Simplified Steel Compression Member Design
The objective of this paper is to present a simplified method of designing steel columns subjected to axial loads and moments for use in situations where automated design methods are inappropriate....
Beam-Columns
The Fourth Edition of the SSRC Guide presents a state-of-the-art information on beam-columns for use by specification writers, researchers, and designers. The present paper is an extremely...
Effect of Connector Spacing on Double Angle Compressive Strength
The 1986 AISC 'Load and Resistance Factor Design (LRFD) Specification for Structural Steel Buildings' includes new rules affecting the design of built-up members...
Design of Steel Buildings for Second Order Effects
Several methods of calculating corrected effective length factors for unbraced frames are presented and discussed. In addition, an alternate format is suggested for the ASD beam-column...
Reinforced Concrete Column Reliability
A method is proposed whereby the reliability is obtained using the stable configuration approach of structural system reliability. The configurations are defined based on imposed strains...
Concrete Strength Record Jumps 36%
A Seattle building now going up has 19,000 psi concrete, the strongest ever in conventional structures. It costs three times as much as conventional concrete, so will not be widely used....
Rehabilitation of a Pump/Turbine
Between 1964 and 1968, eight 212 in pump discharge diameter Baldwin-Lima-Hamilton vertical pump/turbines with Westinghouse motor/generators were installed in Philadelphia Electric Company's...
Spring Stiffness for Beam-Column Analysis of Soil-Structure Interaction Problems
The objective is to provide a simple means of analytically combining a two-dimensional foundation with a beam-column structure so that the procedure can be used for preliminary design...
Practical Modeling of Bar Slippage in R/C Joints
A procedure based on the displacement method of analysis has been developed for analyzing the behavior of beam reinforcement crossing the interior beam-column connections under seismic...
The Atlantic Palace: Part I Structural System Selection Based on Wind Tunnel Testing
The location of the structure in a coastal area susceptible to high winds, the irregular shape and height of the building and the desire for more accurate wind loading and acceleration...
Postmodern Engineering
Momentum Place is a postmodern skyscraper in Dallas designed by architects John Burgee and Philip Johnson. The Datum-Moore Partnership, structural engineers, designed the structural system...
Long Reinforced Concrete Columns
Papers selected by the Reinforced Concrete Research Council of ASCE. This collection contains 13 papers reporting the results of a series of studies,...
Record High Rise, Record Low Steel
The Bank of China, under construction in Hong Kong, will be the world's fifth tallest building. In spite of the extraordinary codes for that city�high winds, and high live...
Seismic Design of Braced Steel Frames
Seismic behavior of a six-story, K-braced structure without backup ductile moment-resisting frames designed according to the current Uniform Building Code is studied in this paper. The...
China Builds Record Bridge
China's Hanjiang Railway Bridge has a 1,000 ft (305 m) long main box girder and is the longest bridge of its type in the world. The steel box girder bridge is built with a...
Mixing Steel and Concrete
For highrise structures, mixed steel-concrete systems are more efficient and cost less than either material alone. The two design approaches are exterior tube structures and core braced...
Strength of Composite Beams under Seismic Loading
Effective width of a concrete slab of a composite beam is specified in various specifications, but their theoretical backgrounds are obscure. Originally, they must have been specified...
Mixed Systems: Past Practices, Recent Experience, and Future Direction
A comparison is made between composite column capacities derived from the authors procedure utilizing the ACI (America Concrete Institute) code requirements, and previously published semi-empirical...
Recent Research on Composite Structures for Building and Bridge Applications
Continuing research has been carried out at Lehigh University on composite structural members, joints, and overall systems. This paper summarizes the results of research on four selected...
SRC Elevated Station Structures for New Bullet Trains
SRC Steelframe reinforced concrete structures were utilized on several station buildings for the Japanese National Railways bullet trains. This paper presents an outline of the dimensions...
