Load-bearing beams are essential structural components that support weight and ensure the stability of a building. They carry loads from the roof, walls, and floors, transferring them to the foundation. Understanding the principles of structural load-bearing is crucial for designing and constructing sound structures. Considerations include types of loads, material properties, performance characteristics, and adherence to building codes. From wood and steel to concrete and LVL, various materials offer unique load capacities and deflection resistance. By following best practices and leveraging the expertise of structural engineers, architects can create efficient load-bearing beam systems that meet safety and performance requirements.
