The Measurement of Structural Deflections
A basic parameter to be determined when assessing the performance of structures is the stiffness. This involves the measurement of static and/or dynamic deflections at representative locations...

Strong-Motion Records from Buildings
Since the establishment of the California Strong Motion Instrumentation Program in 1972, over 90 buildings have been instrumented extensively to measure their response during earthquakes....

Some Significant Records from Instrumented Structures in California—USGS Program
The main objective in seismic instrumentation of structures is to facilitate response studies that lead to improved understanding of the dynamic behavior and the potential for damage to...

Seismic Instrumentation and Its Implication for High-Rise Buildings in Japan
An outline of the present state of the strong earthquake motions observation systems in Japan and an example of the obtained records of an earthquake and its simulation analysis of a high-rise...

Goods Transportation in Urban Areas
The conference on Goods Transportation in Urban Areas (GTUA V) held in Santa Barbara, California, during March 6-11, 1988, focused on three major themes—truck accommodation in urban areas;...

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...

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...

Preliminary Analysis of Multispectral Electronic Self-Scanning Radiometer Imagery from the Marine Observation Satellite

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...

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...

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...

A Tracer-Model for Morphological Simulations of an Estuary
Numerical models for longterm morphological simulations are traditionally based on assumptions like vertical integration of the flow and transport equations and their decoupled treatment....

Oil Hydraulic Design for Turbine Control
The paper addresses three areas of Oil Hydraulic Design for Francis and Kaplan Turbines: smart accumulator condition sensors, high flow servo logic, and high pressures Wicket Gate cylinder...

Model Tests for Six-Jet Vertical Pelton Turbines for Bradley Lake Hydroelectric Project
A model of a six-jet vertical Pelton turbine, including the spiral distributor, 50 feet of penstock, discharge chamber, and short free-surface tailrace was designed, built, and tested...
