This article is devoted to solving the problem of developing a high-precision radio direction finder for radio emission sources detecting. The paper substantiates the relevance of these devices to date and identifies areas of application. Two versions of the direction finder have been developed - with an operating bandwidth of 100 MHz and a wide-range version with an operating band of about 2000 MHz. Two layouts of these radio direction finders were made, and full-scale tests of individual units of devices and devices as a whole were carried out.

The article is focused on the methods of calculating bearing capacity of reinforced concrete strengthened in different ways. It examines calculation data on the bearing capacity of the reinforced concrete beams.

Thepromising field of efficient precast structures application is industrial flat plate framework (of “CUBE” system type). For today, this framework has undergone many improvements, and therefore it can be recommended for solving the tasks of the program for providing citizens with affordable housing. Columns, inflexibility elements and floor slabs are included into the framework composition. Internal forces in slabs are distributed unevenly, that is why it is reasonable to reinforce slabs according to the methodology of the materials curve construction.
