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....

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....

Role of Microcompiuters in Highway Weigh-in-Motion Systems
Microcomputer technology makes it possible to digitize the signals, calculate the desired factors, and record and display the information in real time at the weigh-in-motion (WIM) site....

Materials and Member Behavior
Each of the papers in this book covers some aspect of material properties. New developments in cold formed steel are reviewed. The strength, stiffness, and ductility of steel connections...

Dynamics of Structures
