Structural Frame Analysis: Determining Shear and Bending Diagrams

[mohamadh95]

Homework Statement

Hello. I've created a small program to find shear and bending diagrams of the members of a frame. I was able to get the reactions at the support but don't know how to continue from now. This is an example of a frame all columns are 3m in height and the beams 8m. All the beams have a distributed load of 50 KN/m. I used the direct stiffness method and programed it using mathematica and the values are correct(checked with some examples from some books). Thank you in advance.

AB=8000KNAC=3200KNAD=3200KNHomework Equations For a beam under shear and bending, the following equations can be used to calculate the shear and bending forces:Shear Force = (V/L)*L Bending Moment = (M/L)*L The Attempt at a SolutionTo determine the shear and bending diagrams of the members of the frame, you will need to use the equations stated above. You will need to calculate the shear force and bending moment at each point along the length of the beam. The shear force can be calculated using the equation V/L*L, where V is the reaction at the support, and L is the length of the beam. The bending moment can be calculated using the equation M/L*L, where M is the moment at the support, and L is the length of the beam. Once you have calculated the shear force and bending moment at each point along the length of the beam, you can plot them to find the shear and bending diagrams of the members of the frame.
