Hydraulics’ using to increase the load-bearing capacity of a beam
Annotation: The aim of this work is to increase the load-bearing capacity of beams, which will expand the range of building products. A hydraulic beam is a round pipe plugged at both ends, completely (without air cavities) filled with liquid. For reasons of geometric optimization, the best shape of the end plugs is a hemisphere. When a hydraulic beam is loaded, its lateral surface tends to deform. Consequently, the internal volume of the pipe tends to decrease. But, since the liquid is incompressible, it does not allow the volume to decrease, which, in turn, prevents the pipe from deforming. In a hydraulic beam, the entire load is relatively evenly distributed over the entire internal surface of the beam due to the liquid. (This is in accordance with Pascal's law - the pressure exerted on a liquid or gas is transmitted to any point without changes in all directions.) In a hydraulic beam, the entire load is distributed relatively evenly over the entire inner surface of the beam due to the liquid. The estimated load-bearing capacity of a hydraulic beam is five times greater than that of an I-beam and ten times greater than that of a tubular beam.
