Klijuotųjų medienių sijų jungties su įklijuotaisiai plieniniais strypais tyrimas ; Investigation of connection of glulam beams with insetted steel bars
In this master degree paper are discussed advantages and imperfections, practice and use in construction industry of glulam with glued-in steel rods. Theoretical calculations analysis according to Eurocode and Russian standards of glued-in steel rods parallel, perpendicular and at an angle to the grain were made. Theoretical calculations of rigid joint glulam beam with glued-in steel bars were made. Tests methods were analyzed. In the part of the researches these tests were made: yield stress evaluation test of steel rods; moisture and density evaluation tests of wood; parallel, perpendicular ant at an 45 o angle to the grain compression tests of the glued-in steel rods; rigid joint of the glulam beam with glued-in steel rods test. Fundamental factors, which have influence to the results of the tests, character of the disruptions and the behavior of elements during the experiments were defined. The results of the calculations were compared with the results of tests in which natural size specimens were tried. In this work the results of theoretical calculations and experimental tests are proposed, evaluated and analyzed. The reasons of divergence in results are indicated. Recommendations and suggestions how to improve the methods of calculations and for better use the glued-in steel rods in the practice were offered.
