Question
need input data files (codes) Please determine the shear (V), moment (M), and normal force (N) at A, B, C, and D for the portal-frame provided in Fig 1. The frame will be constructed of steel and the support/joint types and material schedule are provided in Table 1 and Table 2, respectively. Please analyze the structure using the preliminary and alternate steel sections, and note the differences in moment and deflection at A, B, C, and D. 4 k/ft Table 1. Supports and joints. C Joint Node Type Fixed Moment (fixed) Moment (fixed) Fixed 6ft 15 ft 15 k Table 2. Materials schedule Member Material Preliminary Alternate Section Section AB Steel W10x30 W12x40 Steel W10x30 W12x40 CD SteelW10x30 W12x40 6 ft BC Fig 1. Preliminary design from architectural plans. Please provide support reactions, joint displacements, member forces, and shear and moment diagrams, forExplanation / Answer
