Dynamic Field Response Studies and Earthauqke Instrumentation of the Meloland Road Overcrossing
Ambient vibration data was obtained at the Meloland Road Overcrossing near El Centro in California by The California Department of Transportation (CALTRANS) as part of a 1978 Federal Highway...
85 Stories in Kuala Lumpur?The 5th and 6th Tallest Buildings in the World
A concrete core and cylindrical concrete tube structure provides a safe, elegant, efficient and constructible solution to the challenge of designing the world's 5th and 6th tallest buildings,...
Response of Equipment in Structures Supported on Resilient-Friction Base Isolators Subjected to Ground Motion
In this paper, the response of equipment in structures on a particular friction-type device, the resilient-friction base isolator, is examined. The R-FBI is composed of layers of Teflon...
Robust Control for Buildings Under Earthquake
Robust control techniques are applied to civil engineering structures subjected to earthquake excitation. Full state feedback and observer based control laws are used to reduce the response...
Passive Energy Dissipation Systems for Earthquake-Resistant Design
Passive energy dissipation devices, also known as supplemental damping devices, have been proposed as a means by which the earthquake resistance of a building can be substantially enhanced,...
Recent Developments in Seismic Isolation Technology
Large experimental research projects for isolators for both civil structures and nuclear reactor applications have been conducted at the Earthquake Engineering Research Center (EERC) over...
Seismic Isolation Retrofit of the State of California Justice Building
The State of California Justice Building, located at 350 McAllister Street, San Francisco, is the first building to be selected by the State of California for retrofit using seismic (base)...
Seismic Performance of Base-Isolated Building Structures
The theories and assumptions behind the base isolation technology are briefly described. As an illustration of its application, the base isolation of an existing 12-story hospital in Long...
Seismic Base Isolation Design for the San Bernardino County Medical Center Replacement Project
The SBCMC Replacement Project, located in Colton, California, consists of six separate building structures containing a total of approximately 86,000 m2...
Development of Computer-Based Models of Standards and Attendant Knowledge-Base and Procedural Systems
Existing and new technology can be used to develop a new generation of standards that would allow designers to use complex standards efficiently, help standard-writing bodies to detect...
Investigation of Full-Scale Performance of Structures?Research Potentials
It is well known that actual, or true, behavior of completed structures does not necessarily conform to often simplified analysis predictions. This may be due to any of several reasons...
Seismic Strengthening for Structures in Regions of Low Seismicity
Most existing structures were not designed to today's seismic codes and standards, and in fact in low seismicity regions codes did not require seismic design until recently....
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,...
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,...
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....
