Type I Structure (Rigid Frame System)
Rigid frame systems consist of rectangles of vertical columns and horizontal beams connected together in the same plane. It should be noted that a bearing wall is a special case of the rigid frame system.
Type II Structure (Shear Walls)
The shear wall formation is a thin slender beam cantilevered vertically to resist lateral forces. It can take the form of a rectangle or box-shaped core, which can be used to gather vertical transportation and energy distribution systems (e. g., stairs, elevators, toilets, mechanical shafts).
