Abstract

Purpose. The article is devoted to snow load emergency situations prevention using the laser rangefinder monitoring system equipment for steel horizontal structures.

Methods. Experimental and theoretical studies on the steel roof truss deflections under snow load using the monitoring system equipment.

Findings. It was found that the steel roof truss deflections under snow load, obtained with the laser rangefinder monitoring system equipment Sense S-One, correspond to the data of a more accurate measuring instrument – a TST (total station theodolite), and conform satisfactorily with the calculation results.

Conclusions. The values of the laser rangefinder monitoring system data correspond to the data of a more accurate measuring instrument – a TST (total station theodolite). It might be mentioned that the error of the laser rangefinder monitoring system does not allow to evaluate the results with a value (or step) less than 2.0 mm. The calculated deflection in comparison with the experimental data was constantly 44 % higher, which indicates a correlation between the calculation results and experiment. Higher calculated values of deflection are acceptable, because they are obtained for idealized hinge support conditions and give a safety margin.
