Carrying out second order analysis with software
Carrying out second order analysis with software
(OP)
I have used an old DOS based software strsolv for structural analysis.
The program takes input for 3D frame, member inertias, loads, and various combinations of Dead, live and lateral loads. The program reports moments, shears, axial forces etc for all members, and can even give forces at various segments. The program is also able to calculate, x, y, z displacements and rotations at frame joints.
Since I do not know internal working of program, so I am not sure whether software performs first or second order analysis.
Assuming that the results are first order one will have to use moment magnification factors on reported results, otherwise for second order can perform direct design on reported values.
Is there some rough check or criteria to tell whether reported results are first or second order....
ad what sort of inputs are given to a software for second order analysis.

Not that the clock always reads "beer-thirty"....
