Computer aided design of reinforced concretecolumn subjected to axial compression and bending

In structural design of column,the dimensions of the column and reinforcement are initially assumed and then interaction formula is used to verify the suitability of chosen dimension and reinforcement. This approach necessitates few trials to coming up with and economical and safe design.P-M interaction diagram are given in design aids for analysis and design of column for symmetrical arrangement of reinforcement and limited cover to depth ratio.An attempt has been made in this paper to computerize the design of rectangular and square column section with graphical user interface using limit state method of design.Which facilitates analysis and design of symmetrical as well as unsymmetrical arrangement of reinforcement and also developsinteraction diagram for the section.
