The moment of inertia of the girder in Figure P7.24 is twice that of the column. If the vertical deflection at D is not to exceed 1 in. and if the horizontal deflection at C is not to exceed 0.5 in., what is the minimum required value of the moment of inertia? E = 29,000 kips/in. 2 . The elastomeric pad at B is equivalent to a roller. Solve by the moment-area method. EI is constant.
