RCColumn: Analysis and Design of RCC sections under axial compression and biaxial
SP: 16 gives interaction curves for rectangular and circular sections. Moreover,
in rectangular sections, the publication only considers all round bar arrangement
and bars on any two opposite faces of the column section.
This may far from reality in many cases..!!!
We most commonly have L and T shaped columns. Further, shear wall sections are rarely
of rectangular shape. Shear walls are usually constructed around lift wells, or
corners which give a shape of C or L sections. No interaction curve or chart is
available for such cross-sections.
RCColumn generates interaction curves and strength envelopes for any arbitrary section
defined by straight line segments with arbitrary postion of bars. RCColumn uses
Finite Element techniques for obtaining these curves.
RCColumn calculates the ACTUAL NEUTRAL AXIS ANGLE and computes the stress block
Thus, RCColumn helps in the following cases:
Generation of interaction curves and strength envelopes for L and T columns.
Generation of interaction curves and strength envelopes for arbitrary shaped
sections for columns and shear walls.
Make scripts which help generation of a section - parametrize the section.
For example, once a script is made to generate L section, any L section may be generated
by just changing the parameter values in the script - quick generation of sections.
Pre-programmed to generate L, T, Plus, Tube, [, etc shapes for cross-sections.
Computation of actual neutral axis angle allows precise calculation of section
Calculate the actual capacity under bi-axial moments and not by empirical
