As a result of the need for tunnels, underground highways and parking structures, cofferdams, facilities related to the improvement of the environment, etc., there has been a significant...

Joint Design in Composite Columns/Steel Beam Structures
The use of a composite building system, utilizing a composite exterior column and a concrete spandrel beam system, proposed by Dr. Fazlur Khan in 1967, is recalled. In the last 25 years,...

A Shear Transfer Model for Floor-To-Wall Connections in Concrete Masonry Structures
Based upon experiments conducted at the Univ of California, San Diego (UCSD) on floor-to-wall connections in concrete masonry structures, a constitutive model was developed for the overall...

Analysis of Masonry Walls with Smeared and Discrete Crack Models
To design modern reinforced masonry structures for seismic loads and to evaluate the seismic safety of existing unreinforced masonry buildings, the shear resistance of masonry shear walls...

Dynamic Response of Variable Height Retaining Walls
A full-scale dynamic test was conducted on a 140 ft long reinforced concrete retaining wall. The observed resonant configurations were similar to those of a cantilever plate and showed...

Mud Mountain Dam Concrete Cutoff Wall
Mud Mountain Dam is an earth and rockfill flood control dam on the White River. The dam is located approximately 50 km southeast of Seattle, Washington. The dam was constructed in 1941...

Prestwood Lake Dam Rehabilitation
The Prestwood Lake Dam located in Hartsville, South Carolina is owned by Sonoco Products Co. It originally was a wood structure built in 1895. That structure was washed out by a hurricane...

Rehabilitation of the Deep Creek Lake Dam
This paper presents the rehabilitation design for upgrading the Deep Creek Lake dam. The Deep Creek dam is a rock fill dam, 92 feet (28 m) high and 1290 feet (393 m) long, and constructed...

Drift Emplaced Waste Package Thermal Response
Thermal calculations of the effects of radioactive waste decay heat on the potential repository at Yucca Mountain, Nevada, have been conducted by the Yucca Mountain Site Characterization...

Heat Transfer in Vertical Concentric Cylinders in a High Level Nuclear Waste Repository
Modeling free convection heat transfer in an cylindrical annular enclosure is still an active area of research and an important problem to be addressed in the high level nuclear waste...

Study of a Computer System for Evaluation of Bearing Wall Stresses in Structural Planning — Reasoning by Neural Network
This report proposes a reasoning system for bearing shear wall stresses in the ultimate state by using geometrical data of buildings and shear walls at the initial stage of aseismic structural...

The Force Between a Bogie and a Troubled Suspension and Guidance Coil
It is very important for the superconducting LSM Maglev vehicle to maintain the safety. Currents induced in suspension and guidance coils arranged on the side wall of a guide way generate...

Cumulative Environmental Impacts of Shoreline Stabilization on Puget Sound
Although shore protection structures such as bulkheads and seawalls may provide protection to upland property owners, they bring with them numerous potential adverse environmental effects....

Sand Losses from an Artificially Nourished Beach Stabilized by Groynes
Norderney is one of the East Frisian barrier Islands in Germany. Severe dune erosion jeopardized the settlement and neccessitated the use of seawalls and groynes after 1850. Even though...

New Structures Used for Protection of the Black Sea Coasts
New construction of coastal protective issues, elaborated in SIA Saknapirdatsva are described in this paper: such as two-chamber crib retaining wall, through coast grayne, hollow concrete...

The Azov-Black Sea Coast of Russia—An Experience of Artificial Beach Formation
There is a tendency in modern cost protective engineering to expand the scales of artificial beach formation. The first sandy beach was filled in 1971 in Gelendzhik Bay. In 1982 wide scale...

Sea-Level Rise in Senegal: Impacts and Responses
The potential impacts and responses of sea-level rise on the coastline of Senegal are analyzed with an emphasis on regional distribution. Impacts include loss of land and the economic...

Shore Protection Design—A Necessary Evil
Since much shore protection exists and further shore protection will be considered necessary in the future, this paper addresses the need for better design methods to replace the present...

Pumping or Slurry Walls—Which Works Best for Groundwater Containment?
Results of a numerical optimization model capable of designing containment systems for sites with three-dimensional groundwater flow indicate that site hydrogeology and economic considerations...
