Raduga experiment: Multizonal photographing the Earth from the Soyuz-22 spacecraft

The main results of the scientific research and 'Raduga' experiment are reported. Technical parameters are presented for the MKF-6 camera and the MSP-4 projector. Characteristics of the obtained materials and certain results of their processing are reported

On the results of experimental and numerical studies of the stress-strain state of concrete structures reinforced with pre-stressed polymer composite links

© 2019 IOP Publishing Ltd. As part of the work, experimental and numerical studies were carried out to assess the stress-strain state of concrete structures reinforced with polymer composite reinforcement. The experiment and numerical simulation obtained good consistency of the results. The research results showed that the pre-tension of links made of polymer composite reduces the deformability of the beams, by reducing the deflections by more than 4 times. Concrete structures, reinforced with pre-stressed strands of polymer composite, can be used in building structures for industrial and civil purposes, transport construction
