EXAMPLE 1-005 FRAME - DISPLACEMENT LOADING EXAMPLE DESCRIPTION Using a portal frame, this example verifies SAP2000 for settlement and rotation of normal supports, skewed supports (settlement only) and spring supports. Note that for spring supports, the grounded end of the spring is displaced or rotated. Six different models are created. The models are identical, except for the loading and the support condition at joint 4 as shown in the figure below. The results for various support reactions in each model are compared with independent hand calculations. Important Note: Only bending deformations are considered in the analysis. Shear and axial deformations are ignored. In SAP2000 this is achieved by setting the property modification factor for area to 100,000 and setting the property modification factor for shear area to 0.
