Factored Load

Definition

Factored Load is the load imposed on a structural member multiplied by appropriate factors, used in the design of reinforced concrete members.

Purpose

The purpose of Factored Load is to account for various uncertainties in load predictions and material strengths by applying safety factors. This ensures that structures can withstand actual loads, including potential overloads and variations.

Examples of Use

• Building Design: Applying factored loads to ensure beams and columns can support the anticipated weight of floors, walls, and occupants.
• Bridge Construction: Designing bridge components to handle traffic loads, including potential overloads from heavy vehicles.
• Foundation Engineering: Calculating factored loads to ensure foundations can support the weight of the structure and resist settlement.

Related Terms

• Load Factor: A coefficient used to increase the nominal loads to account for uncertainties and variations.
• Design Load: The load that structural components are designed to support, including factored loads.
• Service Load: The actual load expected under normal use conditions without safety factors applied.

Notes

• Factored loads are essential in structural design codes and standards to ensure safety and performance.
• Different types of loads (e.g., dead loads, live loads, wind loads) may have different factors applied.
