[REQUEST] Preliminari design for space truss structure

[wahyoe]

hi
Can you help me, if you anyone has examples of "preliminary design" and the assignment? for space truss structure, for example:
a. electrical tower
b. antenna tower
c. space frame roof structure
d. and others associated with space truss structure
I want to know how the steps to calculate the structure or any reference to plans of space truss structure (examples of calculation), these calculations would I use to make the program analysis using matlab ..
thank you for your attention
greeting
Wahyoe
