ASCE Salary Survey 1989
The 20th biennial ASCE salary survey of the engineering profession conducted by the ASCE Committee on Employment Conditions during the fourth quarter of 1989 is presented. It consists...
More Than a Public Hearing
Too often, required community input is reduced to the sometimes dreaded public hearing. Many formal public-involvement programs are comprised of no more than this minimal, yet essential,...
Recent Lifeline Seismic Risk Studies
This monograph is a collection of four papers presented at the 1990 Annual Civil Engineering Convention and Exposition in San Francisco, California. The papers summarize seismic loss and...
Load-Permit Truck Operations in New York State
This paper presents the results of a survey of indivisible-load permit vehicle operations in New York State. The survey was conducted in the context of an investigation into the impacts...
Limit State Analysis Correlated to a Full Scale Tower Test
A Limit State analysis technique has been developed for evaluating the structural capacity of lattice steel electrical transmission towers. The tower strength is determined by using a...
The Validation Problem?Historical Developments
Validation of a probability consists of the estimation of the reliability of the probability. Validation is important when probabilities are based on data, rather than theoretical exercises....
Remote Automatic Data Acquisition Systems
Personal computers have been used on two projects to monitor peformance of structures in an automatically triggered mode. In both cases a local PC is used to continually monitor a triggering...
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...
Instrumentation of the Shenyang T.V. Tower
The recently-completed Shenyang radio and television tower provides a unique opportunity to obtain comprehensive measurements of the along-span variation and coherence of wind-induced...
Reliable Displacements from Integrated Quick-Release Accelerograms
A new baseline correction method has been developed which allows accelerograms collected during quick-release tests of full scale structures to be doubly integrated to displacements. The...
System Identification of Meloland Road Overcrossing
The Meloland Road Overcrossing (MRO) is a two-span reinforced concrete bridge structure located east of El Centro, California, 0.3 mi from the Imperial Fault. The Imperial Valley Earthquake...
System Identification of a Large Structure Using Pseudo-Dynamic Test Data
This paper deals with structural modeling and the determination of optimal nonlinear models by applying system identification techniques to inelastic pseudo-dynamic test data from a full-scale,...
Modal Parameter Identification of an Offshore Platform from Earthquake Response Records
The Whittier Narrows earthquake on October 1, 1987, was recorded by the earthquake monitoring system on an offshore platform installed in a water depth of 97 m in the Santa Barbara Channel....
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...
Seismic Instrumentation of Buildings in Italy
The paper describes the philosophy of the ENEA project of seismic instrumentation of buildings in Italy and the steps made to implement it. The philosophy is twofold: i) to define a general...
Seismic Evaluation of PG&E Concrete Dams
Seismic evaluation of PG&E concrete dams is an ongoing process. The seismic environment for the dams changes over time because more historical earthquake data is obtained, faults...
Statistical Analyses of Drilled Shaft and Embedded Pole Models
In recent years a significant effort has been made by the Electric Power Research Institute (EPRI) to develop new design models, to collect and summarize existing load test data and to...
Countering Terrorist Threats
Musacchio & Rozen assessed the risks and vulnerabilities to a possible terrorist attack of the data processing center of a large European bank. With the increasing use by terrorist...
