The paper describes a new constructive solution of prefabricated cross-beams manufactured be using off-shuttering molding technologies. Prefabricated elements of such cross-beams are pre-stressed trough-shaped parts. Together with hollow slab panels, stacked on the upper surfaces of their vertical walls, they serve as permanent shuttering for installing required crosswise and longitudinal (for support moments) reinforcement and for further pouring of cast concrete. The study provides a methodology and gives tests results of three series of prototype samples and of one full-sized prefabricated cross-beam. The purpose of the tests is to study the actual work of prefabricated cross-beams of the proposed construction. To analyze the test results, the authors performed check calculations of prototype samples according to the existing Russian design regulations of reinforced concrete structures. The obtained data analysis leads to a conclusion that the proposed construction of prefabricated cross-beams is quite reliable and makes it possible to give recommendations on their calculation and design.
