ABSTRACT:
In a domed support structure, especially for roof construction, a compression dome is arched in lengthwise direction in a catenary configuration. A tension dome is further arranged either side by side or below the compression dome and is also arched in lengthwise direction in a catenary configuration. The compression and the tension domes are provided with a compression sheating and a tension sheating, respectively. The compression sheating is formed to have a high buckling strength. To this end the compression sheating is arched also in a direction transverse to said lengthwise direction. The arched shape is defined and maintained by corresponding transverse beams which function as stiffening or shaping elements but do not support any load caused by the own weight of the sheating. Such forces are transmitted by the sheating itself directly onto the bearings of the structure at its lengthwise ends. Thereby, the weight forces are equally distributed over the entire structure instead of being concentrated in a few beams or girders. The elements of the structure therefore can have relatively small cross sections and weights. Especially, wooden elements can be used for building the domed support structure of the invention.
