摘要： A chord truss roof includes a ring-girder, cross beams arranged radially around the ring-girder, chord members stretched between the respective cross beams and the ring-girder. The roof supports itself by tensioning the chord members. The ring-girder has an upper compression ring, a lower tension ring, and plural struts connecting the two rings. The chord members arranged opposite one another with both end portions of the tension ring interposed therebetween are connected to the corresponding end portions of the tension ring, and are joined to one another via connection members which are disposed between both end portions of the tension ring. Further, each strut is provided along a line which bisects the angle made by a corresponding chord member and the plane defined by the tension ring.

摘要： With the conventional radiating truss roof support array, the inner-truss connecting members form multiple complete rings radiating from the central portion of the roof to the periphery at fixed intervals. When tension is applied to the periphery of the roof, a constricting annular compression is generated in each of the concentric rings of inner-truss connecting members. By this mechanism, the tension applied to the periphery is somewhat dissipated, and a less than optimal effect on the curvature of the dome of the roof is achieved for a given amount of tension applied to the periphery. The present invention concerns a radiating truss roof support array constructed in such a manner as to eliminate the above described problem of induced annular constriction in the concentric rings of inner-truss connecting members. This goal is achieved by interrupting the concentric rings of inner-truss connecting members at fixed intervals so that predetermined adjacent trusses are not connected together by the above mentioned inner-truss connecting members. the concentric rings of inner-truss connecting members thus formed are incomplete at predetermined portions and the annular constriction is thus eliminated. Thereby, the tension applied to the periphery of the structure is used to maximum effect in maintaining the curvature of the dome of the roof.
