Structural analysis is a method used in engineering and architecture to assess the stability and strength of structures like buildings, bridges, and dams. It involves calculating the forces and stresses that a structure will experience under various conditions, ensuring that it can safely support loads without failing. This process typically includes the use of mathematical models and simulations to predict how structures behave. Engineers analyze materials, shapes, and connections to optimize design and ensure safety. By understanding how different elements interact, structural analysis helps prevent structural failures and enhances the durability of constructions.
