Structural Optimization is a method used in engineering and design to improve the performance of structures while minimizing material use and costs. It involves analyzing various design parameters to find the most efficient configuration that meets specific requirements, such as strength, stability, and weight. This process often employs mathematical algorithms and computer simulations to evaluate different design options. By adjusting factors like shape, size, and material distribution, engineers can create structures that are not only more effective but also environmentally friendly, reducing waste and resource consumption in projects like buildings, bridges, and other infrastructures.
