DETERMINATION DISPLACEMENT OF NODES OF THE STEEL AND CONCRETE COMPOSITE CABLE SPACE FRAMES BY EXPERIMENTATION
Journal Title: Збірник наукових праць Українського державного університету залізничного транспорту - Year 2017, Vol 169, Issue 3
Abstract
The article presents methodology specifics of experimental studies of the effectiveness of constructive solutions for new space systems. Research methodology developed by the example of full-scale prototype of the steel and concrete composite cable space frame in span 5.3 m, which includes the space steel and concrete composite modules and a flexible bottom chord. The methodology provides to study movement of the prototype by testing in the uniform load applied in nodes. It also provides the definition of displacement of nodes of the prototype. According to the developed technique, stressed state of the full-scale prototype of the steel and concrete composite cable space frame was studied with a mechanic method. Schemes of arrangement of equipment and devices for measuring displacements of the full-scale prototype of the steel and concrete composite cable space frames are presented. Drawings of full-scale prototype of the steel and concrete composite cable space frame are presented. The specifics of research method and measurement tools are described.
