Structural Engineering and Microcomputers
This publication contains five papers on the use of microcomputers by structural engineers. The first paper discusses the design of multi-story rigid steel frames. The design process employed...
Building Constructed Up and Down at Once
The One Westwood Building, now going up in Los Angeles' suburban Westwood, is being built up and down from ground level simultaneously. The key was a slurry wall surrounding...
Building Frame Analysis in Basic
Moment distribution has, for the past 30 years, been the most popular method of analysis for statically indeterminate structures. Programmed in Basic for the microcomputer with relative...
Methods for Improving the Seismic Response of Concentrically Braced Steel Frames
This paper briefly reviews various factors contributing to the poor performance occasionally observed in concentrically braced steel frame structures during recent earthquakes. Several...
Applications of Fiber Bundle Model to Structural Engineering
The bundle failure time has been studied extensively for both deterministic and random loads. The objective of this paper is to apply results in these studies to the dynamic analysis of...
Code Designed Steel Frame Performance Characteristics
Three similar steel ductile moment-resisting frame structures designed in accordance to the Uniform Building Code (1976-1985) are evaluated for their performance characteristics during...
Prediction and Measurement of Wind Response: Case Story of a Wind Sensitive Building
The wind-induced horizontal accelerations of a 43 story office tower in New York City were monitored during 11 occasions over a period of about six months. The building dates back to the...
Flexibly Connected Thin-Walled Steel Frame Response
The static response of flexibly connected plane frames composed of thin-walled steel members is presented. Analysis capabilities include post-local-buckling strength and elastic semi-rigid...
Multiple Bolt Row Moment End-Plates
This paper presents a portion of the results of a study to develop design procedures for the extended, multiple row, moment end-plate configuration. This configuration is used in steel...
Behavior and Design of Semi-Rigid Composite Frames
Recent advances and experimental research on the behavior of composite semi-rigid frames indicates that substantial savings can be achieved with this method of construction. The current...
On Steel Connection Data Bank at Purdue University
The aim of the establishment of the steel beam-to-column connection data bank program at Purdue University in 1986 was to provide the necessary data base for the determination of the moment-rotation...
Moment Rotation Curves for Double Framing Angles
Moment-rotation curves for bolted framed steel connections are derived from force-deflection data obtained from laboratory tension and compression tests of angle segments. These derived...
Practical Analysis of Flexibly-Connected Building Frames
Modeling of flexible connection behavior as elastic-perfectly plastic is proposed for analysis of building frames, and results based on this idealization are compared with fully non-linear...
Frame Stability
The Chapter on Frame Stability of the Fourth Edition of the SSRC Guide provides guidance on use of several stability design procedures. These include Critical Load Concept, Second-Order...
Applied P-Delta Methods in the Design Office
At first glance some axioms of a P-Delta analysis appear to be paradoxical. First, the P-Delta effects are a direct function of the depth of the structure parallel to the wind direction....
Practical Application of PR Connections and Second Order Analysis
In the present LRFD Specifications type PR (Partially Restrained) connections are described as those where the connections of beams and girders possess an insufficient rigidity to hold...
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...
Second Order Analysis of a 47-Story Building
A modern day second order analysis and ultimate strength review is made of a hypothetical 47-story unbraced frame designed under the 1969 AISC Specification. The original design is part...
Frame Stability - A Canadian Designer's Approach
The deficiencies and fallacies of the simplistic effective column length approach to frame stability are demonstrated through its application to a 57-story rigidly framed building structure....
The Just-in-Case Factor
Computer analysis allows bridge designers to take a more precise look at the old structural principle of redundancy. No one can define redundancy, but everybody knows what it means. Two...
