tailieunhanh - Problem W - Simple Beam With Trapezoidal Loads

Determine midspan deflection of beam. Ignore the self weight of the beam. Create the model as follows: 1. From the File menu, choose New Model From Template. Select the Beam template in the upper left hand corner. Set the number of spans to one. 2. Define the frame section properties. 3. Apply the loads to the beam. 4. Use the Divide Frames option in the Edit Menu to break the beam into two elements with a joint at the center. | Problem W Simple Beam With Trapezoidal Loads Steel E 29000 ksi Poissons Ratio Beam W21X50 To Do Determine midspan deflection of beam.
