Two built-up wide-flange beams with several large holes in each
beam were tested to failure. Strains were measured by strain gages
at various levels, located at the ends and center of typical holes, and
deflections were measured optically at two points on each beam.
Lateral bracing was provided to prevent...
A method of analysis of arbitrarily shaped prestressed concrete
members for biaxial bending is given. The stress-strain curve of
the concrete is represented by two parabolic segments, and the
effects of strain hardening of the steel are included in the analysis.
An iterative numerical procedure is used to solve for...
This paper presents an application of the wave equation to the
problem of selecting a driving hammer for prestressed concrete piles.
The potentially damaging effects of these types of hammers on various
prestressed concrete piles were analyzed by means of parametric
studies carried out on a hypothetical group of problems...
