Solve the frame shown using both portal and cantilever methods. Assume baseplate connections as fixed support. All bays are 15 -ft wide. First floor is 16 -ft high and the top two are each 12 -ft high. a) Assume columns and beams have A=50in2, and I=500in4, b) Repeat part (a) assuming beams moment of inertia is increased to Ibeams=2,100in4. Columns remain as Part (a). c) Repeat part (a) assuming beams moment of inertia is decreased to Ibeam=60in4. Columns remain as Part (a). Discuss results in terms of shear, and moments in various members and overall frame deflection. By deflection discussion it is meant how it relate to the moment diagram.
