Hello everyone, im trying to draw a frame-line that has start-joint named 'JointI' and end-joint named 'JoinJ'. It is illustrated below:
For now, I already create top and bottom frame-line, but i am facing difficulity when creating diagonal frame. I have data frame-line TOP and BOTTOM which each frame contain its start-joint & end-joint. Do u know how to create thoose diagonal frame automaticly using 'for-loop' method.
Here i give my code:
clear;
clc;
H = 5;
L = 15;
Ns = 2;
Nb = 1;
PortalHeight = H;
Bayspan = L;
NumberStory = Ns;
NumberBay = Nb;
% Variable1
h = [0.8,1.00,1.20,1.40,1.6,1.80];
% Variable2
Lss = [2.00,2.40,2.80,3.20,3.60,4.00];
% Variable3
Nss = [2,3,4];
% Definition
Var1HeightofTrussBeam = h;
Var2LengthSpecialSegment = Lss;
Var3NumberSpecialSegment = Nss;

%% Name the Frame
% diagonal ordinary segment (DOS) %write down the code below give me one
% example in variant {1,1}
frameTOS = frameTOS{1,1}
frameBOS = frameBOS{1,1}
I want the result as a table and contain like this :
for variable column 'frame ID' you can use random number.
for variable 'JointI' and 'JointJ' must meet the requirement of my photo above.
im sorry that this is complicated..
