The design live load for a shopping mall refers to the load that is imposed on the structure due to the presence of people, equipment, and other movable items. It is an essential factor in structural design to ensure the safety and stability of the building. Engineers typically refer to codes and standards, such as the International Building Code (IBC) or local regulations, to determine the appropriate live load values for different areas of the mall. These loads are then used to design the floor, roof, and structural systems to withstand the expected forces.
