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...

Stability and Limit Loads of Steel Space Trusses
An investigation of the behavior of cold-formed steel space truss structures, under the interaction of local, member, and overall buckling is described. A Finite Element computer program...

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...

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...

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...

Taipei Trade
The appearance of this building is remarkable�so were the cost savings. A design change form rigid shear walls to a ductile frame helped keep construction of Taipei's World...

Terrain Analysis From Space Shuttle Photographs of Tibet
Several Space Shuttle missions obtained false color and large format, high resolution, black and white stereo photography at an approximate scale of 1:800,000. In addition to available...

Interactive Computer Graphic Seismic Design of Frames
An interactive computer graphics approach for earthquake resistant design of two and three-dimensional steel frames is presented. Analysis and design are possible from code-related equivalent...

Interactive Structural Analysis and Steel Design on the Macintosh
A program has been written for the analysis of two-dimensional structures for the Macintosh personal computer using the Microsoft Basic language. The program takes advantage of the special...
