Problem Use slope-deflection method to analyze the frame shown below. Segments AB and BD of the frame have moment of inertia I. Segment BC has moment of inertia 2I. Modulus of elasticity E is constant throughout the frame. The frame is supported by fixed-supports at A and D, and by a roller-support at C. Joint B is rigid. A downward point load of 20 kN is applied at mid-span of AB. Uniformly distributed load of intensity 2 kN/m acting downwards is applied along BC. Consider flexural response only. 6 a) Calculate the rotation at B. b) Calculate the support moments at A and D. c) Sketch the deflected shape. EI) Hint: MN 2 20 kN 2 kN/m 21 8 m 4 m 4 m 4 m
