Challenge Problems

Consider a 4-story building modeled as an MDOF system. If the first mode shape is {1, -0.5, 0.3, 0.2}, what does this imply about the relative motion of the floors during the first mode?
💡 Hint: Consider the ratios of movement indicated in the mode shape.
A given MDOF system experiences a torsion when eccentric loading is applied. If the center of mass shifts to the right, how would you model this interaction?
💡 Hint: Think about how the loading impacts the movement of mass and stiffness in the model.
