Data Collection and Information Dissemination: Current Efforts and Challenges
The need for the civil engineering community to collect and disseminate information on failures has been discussed widely. It appears that in recent years our profession's reluctance to...
Integration of Project & Business Planning
An annual business plan is an important document. The process of developing a long term strategy and the concrete action plan necessary for its implementation involves management analysis...
An Analysis of Traffic Signal Safety Improvements
Identifying high accident rate locations and determining that they have an overrepresented type or pattern of accidents is an important first step in the safety improvement process. However,...
New Techniques in Forced Vibration Testing
Forced vibration testing is a well established technique as indicated by references 1 to 8. This paper describes a system for forced vibration testing developed over two years during work...
Sequential Earthquake Response of an Earth Dam
Sequential earthquake-response records of the well-instrumented Long Valley earth dam (Mammoth Lake area in California) are analyzed and engineering interpretations are made. The dam,...
A Critical Look at Building Instrumentation in Earthquake Engineering
This paper discusses different issues and requirements existing in the area of building instrumentation. Strategies and types of equipment currently being used by the United States Geological...
Building Records from 1984 Morgan Hill Earthquake
The dynamic response of 23 structures instrumented by the California Strong Motion Instrumentation Program was recorded during the magnitude 6. 2 (ML) Morgan Hill earthquake of 24 April...
Response of the San Juan Bautista 156/101 Bridge to the 1979 Coyote Lake Earthquake
Strong-motion accelerograms are used to examine the response of a multiple-span highway bridge to earthquake loading. Estimates of modal frequencies and damping values for the first two...
Problems of Spectral Analysis in Dispersion Tests
The use of dispersive surface waves and spectral analysis methods is new to the nondestructive testing of airfield pavements. Such tests are to determine whether mechanical properties...
Research Topics in Structural Identification
The authors examined a variety of possible research topics including identification and detection of nonlinearities, model improvement approaches, damage identification, power estimation...
Rigid Body Random Rocking Prediction
The stochastic rocking of a rigid block due to shaking of its foundation is examined. The foundation is flexible (Winkler) and its independent springs and dashpots separate from the block...
Comparison of Predicted and Measured Dynamic Behavior of Allied Bank Plaza
Structural engineering aspects of a monitoring program to measure Allied Bank Plaza tower's dynamic response to wind are presented. In particular, field data developed during...
Planning for Deep-Draft Navigation Channels
This paper summarizes the trends in seaboard trade, the major commodities for the world, and the share captured by U. S. ports. The discussion includes the new developments of port planning...
Tiebacks for Bulkheads
Tiebacks were once used primarily to support temporary structures such as supported excavations. However, the use of tiebacks has been gradually expanded to include the support of permanent...
Forensic Engineering
Learning from Failures
The activities and qualifications of the Forensic Engineer are summarized in the nine papers published in this book. Procedures for failure investigation are discussed along with failure...
CAD Goes into Analysis
In the past, computer analysis of a design was always a separate and distinct step from CAD. Now, an increasing number of systems are combining the two. One system, SSCAD, allows the engineer...
Interpretation of CPT Data for Design of Earth Dams Near Tehachapi, California
The Static Cone Penetration Test (CPT) was used to obtain needed geotechnical information for design and construction of two small earth dams near Tehachapi, California. The basic CPT...
Comparison Between In-Situ Test Results
Penetration tests provide a means of obtaining data from which estimations can be made of the bearing capacity, settlement and liquefaction potential of the soils tested. Empirical formulae...
Co-ordinated Microcomputer-Based Rain Data Network and Modeling Environment
A co-ordinated microcomputer controlled rainfall collection network has been designed which includes drop counting precipitation sensors, tipping bucket raingauges, Z80-A microprocessor...
Linking Data Base Management and Computer Models
Storing, tabulating, and graphing large volumes of data, not usually a strong point of a computer model, is more appropriate for a data base management system. A blend of these two technologies,...
