Abstract
The results of full-scale test of conveyor gallery’s span for stiffness control in building conditions and numerical work are given. In 2016-2017 at grain terminal’s building near ‘Yujniy’ port assemblage of metalware was in progress. One of the assembled constructions was under test gallery. After it assemblage geodetic survey was done, that shows geometrical declinations from design position. For given reasons goals of research were generated: 1. Gallery’s span (Ps-3) stiffness control (full-scale test by loading method); 2. Numerical calculation of gallery’s constructions; 3. Comparison of experimental and calculated data. Full-scale test of gallery’s span was realized by loading method. This method means that in characteristik points is mounted static weights. Weights were used to load the span (their weight was identical to the real load of equipment in exploitation period). Loading was sequentially in four nodes of span. Each block step had 15-minutes time lag. After last block step unloading was made. No time lags were made during unloading. At test time vertical displacement of bottom chord of span were measured. Measuring were made in central points of a span. The measuring equipment were clock-type deflection indicators with division value of 0.01 mm. Simultaneously geodetic control of characteristic points displacement was made. Numerical experiments were made in finite element complex ‘LIRA-SAPR 2015’. The order of calculations was the same as order of weight’s loading at full-scale test. Calculated displacements of bottom chord of gallery’s span (Ps-3) shows good convergence with experimental data (difference between 1.2% to 5.0%). Comparison for nodes in center of gallery’s span was given in article. In article shows recommendations for further using the construction of the conveyor gallery.
