solve a truss structure using SAP program we will include 

1- Draw the truss and define the hinged connection 

2-Obtaining the supports and loads at the truss

3- the the material and section we will used

4- run the model and get the strainning action like shear and a moment and axial force

5- ger the deformation shape of the truss and values of the deformation 

6- the reactin force at the sopports
