U8 Load Calculations Questions and Answers | Latest Version | 2024/2025 | Correct & Verified What is the primary purpose of load calculations in construction? To ensure structures can safely support the loads they are subjected to. Why is it important to consider live loads in calculations? Because live loads account for temporary or moving forces like people and equipment. What does dead load refer to in load calculations? The weight of permanent fixtures and structural components. Why is the safety factor used in load calculations? To provide a margin of safety by accounting for uncertainties in the design and materials. How is the total load on a beam determined? By adding the dead load and live load applied to the beam. 2 What is the unit commonly used for measuring loads in structural calculations? Pounds per square foot (psf) or kilonewtons per square meter (kN/m2). Why is wind load considered in building design? To ensure the structure can resist forces caused by wind pressure and suction. What is the effect of concentrated loads on a beam? They create specific points of high stress that must be accounted for in the design. What is meant by distributed load in structural engineering? A load spread evenly across a length or area. Why is it necessary to account for dynamic loads? Because they involve forces that change rapidly, such as impacts or machinery vibrations. What is the role of load-bearing walls in construction? To support the weight of the structure above them. 3 Why are snow loads important in roof design? To ensure the roof can safely support the weight of accumulated snow. What factors influence live load calculations for a building? The intended use of the building, such as residential, commercial, or industrial purposes. What happens if a structure is not designed for seismic loads in an earthquake-prone area? The structure may fail due to the forces caused by ground motion. Why are point loads critical in foundation design? They concentrate forces on specific areas, affecting soil bearing capacity. What is the difference between uniform and variable loads? Uniform loads are evenly distributed, while variable loads change in intensity over an area or length. Why is load path analysis important in structural engineering? To ensure that all loads are safely transmitted to the foundation.
