Hi , im working on my thesis and i need a program that can give me moment curvature diagrams of columns and beams, i have already seen SAP2000 and Etabs section design , but it doesn't gives me much confiant results, as i want a model with confined concrete , i read about XTRACT but i couldn't find it on the web (pay or cracked) , does any one has another program that does this (or if you have the XTRACT program if you can give me the download link i would be very thankful).
