3.3 Building Forms Conceived as Solid Structure In order to show the relationship of 3D to 2D analysis, building forms can be conceived as solid structure: Composed by a series of slices,interact each other. Vertical loads:axially transferred from one subsystem slice to the next. Horizontal loads:transferred from one subsystem to the next by shear resistance between slices
