In the article there have been analyzed the results of experimental testing of strength of brick cellular-concrete piers (partitions), reinforced by the sheets from carbon-fibre fabric, against activity of static shearing load, simulating seismic load on masonry construction in case of earthquakes. Test technology has been provided. The experiment shows the options for reinforcing the brick piers (brick partitions) by the sheets from carbon-fibre fabric with one or two-sided position of reinforcement elements. There is a comparison with the results of tests of deviation (misalignment) of the unreinforced brick piers (brick partitions). There is a description of technology of fastening of the sheets to brickwork.

The paper analyses the issues of objectiveness of published data on advanced building materials and structures and current experimental methods used to determine design characteristics of building components erected both in ordinary and seismic areas of Russia.
When conducting experimental studies, it is important to observe continuity. Furthermore, the attention is to be paid to obligation to observe the required regulations in studies of new structures.
On Assessment of Earthquake Resistance of Sandwich Panel Connections with Steel Frame Using «HARPOON» Self-Drilling Bolt Screws
Issue:

The results of experimental studies in earthquake resistance of «HARPOON» self-drilling bolt screws (GLOBAL RIVET Company) under dynamic load are set forth. In the course of the tests using a two-component vibroplatform the dynamic effects were modeled in the form of the cyclic (harmonic) load, impulse input (seismic impact) and repeated transient load. Basing on the test results, the recommendations are given on using «HARPOON” fastening elements to connect cladding sandwich panels to steel frames of buildings to be erected in areas with 7-9 point seismicity.
