For the given frame, assuming the horizontal girder may be infinitely rigid

For the given frame, assuming the horizontal girder may be infinitely rigid and the mass of the columns are negligible. Find the following: 1. Compute the natural frequency of the steel frame. 2. Compute the max. horizontal displacement at the given level for the following load functions, assuming no damping. (i) A force of 4k applied suddenly at t=0 and removed suddenly at t=0.3s. (ii) a force of 4 kip applied suddenly at t=0 and decreasing linearly to zero at t=0.5s. 3. Also determine the max. shear, moment and bending stress in each column for the rectangular impulse. Compare the max. static bending stress to dynamic bending stress.
