Fretting Corrosion on Large Split Thrust Bearing Runners
In the early fifties interfacial slip was measured on laboratory models. Design improvements, resulting from these tests, were incorporated into later machines. These improvements appreciably...
Our Municipal Water System Has Power
Hydroelectric potential exists in the Boulder, Colorado municipal water system. Excess pressure is developed in the water system because the water originates in the Rocky Mountains, west...
Compaction Characteristics of Roller Compacted Concrete
This paper describes a fundamental study on the compaction characteristics of Roller Compacted Concrete (RCC) in the fresh state during vibration through a laboratory test and a field...
Frequency Domain Site Response with Pore Pressure
A frequency domain analysis for seismic site response and liquefaction potential is developed. The analysis is based upon a nonstationary random vibration theory. The model uses an effective...
A Stochastic Model for Low-Cycle Elastic-Plastic Fatigue Crack Growth
In this paper a stochastic process approach is considered to represent the random nature of the low-cycle (elastic-plastic) fatigue crack growth process. A semi-Markov renewal model is...
Pore Pressure Development: Probability Analysis
The development and subsequent dissipation of excess pore pressure, p in a soil deposit subject to an external load is examined using probability concepts that account for uncertainties...
A Stochastic Seismological Model in Earthquake Engineering
Recent studies of source mechanisms and wave propagation models enable one to generate strong motions based on deterministic source and source-to-site characteristics. The normal mode...
Autoregressive Model of Spatially Propagating Earthquake Ground Motion
An autoregressive random process model was used to investigate a simulation method of spatially and temporally variative ground motion when characteristics of motion are prescribed by...
Time Series Analysis of Wind Pressures on Low Buildings
A new methodology for the description of local wind pressures on the building envelope of mono-sloped roof buildings by using time series analysis is described. A simple AR(1) model has...
Pressures on Prisms in Turbulent Shear Flows
Experimental results are presented which show that Melbourne's 'Small Scale Spectral Density Parameter,' S, controls the negative pressures on the...
Effect of Air Gap on Platform Reliability
A simplified reliability study of the effect of lateral wave forces impacting the deck of a fixed platform is presented. The reliability of the deck legs, considered the primary resistance...
Water Distribution Network Calibration Considering Multiple Loading Conditions
Through time a water distribution network's carrying capacity is reduced as material collects on pipe walls. The impact varies with each pipe in the system and occurs at an...
Towards a Better Simulation of Sea States for Modelling of Coastal Structures
In the last fifteen years, techniques of wave generation have advanced to such an extent that it is now possible to exercise controls of parameters such as wave grouping, wave asymmetries,...
Reef Breakwater Response to Wave Attack
A method of predicting stability of a class of low-crested rubble mounds referred to as reef breakwaters is presented. Findings are based on a study which included an extensive series...
Rock Armouring to Unconventional Breakwaters: The Design Implications for Rock Durability
This paper identifies the need for quantitative durability testing of rock for use on dynamically stable rock armored slopes. The derivation and use of a suite of engineering tests for...
Reshaping Breakwaters on the Stability of Roundheads and Trunk Erosion in Oblique Waves
The stability of a berm type breakwater (sacrificial breakwater) was tested in a 3-dimensional model at The Hydraulics laboratory, Department of Civil Engineering, University of Aalborg....
Hydraulic Performance of Berm Breakwaters
In recent years, the concept of unconventional rubble mound breakwaters, i.e berm breakwaters, has gained much attention among researchers and engineers as an economical method to build...
Application of Computational Model on Berm Breakwater Design
The development of a computational model on dynamic stability is summarized. The model is able to predict profiles of slopes with an arbitrary shape under varying wave conditions. The...
Experimental and Historical Verification of the Performance of Naturlly Armouring Breakwaters
A series of hydraulic model test were carried out to investigate the mechanism by which naturally armoring breakwaters, that is breakwaters in which the initial profile is adjusted into...
Performance of a Berm Roundhead in the St. George Breakwater System
A new harbor under construction on St. George Island in Alaska's Bering Sea is using the berm breakwater concept for protection from wave attack. Three breakwaters are included...
