This program calculate data of beam, col and slab for ramp. It creates CSV file that can be used in sap2k or any FE package. It requires gnuoctave/matlab to work. You can download it from here:
- spiral.m = calculate and plot ramp in octave/matlab
- beams.m = calculate data of beam for ramp to be used in FE
- cols.m = calculate data of columns for ramp to be used in FE
- slabs.m = calculate data of triangular slab for ramp to be used in FE
Circle plot requires x = r*sin(t) and y = r*cos(t) where t increments from 0 to any given radians. If we increment z from 0 to given height h with some increment, and plot with x and y of a circle, we will get a 3D spiral curve. Two such spiral curve can be used to calculate data point for ramp. Below is the sample code. You can run this by copy and paste directly in gnu octave or matlab or create script out of it.
By using, beams, cols and slabs script function, csv data will be created that can be formatted as per any finite element code. Here I formatted it for sap2K.
A spreadsheet with sample sap2k format is attached with this code. Below is video tutorial explaining usage of this code:
