construction of dome structure

The dome is like an inverted bowl. Precise mathematical calculations must be made before construction. The stress of the entire structure must be "perfectly balanced", otherwise the heavy dome will cause cracks in the circular wall supporting it underneath.

This was done by first forming a hemispherical support structure out of lighter wood and then laying bricks from the bottom. After the brick structure is stabilized, the wooden shelves can be removed; then the interior and exterior are decorated in sequence. The dome is a brick structure made of bricks that are gathered layer by layer toward the center. For concrete, the inner and outer formwork is supported, steel bars are tied in the middle of the formwork, and then concrete is built to form an arch shell structure.

The first two structures have disadvantages such as large load, low structural flexibility, poor seismic performance, high cost, and long construction period, so they are not ideal structures. Buildings with domes are unusual, and the architects commissioned to create domes are masters, but domed structures are complex and not always successful. The dome itself is self-sufficient, and to avoid lateral restrictions, a triangular ring structure is used to prevent the dome from expanding.

In order to ensure that each of the four support ribs is properly loaded, the dome is as axially symmetrical as possible along one direction. Dome construction began in Rome, and civilizations in different periods have adopted this semicircular structural form. Today it is also one of the architectural styles we are most familiar with. It continues to be used to decorate temples, churches, mosques, monuments, and even government buildings.

Extended information:

The dome is divided into brick structure, concrete structure, and now Steel structure.

Concrete structures have existed from modern times to the present. Then there are the steel structures in recent years. Steel structures are divided into grid structures, membrane structures, and hbk construction makes steel structures. The dome made of steel shell structure looks like a steel helmet.

When dome architecture first appeared, it had religious significance. Looking up from inside the building, the dome is as sacred as heaven, which makes people feel awe. Viewed from the outside, the high dome located in the center of the building dominates the surrounding buildings, making it solemn, elegant and majestic.
