spColumn 4.2

spColumn, formerly pcaColumn/PCACOL/IrrCOL, is for the design and investigation of reinforced concrete sections subject to axial and flexural loads. The section can be rectangular, round or irregular, with any reinforcement layout or pattern. Slenderness effects can be considered. The program offers investigation of irregularly shaped, reinforced concrete column sections that may contain openings or boundary elements. You can obtain the P-M interaction diagrams from both uniaxial and biaxial runs, as well as the Mx-My moment contour plots from biaxial runs for even the most irregular column and shearwall sections. Slenderness effects producing magnified moments may be included in the investigation.
