Research of the influence of the dimension of joints preliminary reduction in the spatial rod coating on the work of the adjacent joints

Abstract

The article deals with the design of an experimental fragment of spatial rod coating of the pre-stressed continuously reinforced frame elements and the external load testing approach. There some results of the research of the work of the racks and pre-cogged bolt nodes of the lower part of frames under load. Also it is what the impact of the force of joints reduction on the work of adjacent frames racks. Due to the experimental data the joints reduction force calculating approach is given.
