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...
The Joint Industry Development of a Recommended Practice for the Site Specific Assessment of Mobile Jackup Units
The mobile self-elevating (drilling) unit, or jack-up, has been central to the exploration and development of offshore oil and gas reserves. In recent years there has been an increased...
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...
The Hail Problem
Unlike some other forms of precipitation, hail comes in bursts of short duration, falls over isolated and unpredictable locations, and usually occupies only a small percentage of the total...
The Design of Hail Suppression Operations
When hail suppression operations are being considered, it is already understood that hail damage is a significant problem in an area in which the political subdivision, organization, or...
New UCLA Music Buildings Provide Recording, Practice, and Social Spaces
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...
Behaviour of Open-Ended Pipe Piles in Sand During Installation and Loading
An experimental study was performed to investigate the physical processes which influence the axial load capacities of open-ended steel pipe piles in sand. A double-walled pipe pile was...
Performance of Suction Caissons in Sand and Clay
The use of suction caissons (suction piles) in marine environments has been increasing in the last decade. A suction caisson is a steel pipe with an open bottom and a closed top that is...
Pile-Driving Formulas for Friction Piles in Sand
Dynamic pile-driving formulas are widely used in predicting the load-carrying capacity of friction piles and in writing pile-driving specifications. Further, when load tests are available,...
Axial Capacity of Steel Pipe Piles in Clay
Development of theories for the prediction of the axial compressive and tensile load capacities of driven piles is made difficult by a variety of factors, e.g., disturbance of the soil...
Application of Model Pile Tests to Axial Pile Design
Experiments conducted with instrumented model pile segment probes at Harvey and Empire, Louisiana are summarized and the observed behavior interpreted. Correlations are developed for the...
