Masonry Performance in the Coastal Zone
Investigators from the National Concrete Masonry Association (NCMA) surveyed the coastal areas of South Carolina from Charleston to Myrtle Beach during a seven day period just after hurricane...
Are Timber Seawalls that Fail, Cost Effective??Seacliff State Beach Santa Cruz County, California
Proposed reconstruction of a major portion of a 5,100-foot long timber seawall at Seacliff State Beach in Santa Cruz County, California, in 1984, became a major controversy because of...
Foundations and Breakaway Walls of Small Coastal Buildings in Hurricane Hugo
After Hurricane Hugo a survey of damage to small, coastal buildings was conducted in North and South Carolina. The performance of elevated foundations, breakaway walls and foundation cross...
Beach and Cliff Erosion Processes at Solana Beach, California, 1984-1990
Observations of back beach elevation changes, profiles and cliff erosion over a 7-year period from 1984-1990 provide a detailed local view of these processes and rates at a typical Southern...
Effects of Sea Level Rise on the California Coast
Although California is thought to be an emerging coastline which would be little affected by a change in sea level, a 5 foot rise over the next 100 years could have a significant impact...
The Interaction of Seawalls and Beaches: Four Years of Field Monitoring, Monterey Bay, California
Coastal protection structures have historically been the most common approach to dealing with the problem of shoreline erosion in the United States. Three potential impacts of these structures...
Wave-Induced Scour Prediction at Vertical Walls
Scour at the foot of a vertical wall is examined for the special case of normally-incident, nonbreaking irregular waves that are perfectly reflected by the wall. The bottom is initially...
History of Lysimeter Design and Use for Evapotranspiration Measurements
Lysimeters are devices for measuring percolation of water through soils and sampling soil water for chemical analyses. Lysimeters have been used for over 300 years to determine water use...
Limit States Design of Wooden Formwork for Concrete Walls
Load and resistance factors are developed for ultimate limit states design of wooden formwork components for concrete walls when the lateral concrete pressures are computed using the ACI...
Quake-Safe Housing, Again
Because so little data exist about earthquake behavior of buildings that have been strengthened to meet seismic codes, many engineers are curious about the Hotel Oakland in California...
The Structural Curtain
Curtain walls are not standard off-the-shelf items. For major projects, they are almost always custom-designed. Typically, curtain walls are on the critical path of project and often account...
Structural Investigation of Marina Del Rey Seawall
The Marina del Rey Seawall was constructed by various contractors between 1959 and 1961. It is composed of 660 panels totaling 39,600 linear feet. The seawall configuration is a type normally...
Seismic Fragility Analysis of Shear Wall Structures
This paper presents an analytical method to generate seismic fragility curves for shear wall structures. Uncertainties in earthquake motion and structure are quantified by evaluating uncertainties...
Museum Showcases the Future
On May 4 in Philadelphia, the Franklin Institute's new wing, called the Futures Center, will open to the public. When the institute's neoclassic main buiding...
Modeling of Coupled Heat-Mass-Stress Effects in Geologic Media
To investigate the importance of coupled hydraulic-thermal-mechanical processes for the potential nuclear waste storage repository at the Yucca Mountain, a computer code is being developed....
Measuring Performance of Clay Containment Barriers
Clayey soils compacted to engineering specifications are widely used as structures for hydraulic containment. Current applications include landfill liners, landfill covers, pond liners,...
Access Tube Characteristics and Neutron Meter Calibration
Neutron meter calibration was found to be influenced by material type, thickness and size of access tube. Meter counts were decreased by an average of 15% for a 20% increase in tube diameter...
Channel-changing Processes on the Santa Cruz River, Pima County, Arizona, 1936-86
Lateral channel change on the mainly ephemeral Santa Cruz River, Pima County, Arizona, causes damage and has spawned costly efforts to control bank erosion. Aerial photographs, historical...
Repair of an Improperly Detailed Masonry Facade: A Case History
The masonry facade of an 18-story condominium building was constructed with an inconsistent pattern of shelf angle supports, marginal lateral restraints and without any horizontal control...
Three Tools for Design Test Bed Analysis
Three analytical tools are outlined for use in design test bed work focusing on the design/production interface. The tools are substitution analysis, coupling analysis, and value chain...
