given 2D frame using classical methods.
a. Compute reactions for the given (2D) frame (verification also
should be done).
b. Compute axial forces N, shear forces Q, bending moments M and
draw their diagrams
c. Calculate dimensions of rectangular cross-section (W = ?) if
allowable stresses is 160 MPa;
d. In SolidWorks Simulation create the FE model of Beam elements.
Use structural steel S235 material. Compare the internal forces
diagrams. Using the rectangular cross-section with analytically
calculated dimensions, determine the Safety factor of the
structure.
The answer I got is this:
