A Primer on Micropiles
A major study of micropile technology has recently been funded by the Federal Highway Authority and completed by the authors. The subject is defined as a drilled and grouted, cast-in-place,...
Reliability and Response Control of R/C Buildings
A damage model is summarized for the assessment of seismic damage of reinforced concrete structures. The model is to evaluate specific buildings that were damaged in Mexico City during...
Checking Concrete Growth
When the Tennessee Valley Authority built its dams in the 1930s, instrumentation installed in the massive concrete detected a defect that would later cause major problems: concrete growth...
For the Realization of Lunar Concrete
Since most of the raw materials required to make concrete exist in lunar rocks and soils, concrete is considered as one of the most suitable materials for lunar structures. Author's research...
Production of Lunar Concrete Using Molten Sulfur
A study has been undertaken by the authors and supported by NASA to study the feasibility of using lunar regolith with different binders such as molten sulfur, epoxy or hydraulic cement...
Concrete Buildings in Regions of High Seismicity
Structural systems for multistory concrete buildings in regions of high seismicity are reviewed. The suitability and certain practical aspects of the systems are discussed. A Uniform Building...
High-Strength Concrete Columns in High-Rise Buildings
Strength and ductility of high-strength concrete columns were investigated by examining available test data. The results are summarized in terms of load and ductility capacities of columns....
Coupling Translation and Rocking Motions
In the design of concrete block foundations for rotating and reciprocating machines, it is important to avoid resonant conditions. Therefore, accurate determination of the frequencies...
Physical Model Tests of Dolos Impact Stresses
An on-going experimental study to determine impact stresses and static nesting stresses in instrumented large scale model dolosse is described in this paper. Seven dolosse were instrumented...
Corrosion Resistant Epoxy-Coated Reinforcing Steel
Research conducted in the 1970s to evaluate and develop criteria for nonmetallic coatings to protect steel reinforcing bars embedded in concrete bridge decks from the corrosive action...
First Bank Place: A Composite Cruciform Spine
The First Bank Place, designed by the internationally known architectural firm of Pei Cobb Freed and Partners, is a granite-clad, 56 stories tall building in downtown Minneapolis. Presented...
Application of Concrete-Filled Steel Tubular Columns in Tall Buildings in Earthquake Area
In this paper an outline is given of the background, the design concept, structural features, construction and economy of the concrete-filled steel tubular coumns of tall buildings in...
Lateral Bracing Criteria of the Composite Braces
In order to simplify the hysteretic characteristics of diagonal steel braces, a lateral bracing problem of unbonded braces embedded in the concrete panel is treated here. Lateral bracing...
Recent Developments in Seismic Response of Composite Structures
Lack of sufficient data has limited a wider application of structures using mixed steel-concrete construction in seismically active regions. This paper summarizes some recent studies at...
One Peachtree Center: Atlanta Georgia
Presented in this paper are the architectural and structural concepts of One Peachtree Center built in the city of Atlanta. This 62-story tall building has changed the downtown skyline...
One Ninety One Peachtree and NationsBank: Composite Additions to the Atlanta Skyline
The structural design of two composite buildings in Atlanta is described in this paper. A composite exterior partial tube was used in one case and a composite super-column system was utilized...
