Time-related Deflections of Cantilever Bridges
Many prestressed concrete bridges with spans between 100 and 160 m have been built in the Netherlands. The method of construction is the so-called in situ free cantilever construction....
Automatic, Remote, Multiplexed Geotechnical Measurements with Time Domain Reflectometry (TDR)
Time Domain Reflectometry (TDR) has been employed successfully in geotechnical applications such as monitoring of rock mass deformation in a variety of geometries; however, required operation...
A Computer-Integrated Approach to Teaching Engineering Mechanics
A brief survey is first presented of the evolution of computer hardware and the effect of that evolution on structural software applications and development during the past forty years....
Application of OOP and GUI to the Development of Educational Software in Structural Mechanics
A pilot project on the development of educational software in structural mechanics is reported herein. A computer program for the demonstration of shear, moment, and deflection diagrams...
Teaching Soil Mechanics Laboratories with Computer Assistance
This paper discusses the methods involved in teaching the laboratory section of an undergraduate course in soil mechanics using computer assistance. The lab covered one semester with students...
Practical Solution of the Flexibility to Stiffness Transformation Problem With a Mathematical Assistant for the Personal Computer
This paper will show how a relatively complicated structural mechanics problem can be solved easily with a symbolic manipulation program. Specifically, the authors will demonstrate how...
Computer-Assisted Instruction in Civil Engineering
Computer-assisted instruction (CAI) software offers several advantages over traditional classroom instruction which makes it a useful addition to any curriculum, and the area is rapidly...
A Real-Time Graphical Interface to a Two-Dimensional Groundwater Flow and Mass Transport Model
This paper describes the implementation of a graphical interface to the U.S. Geological Survey's Method of Characteristics (MOC) groundwater flow and mass transport model....
Finite Strain Consolidation for Vertical Drains
Consolidation equations for vertical prefabricated drains which consider finite vertical strain of the soil are derived. Estimated consolidation times are shorter when finite soil strain...
A Procedure for Predicting Seismic Deformation of Earth Structures
This paper presents an analysis procedure for predicting the earthquake induced displacements of earth structures. The procedure is an extension of the simple Newmark method from a single-degree-of-freedom...
Deformations About Excavations in Highly Stressed Rock
The central business district of Sydney, New South Wales (NSW), is dominated by the Hawkesbury Sandstone, a Triassic sedimentary formation. Measurements have confirmed the existence of...
Assessing Roughing Filtration Design Variables
Rural communities are affected by the surface water treatment rule and are looking for inexpensive filtration options which are easy to operate and maintain. This paper evaluates roughing...
Filtration and Backwashing Performance of Biologically-Active Filters
Before widespread use can be made of biological filters, it is crucial to develop an understanding of the filtration and backwashing performance of these filters. Experimental results...
Optimizing Secondary Clarifier Performance: A Presentation Outline
Optimizing secondary clarifier performance is an activity that involves a consideration of the design, the maintenance, and the operation of the clarifier. Although the basic shape of...
Modeling Full-Scale Diffused Aeration Systems
The purpose of this research was to show the direct relationship of the oxygen mass transfer coefficient (KLaT)...
Adaptive Numerical Methods for Transport Dominated Processes
The numerical approximation of processes of transport and diffusion can be very challenging when the diffusion is small compared to the convection. Standard Galerkin methods need to be...
Reliability and Validity of Modeling Sedimentation and Debris Flow Hazards Over Initially Dry Areas
Extreme floods may inundate populated areas of a river valley that are normally dry. Two-dimensional flow analysis is a useful method for predicting the spatial and temporal behavior of...
A Computerized Open Channel Flow Measurement Device
This is a technical information paper with the intention of introducing a new product. It is not the intent of the author to use this as a marketing tool. However, it is the intent to...
Laboratory and Field Evaluation of Acoustic Velocity Meters
A project is currently underway to evaluate the performance of 27 acoustic flowmeters used at Hoover, Davis, and Parker Dams on the lower Colorado River. Field surveys and laboratory testing...
Mapping 2-D and 3-D Velocity Components in Circular Conduits Using an Electromagnetic Current Meter and a 5-Hole Pilot Probe
The techniques presented in this paper facilitate the visualization of the two-dimensional and three-dimensional flow fields at arbitrary sections in a conduit. They have been used to...
