Design of Stay Cables
Cable stayed structures, consisting of slender superstructure, stay cables and pylons are optimal systems for long span structures with regard to design an economy. The important function...
Response of Concrete Filled Grid Decks Under Static Loads
This paper briefly discusses the bending strength and stiffness of concrete filled grid decks that are subjected to static loads. The influence of design parameters (traffic flow direction,...
Developing a New Construction Policy for Bridge Management
The SHRP Program and other rehabilitation strategies are based on extending the life of concrete bridge elements. In the Bridge Inventory are a number of bridges that must be reconstructed....
Nondestructive Inspection of Steel Bridge Members
Assessment of the conditions of an aging population of bridges in order to determine the proper maintenance or retrofit operation is a challenge of great importance to bridge engineers...
Bridge Engineering and Life Cycle Cost
The Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) requires that all Federal Aid projects must 'consider...the use of life-cycle costs in the design and engineering of...
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,...
Damage Estimation of Existing Bridge Structures
During recent earthquakes, severe damage have been reported in many bridge structures. Regardless of many damaged structures, methods to identify damage of structures are still limited...
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...
Recent Successes in Welding Jumbo Shapes
A rather unique structure utilizing jumbo shapes was recently designed and fabricated. The structure was 100% welded according to the specifications for welding jumbo shapes recently developed...
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....
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...
Teaching Structural Engineering in Year 2000
The paper addresses the need for changes in engineering education in order to keep pace with the changes that have and will continue to take place in the workplace. Over the past 40 years...
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...
