Reliability-Based Expert Systems for Optimal Maintenance of Concrete Bridges
In this paper ongoing research in the CEC supported BRITE/EURAM project P3091 is presented. In the project reliability based expert systems for inspection and maintenance of corroded reinforced...
An Information System on the Performance of Suspension Bridges Under Wind Loads
While most suspension bridges for which information is available, in operation between the period: 1701-1992, have performed satisfactorily under wind loads, a few bridges were destroyed,...
A Reduced Order Model for the Seismic Analysis of Building-Soil Systems
A finite element based, reduced order, numerical model has been developed for the nonlinear analysis of building-soil systems. The reduced order system model employs an equivalent continuum...
Simplified Reliability Analysis of Transmission Structures Including Both Geometric and Material Nonlinearities
Generally, in nonlinear structural systems, the g-functions of the components cannot be explicitly expressed in terms of the basic random variables. In using the design point method to...
Modal Failure Probability and System Performance
It is pointed out that the modal failure probability, i.e., the probability that a structure fails in a particular mode, cannot be uniquely defined under the time-invariant framework....
Causal Probabilistic Networks in Assessing the Vulnerability of Existing Buildings
A probabilistic assessment of the 'state of health' of the structure is pursued on the basis of pieces of evidence collected by inspection and by querying, in case, historical data bases....
A Prototype Expert System for Rapid Visual Screening of Seismically Hazardous Buildings in California
A rapid visual screening expert system, California Rapid Building Seismic Evaluation Expert, was developed to enable efficient and effective identification of seismically hazardous buildings...
Fatigue Reliability of Structural Systems Under Earthquake Loads
The authors have develop a methodology for calculating the expected low-cycle fatigue damage in structural components subjected to brief nonstationary random loads. The methodology is...
Built-Up Compression Members for Noval Structural Systems
This paper discusses built-up compression members used in novel structural systems for two high-rise buildings: InterFirst Plaza at Dallas Main Center and Columbus Center in New York....
A New Theory of Built-Up Columns
In laced, battened and other built up columns the shear stiffness of the web can have a significant effect on the overall buckling load. At the present time, such columns are analyzed...
QST Rolled Shapes, a New Generation of HSLA Compression Members
With the development of the Quenching and Self-Tempering (QST) process by the Luxembourg steelmaker ARBED S.A., a new generation of High Strength Low Alloy (HSLA) rolled shapes has become...
Loma Prieta Response of an Eccentrically Braced Tall Building
Acceleration response records obtained during the October 17, 1989 Loma Prieta earthquake [Ms = 7.1] from the 47-story, eccentrically braced Embarcadero...
Monitoring Performance of Full Scale Structures
General Physics Services Corporation (GPSC) of Columbia, Maryland has developed a device for the remote long-term monitoring of full scale structures, such as highway bridges. This patented...
What Attributes Should the Structural Engineering Graduate Possess?
This paper will discuss the need for structural engineering students to be trained to think in terms of the performance of the structural system as a whole, rather than the individual...
Twin Lakes Enlargement and Rehabilitation
The Twin Lakes Enlargement and Rehabilitation Project involves an enlarged embankment replacing a two-tiered reservoir system with a single, larger-volume reservoir and new appurtenances....
Rehabilitation of Plane Nine Dam
Plane Nine Dam, an earthen water supply dam near Altoona, Pennsylvania, was constructed in 1907. The dam performed satisfactorily for more than 80 years but it deteriorated with time and...
Seismic Safety Modification of an Old Earthfill Dam
Chollas Dam was built as a water supply reservoir for the City of San Diego. The reservoir is no longer a part of the municipal water system but has been operated since 1966 as a recreational...
IVHS: The Invisible Revolution
Federal funding for intelligent vehicle highway systems has increased a hundredfold since 1989, from $2 million to almost $200 million. Transportation planners are looking increasingly...
Preliminary Assessment of Fault Rupture Hazard at the Yucca Mountain Site Based on Expert Judgement
The judgments of seven earth science experts were elicited to quantify the uncertainties associated with the likelihood of fault displacement through the proposed repository at Yucca Mountain...
The Development of the CRWMS Transportation System
The Transportation System of the Civilian Radioactive Waste Management System (CRWMS) is being developed using a system engineering approach to ensure it is properly integrated into the...
