I just wrote some small simple programs in Matlab to calculate and graph the P-M-M curves for a rectangular column subjected to axial force & biaxial bending moments. The design code is Canadian CSA A23.3-04 concrete design. However, it can be readily modified to suit other codes. The prog can draw a series of 3D P-M-M curves (and a 3D surface plot) according to a specified range of angles (i.e. direction of biaxial moment measured against x-axis). You can change column dimensions (Hx, Hy), concrete strength (fc), number of longitudinal bars (Nb = 4, 8, 12, 16....)...or specify a range of angles (at least 3; ex: THETA = 0:pi/16:2*pi or THETA = -pi/2:pi/16:pi/2...) to test it out.
the link below is for the Matlab zip file (colPMMcurves.zip); unzip 4 files into a folder. Run Matlab R2010a and set the above folder as current working folder. From the folder, double-click RcolPM3D_2 (this one is the main script, the other are just functions) to start it. Enjoy! (another prog for circular columns is also available)

Dear members
During installation, the softwares create, change alot of files/folders, modifies registry etc.
Is there any sure way of capturing this process, in other words the log file.
Thanks for your time
Dear friends
I need these papers, please share:
Thanks in advance
