The subject of this paper is the stability and strength of cold-formed and perforated steel sigma-section columns with steel sheathing of different thickness. Ceilings with and without steel sheathing of different thickness are tested to failure in compression on a laboratory machine, which was based on a manual hydraulic jack. Series of 4 experiments with full-scale walls (2.5 m height) were carried out. Also, for examination of the role of boundary conditions, the sheet in a ceiling is either left free or connected to base with screws.In civil engineering there are many experiments and methodologies for calculating the strength and buckling of ceiling with the sheathing of various materials, such as oriented strand board and gypsum board. However, for producing superstructures of ships the materials with high plastic properties and strength characteristics are required. For example steel possesses such properties. It was the main reason for conducting a series of experiments and studying the behavior of cold-formed steel columns with steel sheathing. During the experiments the deformation of the cross-section of three equally spaced cross sections was determined, as well as the axial deformation of the central column in the ceiling with steel sheathing.The test results showed the influence of the thickness of sheathing and boundary condition of a sheet on the strength and buckling of ceiling. According to the results of the tests it is necessary to evaluate the impact of the sheathing made of different materials and if necessary to carry out further tests.

PROSPECTS OF POTENTIAL APPLICATION OF NON-METALLIC FRP REINFORCEMENT IN FRP-REINFORCED CONCRETE COMPRESSIVE MEMBERS AS MAIN LONGITUDINAL NON-PRESTRESSED REINFORCEMENT

In the foreign countries there exist not only design guidelines but also standards for testing of FRP materials. These codes do not recommend using FRP bars in compressive members, such as columns. But the compressive strength shouldn’t be neglected according to those design codes. In our country the standards for FRP testing and design codes are just in the process of development. This paper contains the analysis results of the possibility of GFRP bars use as the main longitudinal reinforcement in compressive members. The most recent research data on this subject is presented. The studies show that the strength of the specimens grow rapidly with the decreasing tie spacing in columns. We can also make a conclusion that the GFRP bars contribution is only 5 % lower than the contribution of traditional steel bars. Some other research data shows that in case of the tie spacing close to the design codes limitations there is no strength increase in the same specimens made of plain concrete.

The following conclusions were made upon completion of the testing of crane beams:
The lowest rigidity is demonstrated by welded beams exposed to temporary mobile loads; the maximal buckling caused by temporary mobile loads is equal to 12 mm, or 1/1,1790 of the span; the rigidity of crane beams of an overflow dam meets the requirements set by Section E2.1 of Construction Rules 20.13330.2011 "Loads and Actions".
In general, the authors state that the crane beams of the span structure of the overflow dam are in a serviceable operating condition, according to their opinion issued upon completion of examination and testing procedures. The recommendation is to regularly tighten screw nuts and to install high-strength bolts in the points of missing rivets. The authors also recommend applying a rust-proofing coating to all metal structures of the dam spans.
