What type of structure relies on a frame for its support?

A framed structure relies on a framework of vertical and horizontal members to support its loads, making it stable and capable of spanning large areas. This type of construction typically uses materials such as wood or steel to create a skeleton that provides strength and rigidity. The frame distributes the weight of the building evenly and allows for flexibility in design, facilitating the erection of walls and roofs without needing solid, continuous supports. By utilizing beams and columns, framed structures can effectively handle various loads, including those from occupants, furniture, and environmental factors like wind and snow.

Other structures, such as frameless, reinforced, and composite, operate on different principles. Frameless structures do not utilize a rigid frame for support; instead, they might rely solely on load-bearing walls or other methods. Reinforced structures incorporate structural reinforcements, usually in the form of materials like steel reinforced concrete, which enhances their strength but does not inherently describe a frame being an integral part of the support system. Composite structures combine different materials to take advantage of the strengths of each, rather than depending solely on a framing system. Thus, the definition provided aligns closely with the characteristics of a framed structure, making it the correct choice.
