This investigation attempts to relate the flange slenderness ratio to the rotation capacity of steel wide-flange beams subjected to a moment gradient. The steel used was CSA G 40.12, a...

Reinforced Concrete Beams Under Repeated Loads
This paper describes the results of an experimental program of the effect of repeated loads on the rotation and load carrying capacity of reinforced concrete beams. Comparing results obtained...

Flexibility Influence Functions for Curved Beams
The curve representing the elastic axis may consist of straight sections, curved sections, or both, and may have a locus of points lying in a plane or in three-space. Each differential...

Resilient Ferry Slip with Retractable Fender
The design of a ferry slip using retractable contact frames, moving inward and upward on bearing brackets with tracks of various inclination is described. The rigid frame on which the...

Analysis of Elastic-Plastic Grid Systems
An incremental load method for analyzing the piecewise linear behavior of elastic-plastic grid systems with various support conditions is presented. The assumption is made that the torsional...

Turbulent Helical Flow in an Annulus
Turbulent flow of an incompressible fluid in the annular space between concentric rotating cylinders with an axial pressure gradient is investigated experimentally and theoretically. The...
