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...
The Application of Seismic Isolation to Bridges
Unlike a building application the primary intent in a bridge is to protect the structure below the plane of isolation - the superstructure being relatively rigid to in-plane loads and...
Development of Design Requirements for Seismically Isolated Structures
This paper provides background and describes on-going work by the Structural Engineers Association of California (SEAOC) to develop design requirements for seismically isolated structures....
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...
Recent Developments in Testing Base Isolation Systems
One of these developments has been the ability to test large scale isolation systems using simulated seismic loads. These tests have not only proven the performance and reliability of...
Recent Developments in Isolation Hardware
Most isolation systems have at least two physical components: one specifically intended to add flexibility and the other to control the resulting deflections. However, other elements may...
Seismic Isolation of Nuclear Plants: A World Overview
The French were first to apply seismic isolation to the design of nuclear structures. Two large Pressurized Water Reactor plants (PWR) were isolated; the two unit Koeberg station in South...
Shake Table Testing of a Friction Pendulum Seismic Isolation System
Building models using the Friction Pendulum System (FPS) were tested on the shaking table at the Earthquake Engineering Research Center of the University of California, Berkeley. This...
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...
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...
Ponds and Lagoons of Gulf Islands National Seashore
A physical and natural resource survey was conducted of the ponds and lagoons on Horn and Petit Bois Islands, Gulf Islands National Seashore, Mississippi. Petit Bois Island contains 17...
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...
Status of the Spiny Lobster (Crustacea: Palinuridae) Stocks Off Northeast Brazil in Relation to Fishing Effort and Environmental Conditions
Conditions for the development of relatively abundant populations of spiny lobsters of genus Panulirus, mainly P. argus and P. laevicauda, off Northeast Brazil are consistent with hydrologically...
The Geographical Information System of the Brazilian Coastal Management Program
The paper discusses the coastal management program presents; and two modules which are intimately associated and integrated with the system of geoenvironment information: the Zoning and...
Tourism Versus Conservation in Fernando De Noronha Island, Brazil
Conscious of the problems created by tourism expansion and searching for a definition of the uses compatible to the restoration and the maintenance of ecological equilibrium, the previous...
Impact on a Primitive Fishing Community in Maric? County, Caused by Urbanization
The fishing communities studied in this paper, although influenced by the more important urban growth movement of the metropolis of Rio de Janeiro, have reacted in a different manner to...
