EX. US-20 Generating a Structure in Cylindrical Coordinates
This example generates the geometry of a cylindrical tank structure using the cylindrical coordinate system. The tank lies on its side in this example.
This problem is installed with the program by default to C:\Users\Public\Public Documents\STAAD.Pro 2024\Samples \Sample Models\US\US-20 Generating a Structure in Cylindrical Coordinates.STD when you install the program.
UNIT KIP FEET
1 10 0 0 8 10 315 0
Joint 1 has an 'r' of 10 feet, theta of 0 degrees and Z of 0 ft. Joint 8 has an 'r' of 10 feet, theta of 315 degrees and Z of 0 ft. The 315 degrees angle is measured counter-clockwise from the +ve direction of the X-axis. Joints 2 to 7 are generated by equal increments of the coordinate values between joints 1 and 8.
REPEAT 2 0 0 8.5
The REPEAT command is used to generate joints 9 through 24 by repeating twice, the pattern of joints 1 to 8 at Z-increments of 8.5 ft for each REPEAT
