Equating Dynamic Analysis to Static Code Provisions
Building codes generally prescribe seismic design provisions that include a static lateral force procedure that can easily be combined with the gravity loads to design the structural elements....
Development of Inelastic Reduction Factors to Provide an Elastic Design Procedure
R factor values can only be rationally selected when they are based on in part nonlinear inelastic dynamic analyses of building system types. However, it is informative to discuss the...
1988 SEAOC and UBC Seismic Provisions
This paper highlights the major improvements to seismic design provisions incorporated in the 1988 Structural Engineers Association of California (SEAOC) 'Blue Book'...
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...
Cracking the Fire Code
Local building codes specify fire resistance for members in buildings and other structures, and structural engineers select materials and assemblies that have passed a standard fire resistance...
The Church on Stilts
Christ Church Cathedral is an Anglican church situated in the heart of downtown Montreal. Constructed in 1859, it is a perfect example of English neogothic architecture, characterized...
Foundations on Expansive Soils in Northern Virginia
Thick layers of clayey silts (MH) were observed at several sites where townhouse developments were planned. These deposits had a high shrink swell potential. Maximum swell pressure tests...
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...
Ground Failure Damage to Buildings During Earthquakes
Several case histories are examined to evaluate building damage as a function of the foundation type and type and amount of ground displacement. Extensional or vertical ground displacements...
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...
Performance of a Building Foundation Designed to Accommodate Large Settlements
The Eastern Airlines shuttle terminal at LaGuardia Airport in New York City is supported on spread footings founded in an incinerated refuse fill which overlies a deep deposit of slightly...
A New Combined Footing and Drilled Shaft Foundation Design
A conventional belled caisson foundation installation in glacial till to support a suburban Chicago 10-story office building was stopped when test caissons revealed excessive water-bearing...
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...
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 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...
Environmental Evaluation of the Coastal Area of Marci? District: A Methodological Essay
This paper is part of an integrated study of the coastal environment of the county of Marica, Rio de Janeiro, where the environmental alterations of the urban expansion phenomenon were...
