CAD PACKAGE FOR DESIGN OF RCC COLUMNS

Abstract

Generally design pakcages ofRCC columns based on assumption of neutral axis, neither consider biaxial slender column nor braced case of column. This is due to the fact that analysis of biaxial slender column is quite complex. Design charts of SP:16 tackle this problem with less difficulty. That's why it's a popular tool in designer community. A package based on design charts need inclusion of the charts in program and program-ming of an input device either keyboard or mouse to enter the value from design charts. In the present work, a software based upon design requirements of IS: 456 and SP: 16 design charts has been developed. Limit state method of design was chosen for the work. Software is user friendly and provides a pleasent environment for programming. Graphics and sound were used to create desired effect. After deigning the section software draws a cross-section of it. The major hurdle was to develop a methodology to read data from design charts. This was overcome, by first digitzing the charts and then their programming in graphics mode to display it on monitor. To read data from these charts programming of mouse was done. Mouse programming is a new feature of present work. It was being done with the help of low level programming facilities of 'C' language. Software was developed- on Turbo C compiler on DOS . platform. Comparison of results of solved examples of standard books and results from software validates the effort of present work.
