Dynamics of Nuclear Power Plant Structures with Foundation Interaction
This paper presents analyses and conclusions pertaining to a recorded earthquake motion felt at a nuclear power plant. The objective is to obtain frequency composition, assess damage potential,...
Monitoring of Structures During Repair of Underground Utilities
A collapse of underground utilities at a power plant required the constant monitoring of the surrounding structures during excavation and replacement of the damaged pipes. A computer-based...
A Study of Jointless Bridge Behavior
The pressing need for maintenance free and low construction cost bridges, has increased the interest and activity in building integral or jointless bridges. The investigation of the behavior...
Overview - Electrical Substation Structures Design Guide
The ASCE Substation Structures subcommittee of the Committee on Electrical Transmission Structures (CETS) is developing a substation structures design guide. The guide discusses the analysis...
Test Experience with Heavy Angle Dead End Lattice Transmission Towers
During the past three years, the Electric Power Research Institute's Transmission Line Mechanical Research Center has conducted full scale tests on three 500kV heavy angle dead end lattice...
Assessment and Upgrade of an Older Transmission Line
This paper discusses the various tools and procedures which have been used to assess and upgrade an older 130 kv tower line. The purpose of the assessment was to determine the line compliance...
ASCE GUIDE for Design of Guyed Transmission Structures
This paper describes the contents of a new ASCE guide for the selection and design of guyed electrical transmission structures. Guyed transmission structures present unique analysis and...
Investigating the Behavior of a Lattice Structural Section
Tests were conducted on a fully instrumented lattice section assembled using various connection types (bolted or welded). The results of this study show that bolt slippage can have a major...
Fatigue Damage Accumulation Under Stochastic Stress Histories
An extensive simulation study was performed to generate random Gaussian stress time histories from power spectral densities (psd's). The psd's of time histories were selected to represent...
Practical Application of Tuned Liquid Damper for Tall Buildings
Performance of TLD, based on the full-scale measurement of an actual tall building, is discussed in this paper. Wind induced vibration of the SYP Tower was measured during a gusty day,...
Control of Random Crack Formation in Portland Cement Concrete Pavements
Random crack formation in concrete pavements, which is mainly due to the development of tensile stress caused by temperature-induced volumetric change and shrinkage deformation at early...
Design and Analysis of the 712 Fifth Avenue Structure
New York City's 712 Fifth Avenue is an extremely-slender concrete tube tower. This text addresses the structure's lateral structural system, wind analysis, computer model, thermal analysis...
Helium-Supported Hangar for a Small Solar-Powered Airship
For the IGA Expo '93 the Institute for Statics and Dynamics of Aerospace Structures, University of Stuttgart, together with Stuttgart Solar e.V. developed a solar-powered airship. For...
Numerical Simulations of the CCS under the Joint Effects of Coastal Geometry and Surface Forcing
Using the S-Coordinate Rutgers University Model (SCRUM) of Song and Haidvogel(1993), a coupled coastal (86 m depth) and deep ocean (4600 m depth) California Coastal region has been investigated...
The TMA Wave-Energy Constraint and Cohesive Shore-Profile Shapes
A relation by Andreanov between wave-energy loss and nearshore slope, when combined with the TMA wave-energy constraint, is shown to closely approximate the classical Bruun/Dean shape....
The Re-derivation of the NDBC Wind-Wave Algorithm
The National Data Buoy Center (NDBC) currently manages a network of 57 moored buoys and approximately 7 Coastal-Marine Automated Network stations on off shore platforms which transmit...
Observations of Wind Wave Growth by ERS-1 SAR
Spatial variations of ocean waves can be observed from space-borne synthetic aperture radar (SAR) images of ocean surface. For a steady offshore wind, the growth of wind wave from an upwind...
Modified Asphalt Binders - How Do They Compare?
This report summarizes some of the research that the US Army Engineer Waterways Experiment Station (WES) has conducted on asphalt modification of airport/airfield pavements. these laboratory...
BPA Realtime Hydrologic Forecasting System for the Columbia River Basin
Bonneville Power Administration (BPA) markets and distributes the hydroelectric power produced at 30 federal projects in the Columbia River Basin. In order to plan the System's coordinated...
Development of Hydro-Scheduling Model for Optimal Joint Operation of Multi-Reservoir Systems
Multipurpose reservoirs in a reservoir system are not limited to supplying ample amounts of water and electricity, but also provide other water demands such as flood control, navigation,...
