Abstract
Eccentrically loaded structural members and methods of forming the same. The structural members have their compressive loading axes offset from their load central longitudinal axes.
Claims15
An elongated member comprising:
- an elongated body having a load central longitudinal axis;
- a first fitting coupled to a first end of the elongated body for applying a compressive load to said elongated body along a first axis offset from said load central longitudinal axis when not under said compressive load;
- and
- a second fitting coupled to a second end of the elongated body opposite the first end for applying a compressive load to said elongated body along a second axis offset from said load central longitudinal axis when not under said compressive load, wherein said elongated body

An elongated member comprising:
- an elongated body having an outer surface about a central longitudinal axis, said central longitudinal axis being arcuate and said elongated body being arcuate along said central longitudinal axis, wherein said central longitudinal axis is arcuate when said elongated body is not under a compressive load applied at opposite ends of said elongated longitudinal body;
- a first fitting coupled to a first end of said elongated body for applying a compressive load to said elongated body;
- and
- a second fitting coupled to a second end of said ends of the elongated body opposite the first end for applying a compressive load to said elongated body, wherein said elongated body
