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,...

Tradeoffs Between Active Control and Identification of Structural Systems
This paper explores the tradeoffs between structural identification and structural control in a quantitative manner. Through the intemediary concept of an optimal input, it is shown that...

Biaxial Damage Assessment
The structural system under investigation is a frame subject to seismic excitations. The analysis accounts for the spatial distribution of beams, columns and bracing system. It also considers...

Seismic Isolation of a Flight Simulator Manufacturing Facility
The corporate headquarters of Evans & Sutherland is located in the University of Utah Research Park which is in Salt Lake City, Utah. A major fault runs through Salt Lake City...

Seismic Repair, Restoration and/or Upgrading of Existing Buildings
The ultimate goal of this paper is to discuss the selection of the most efficient (optimal) strategies and techniques for upgrading an existing building. To achieve this goal, it was considered...

Historic Background of Seismic Construction in San Francisco
A seismic design and construction tradition has developed in California because of the unique experience with local earthquakes. After the 1906 earthquake and fire, building performance...

A Geotechnical Analysis System with Applications for Drilled Shaft Foundations
The development and components of a geotechnical analysis system are described and illustrated for drilled shaft foundations. This finite element-based analysis system incorporates several...

Some Expert System Applications in Geotechnical Engineering
Knowledge-based expert systems (KBES) represent a new technology for computer-aided engineering. These systems can be useful in situations which involve expert judgments for effective...

Geotechnical Judgment in Foundation Design
This paper summarizes the initial findings of a research project to investigate the judgment-making process of foundation engineers. Solutions for a typical design problem were solicited...

Performance of a Large Ribbed Mat on Cohesive Soil
The performance of a 678-ft by 304-ft (207-m by 93-m) ribbed concrete mat was studied to provide improved soil input parameters for design. The mat was constructed on a low plasticity...

Thoughts on the History and Current Practice of Foundation Engineering in North America
With the publication of 'Erdbaumechanik' in 1925, the behavior of soils was explained in terms of numerical physical properties and the principles of what became...

Integration of Research Into Design Practice
A widely held perception is that research results flow from the research community along the paths of professional publication into the design offices, where they find practical application....

Patterns of Erosion Along the Atlantic Coast
Shoreline erosion data are needed in the implementation of recent legislation that authorizes the National Flood Insurance Program (NFIP) to provide advance insurance payments for the...

Building on the Coastal Barriers Resource Act
In 1982, the Coastal Barrier Resources Act (CBRA) was enacted to minimize the loss of human life, wasteful expenditure of Federal revenues, and damage to fish and wildlife and other natural...

Coastal Barrier Resources Act Report to Congress
The Coastal Barrier Resources Act (CBRA) of 1982 established a system of 186 coastal barriers along the U.S. coasts of the Atlantic Ocean and Gulf of Mexico, and prohibited within this...

The Coastal Management Program in Brazil
As a proposal to guide the rational utilization of coastal resources, the Brazilian government established the National Coastal Zone Management Plan (PNGC), according to the Federal Law...

Environmental Economic factors of the Southern Brazilian Coast
The goal of this study is a large-scale synthesis of the ecological and economic characteristics of the Southern Brazilian Coast. The coastal area is formed by a watershed, a lagoon, and...

Low Cost Wave Measurement Program
This paper addresses some problems related to a wave measurement program in the coast emphasizing costs, environmental hazards and technological problems. Subjects covered include coastal...

The Coastline of Rio De Janeiro From a Coastal Engineering Point of View
The Ocean Engineering Department of COPPE/UFRJ started in early 1988 a project called 'Littoral Rio', in order to make an assessment of coastal engineering problems...
