On the heels of its design for a radical sports and leisure venue on the edge of Las Vegas, the Los Angeles-based architecture firm M-Rad has designed a unique tower for downtown Las Vegas that is meant to integrate working and living spaces in circular fashion...
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...
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...
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...
As I See It: Enhancing Geotechnical Practice in Support of Performance-Based Design at Ports
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....
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...
Seismic Design
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...
The Leaning Towers of Wilmington, Delaware: Emergency Response and Retrofit of the I-495 Viaduct to Address Lateral Squeeze
On a sunny, summer afternoon last June, the project manager for AECOM's open-end bridge design contract with the Delaware Department of Transportation (DelDOT) received an...
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...
