A Dome For the 21st Century
Putting a circular dome on a square building--the classical architectural design challenge--takes on new proportions at the Federal Building and Courthouse in Charleston, W. Va. The 170...
Preserve and Protect
Historic and landmark structures constructed of unreinforced masonry and stone are among the most vulnerable to strong ground shaking and are often subject to possible collapse. For the...
Design of Mat Foundation for Egg Shape Digesters
Two levels of ground motion, the Maximum Probable Earthquake and the Maximum Credible Earthquake, were considered in designing the 2.5 million gallon egg shape digesters and their combined...
Nonlinear Collapse of Offshore Jacket Structures
The Joint Industry Tubular Frames Project was established with ten oil industry sponsors to investigate the reserve and residual strength of frames typical of offshore structures. To date...
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....
U.S. / Japan Large Scale Cooperative Research Program for Steel Structures
The US/Japan Cooperative Research Program Utilizing Large Scale Test Facilities for Earthquake Resistant Design was initiated in 1980 using a combination of full-scale, small-scale, subassemblage...
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...
Composite Walls as Shear Elements in Tall Structures
This paper describes a system of composite walling that can be used as a lateral load resisting system in tall structures. The composite walling comprises two skins of profiled steel sheeting...
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...
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...
Making an Olympic Stadium and a Baseball Park
A new dual-purpose stadium which reflects not only the classical origins of the Olympic Games, but also the tradition of baseball, is the architectural centerpiece for the 1996 Centennial...
Qualification System for Building Engineers in Japan
Recently, it has become common for structural engineers to provide consulting services beyond their countries. Thus it is important that they become fully acquainted with the working conditions...
Qualification System for Building Engineers in Korea
This paper introduces and discusses the qualification system for professional engineers in Korea which was first established thirty years ago under the Professional Engineers Act. This...
Steel Compression Member Design in the 1994 Canadian Standard
The 1994 edition of CSA Standard S 16.1-M94, Limit states design of steel structures (CSA 1994) contains explicit methods for computing the compressive resistance of monosymmetric and...
Shock-tested R. C. Slabs: Significant Parameters
Shock-tube tests of plain concrete and reinforced concrete (R. C.) slabs were performed. The influence of free water in concrete pores, emphasized in previous tests at a material level,...
Load Rate Effects on Concrete Compressive Strength
Plain concrete cylindrical specimens from six different concrete mixes, 51 mm in length and diameter, were tested in compression quasi-statically at strain rates between 10-6/sec...
Impulsive Punching of Fiber-Reinforced Concrete Slabs
The behavior of FRC slabs reinforced with polymeric fibers (polyacrylonitrile fibers PAN) and subjected to impulsive punching is analyzed here in order to clarify to what extent the fibers...
Innovative Design of Steel Gable Frames
Common wisdom holds that conventionally designed gable frames fabricated from rolled sections cannot compete with metal building system frames fabricated from plate and bar stock, from...
