How does the main structural system work in a brickwork official building?

In a brickwork official building, the main structural system typically consists of load-bearing walls made from bricks and mortar, which distribute loads vertically to the foundation. The walls provide both structural support and insulation, while the arrangement of bricks can enhance the building's aesthetic appeal. Additionally, arches and lintels may be used to span openings, allowing for Windows and doors without compromising the integrity of the walls. This system effectively combines durability with functionality, making it suitable for various official building applications.
