What kind of load does the structural frame of a building need to withstand?

1. Only dynamic loads from winds and earthquakes

2. Dead loads of the building

3. Only live loads from occupants

4. Combination of live and dynamic loads only

The correct answer is: Dead loads of the building

The structural frame of a building must withstand dead loads, which consist of the weight of the building materials themselves, including walls, floors, roofs, and fixed equipment. These loads are constant and are present at all times, serving as a fundamental design consideration for the structural integrity of the building. In addition to dead loads, a well-designed structural frame also accounts for live loads, which are variable and can include occupants, furniture, vehicles, and other movable objects. Furthermore, the frame must also endure dynamic loads, such as those caused by wind or seismic activity, which can create fluctuating forces and moments. While the other options mention specific types of loads, they do not encompass the complete range of loads that the structural frame must accommodate. Dead loads serve as a foundational aspect of structural design, making the understanding and analysis of these loads crucial for ensuring the safety and performance of a building.
