Full-Scale Measurement on Chiba Port Tower
Chiba Port Tower is a tall tower, 125m high, with a rhombus shaped plan. All of the surfaces are covered with half mirror glass. On the top of the tower, a 'Tuned Mass Damper'...
Unsteady Aeroelastic Base Moments on a High-Rise Building
To consider aeroelastic instabilities of prismatic structures in winds, i.e., vortex induced vibrations or galloping oscillations, unsteady aeroelastic forces must be investigated as the...
Pressure Measuring System for Wind Loads
A project to acquire wind and building surface pressure data in the field is continuing at Texas Tech University. A test building of dimensions 30 ? 45 ? 13 ft (9.1 ? 13.7 ? 4.0 m) and...
Pressuremeter Evaluation of Glacial Till Bearing Capacity in Toronto Canada
Glacial tills were evaluated at three Toronto sites, using conventional methods, the pressuremeter and full scale caisson load tests. The geologic environment and specific subsurface conditions...
Location of Geologic Discontinuities by Geophysical Techniques
An overview of the seismic refraction method and resistivity methods is given. These two geophysical techniques are integrated into a systematic method for locating geologic discontinuities...
Some Dilatometer Test Results in Pennsylvania and New York
This paper starts with a brief introduction to the dilatometer and piezoblade. Test results in four different areas are presented. DMT soundings at LR 67057 (Legislative Route numbers...
Settlement Characteristics from Insitu Tests in Flyash Structural Fills
Flyash from the Baltimore Gas and Electric Company's plants was used to construct structural fills in thickness ranging from 5 to 25 feet (1.5m to 7.6m). Several warehouses...
Pile Foundation Construction Practice in Stiff Clays with Dense Granular Layers
A survey was conducted recently in conjunction with a project located in the San Francisco Bay Area to ascertain the general pile driving practice in stiff overconsolidated clays interbedded...
Management of Drumstick Barrier Islands
Three major problem areas exist on these barrier/inlet systems: 1) the updrift inlet which tends to migrate and erode the upland barrier, 2) the narrow, low and sediment-starved downdrift...
Sediment Transport Processes at Sandbridge, VA
Sandbridge Beach is a primarily residential community located along a 7 km reach of narrow barrier beach. Rates of erosion in this area historically have been high, reaching as much as...
Low Cost Wave Measurement Program
This paper addresses some problems related to a wave measurement program in the coast emphasizing costs, environmental hazards and technological problems. Subjects covered include coastal...
In Situ Determinations of Dispersion and Transport Parameters at Piraquara De Fora (RJ)?Brazil, With Help of a Fluorescent Dye Tracer
This paper deals with 'in situ' determinations of the transport and dispersion parameters at Piraquara de Fora cove, near the site where the first Brazilian nuclear...
Recent Erosion in the Stable Ipanema-Leblon Beach in Rio De Janeiro
This paper presents the findings of a diagnostic study contracted by the City Hall of Rio de Janeiro, concerning beach erosion problems. It first reviews the problem and existing data....
Estimating Soil Gas Flow Rates and Identifying Entry Routes in a Dwelling Using Multiple Perfluorocarbon Tracers
Passive monitoring of indoor air and below basement floor (subslab) soil gas for radon and perfluorocarbon tracer (PFT) gas concentration was conducted to investigate the influence of...
Indoor Radon: Site Evaluation
The soil parameters most important in evaluating the indoor radon potential of a building site are the soil radium concentration, the soil-gas radon concentration and the permeability...
Mass Balance Analysis of Decomposed Refuse in Laboratory Scale Lysimeters
Decomposition of shredded municipal refuse was studied under laboratory conditions with leachate recycle and neutralization. Cellulose and hemicellulose accounted for 91% of the methane...
Effect of Flow Conditions on Stream Reaeration Coefficients
Contrary to the findings of previous studies of channel-controlled stream reaches, it was found that, in four reaches of a small stream characterized by a series of pools and riffles,...
In Situ Measurement of Preferential Flow
An experiment was performed that quantifies the variability of flow paths in the vadoze zone. Bromide tracer and an organic dye, which has many of the same transport characteristics as...
Drought Investigations by the Use of Maximum Daily Temperatures
By the use of maximum daily temperature data, drought events can be defined by taking a certain truncation level to form the partial drought duration series. A drought series representing...
The Alabama Rainfall-Runoff Model, ARRM
ARRM consists of a conceptual state-space model which is cast in a stochastic framework. It uses the W.H. Green and C.A. Ampt method for infiltration, exponential decay for interflow and...
