Guidelines for structural loads on electrical transmission structures were prepared by the American Society of Civil Engineers' Committee on Electrical Transmission Structures....
A Field Study of Wind-Induced Conductor Loads
A 161 kV steel pole line in Omaha, Nebraska, is instrumented to provide conductor load field data due to climatic events. Various transducers and monitoring equipment used for data acquisition...
Design of Drilled Piers Subjected to High Overturning Moments
The results are presented of a research study directed at improving the state-of-practice, and resulting foundation economy, in the design of laterally loaded drilled pier foundations...
Strength Data Base for LRFD of Transmission Lines
Reliability-Based Load and Resistance Factor Design (LRFD) has been proposed as a desirable alternative or a complement to the National Electrical Safety Code (NESC) for the structural...
Adfreeze Strength of Ice to Steel Pipe Piles as a Function of Temperature
A study was initiated to determine the adfreeze bond strength between steel pipe piles and freshwater ice as a function of temperature. Tests were conducted at an average strain rate of...
Iceberg Impact Load on a Gravity Based Structure
The mechanics of the eccentric collision of an iceberg against a fixed, rigid, gravity based structure are discussed. A closed form solution is derived for the case of infinite friction...
A Self-Refrigerated Gravel Pad Foundation for Large Thermal Loads
Design criteria for a proposed power plant at Thule Air Force Base, Greenland, involved both large thermal loads from the diesel engines and large static loads from an eight foot thick...
