With the construction of public buildings such as airports, exhibition halls, gymnasiums, commercial centers, etc., the space span of buildings is getting larger and larger, and the light entering the room through doors, windows, and curtain wall glass can no longer meet the needs of indoor lighting. It is a new development trend to set up a large area of ​​glass dome building for indoor lighting and minimize the energy consumption of indoor electric light sources, which can not only make the building more beautiful and elegant, but also reduce energy consumption.
The glass dome is an integral part of the building, and it also develops with the development of the building and its materials.
Glass is a brittle material with mechanical properties similar to concrete, with good compressive properties and poor tensile properties. The special feature is that the support system of the glass roof is to directly transfer the various loads borne by the surface glass to the main structure of the building. Therefore, it is the main force-bearing component, and the structure is generally selected according to the building shape and the size of the load it bears. form and material.
