline-specific engineering programs are embedded in...

Optimized Drilled Shaft Design through Post-Grouting: Shorten That Shaft for Better Performance
Tip post-grouting is a technique used to inject, under pressure, a neat cement grout beneath the base of a drilled shaft. This method enhances or improves axial load-displacement performance by increasing...

Geotechnical Aspects of Pavements: There's More to Roads than Asphalt and Concrete!
When you jump on the highway to make that commute to work, do you think much about what's under the surface you ride on? Pavements are layered systems designed to provide a strong structure to support...

The Evolution of Launched Soil Nails
A 30-Year Retrospective
Launched soil nails are a unique remedial technology in the geotechnical construction toolbox. These 20-ft-long, 1.5-in.-diameter nails are installed in a single shot using a compressed air "cannon" at...

Pervious Concrete
Pervious concrete consists of a hydraulic cementitious binding system combined with an open-graded aggregate to produce a rigid pavement with typically 15% to 25% interconnected void space....

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...

Pipe Characteristics
Microtunneling pipe should meet the following general requirements: Circular shape with a flush outside surface (including at the joints); Strength sufficient to withstand both the installation...

Pipe Design
The pipes and joints, once installed, must be capable of safely withstanding, for the project design life, all in-use service loads, including those associated with the following factors:...

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...

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...

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...

A Simple Model to Predict Soil Resistance to Driving for Long Piles in Deepwater Normally Consolidated Clays
As the exploration and development for offshore oil and gas reserves moves into the deepwater environment of the continental slope, a good model is necessary to evaluate drivability of...

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...

Radial Flow Consolidation Testing
A radial flow consolidation cell that can be used with commercially available loading frames was developed and a series of tests were performed on samples of sedimented kaolin. Simple...

Axial Load Capacity of Pipe Piles in Sands
The axial load capacity of driven, open-ended, steel pipe piles in cohesionless soils, is often estimated using a method such as the American Petroleum Institute Recommended Practice 2A...
