Compressive Deterioration of Cracked Concrete
When shear behavior of reinforced concrete (R/C) members is to be simulated, the compressive strength and the stiffness reduction of cracked concrete must be taken into consideration....
Load and Resistance Factor Design for Engineered Wood Construction
The wood industry has provided sponsorship for the development of a reliability-based, load and resistance factor design specification for engineered wood structures. This user-tested,...
Member Design Equations for a LRFD Wood Specification
A key step in the preparation of a load and resistance factor design (LRFD) based design specification for engineered wood construction is the selection of the behavioral equations for...
In-Plane Behavior of Concrete Masonry Coupled Walls
To study the in-plane seismic resistance of multi-story masonry coupled walls, 6 full-scale reinforced masonry specimens, each two stories high, are being constructed and tested in the...
The Challenge of Yucca Mountain
Yucca Mountain is the most likely site for the nation's high level nuclear wastes. Congress chose the site out of three candidates for further study before designating it...
System Identification of Earth Dams Using Seismic Records
A technique to identify the elasto-plastic dynamic properties of earth dams and, therefore to asses the capabilities and limitation of their models, is developed. The technique is based...
Ductility and Failure Characteristics of Concrete and Rock Subjected to Complex Load Paths
Strength, ductility and the complex material response features of concrete and rock should be evaluated through carefully planned material properties test programs designed to subject...
Seismic Vulnerability and Upgrading of Buildings Geotechnical-Geological Aspects
The effects of local soil conditions on the characteristics of earthquake motions (soil amplification) and on the dynamic response of structures for a given foundation type (soil structure...
Amelioration of Stirrup and Compression Reinforcement on the Ductility of Reinforced High-Strength Concrete Beam
18 rectangular high strength concrete beams were tested to investigate their ductile behavior. The results show that it will be more advantageous, for ductility, to choose the compressive...
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'...
Design and Construction of Stone Column Reinforced Cofferdams
A recent expansion of the North Carolina State Port Facility, at Wilmington, involved the use of six cellular cofferdams as earth retaining structures during dredging and final filling...
Design Methodology for Foundations on Stone Columns
Stone columns offer the geotechnical engineer a valuable and viable technique for stabilizing sites underlain by soils ranging from soft clays to loose silty sands. A discussion of the...
Improving Properties of Active Clay by Sand Admixtures
Characteristics of an active clay under various contents of sand are presented. The sand is an admixture used for improving properties of the active clay deposited at a marginal site....
Concrete Removal Techniques with Potential for Use in Rock
This paper describes concrete removal techniques that were employed in the rehabilitation of US Army Corps of Engineers mass concrete structures and are thought to have potential for limited...
Rock Excavation with Boom Mounted Hydraulic Impact Hammers
A hydraulic demolition hammer mounted on a common backhoe or excavator carrier has gained world wide acceptance in the construction industry as a viable alternative to blasting. This paper...
Rock Excavations in Downtown Toronto
The geology of Toronto area is somewhat complex due to the series of advances and retreats of the glaciers. The overburden deposits consist of materials laid down during the Wisconsinan...
Fracturing of Rock Using Expansive Soundless Chemical Demolition Agents
The theoretical principles of the action of expansive soundless chemical demolition agents are presented. The procedure for using these demolition agents are briefly outlined. Differences...
Rock Excavation with Microwaves: A Literature Review
Research on the use of microwaves for breaking rocks started in the late fifties. In this paper, the principles of microwave heating and the possible mechanisms responsible for the breaking...
Static Behavior of Piles in Cemented Calcareous Sands
A series of instrumented jacked model pile tests and another series of uninstrumented grouted model pile tests in a cemented calcareous sand were performed. The influence of pile installation...
Numerical Modeling of Interface Behavior for Drilled Shaft Foundations Under Generalized Loading
To evaluate soil-foundation interaction numerically, an isoparametric thin layer element is used within a 3-D, material nonlinear, general purpose geotechnical analysis system developed...
