The article presents the calculation of stress-strain state of the cable space frame that consists of space modular elements and flexible rods of the lower belt, which are connected with bolts. The cable space frame is double-layer roof system, consisting of spatial modules, connected to each other via bolted joints. The shaping of the structure is made through the flexible elements of the bottom chord, which are manufactured as cables. Taking into account the fact that the cable space frame is a completely new type of structure with the original design, the investigation of the stress-strain state of individual elements of the structure is a pressing issue. Therefore, the purpose of the work is to determine the specifics of the behavior and study the stress-strain state of cable space frame. The construction of an arched type a constructive scheme of which consists of flat hard drives and cable elements is considered. The mathematical model of calculation takes into account the geometric nonlinearity of such system.
