Step 1: Obtain Deflected Shape

Based on the lane Lane discretization, the program creates lane loading points along the width and length of each lane in the model. Then it places unit load in gravity direction at each lane loading point to determine the deflected shape. The unit load applied to the lane loading point is proportionally distributed to the tributary joints in the model. Using "Display > Show Lanes > Show Structural Connection For Selected Point" you can display the connections between the lane loading point and the joints in the model. So if our model contains 1000 lane loading points, the program would calculate 1000 deflected shapes, each corresponding to a unit load at each lane loading point. These deflected shapes are then used to determine all response quantities.
