EXPERIMENTAL STUDIES OF PROFILED FLOORING ARCHED UNDER CONSTRUCTION LOADS IN THE SLABS WITH LOWER VAULTED SURFACE SUBWAYS

Abstract

Experimental studies of permanent shuttering of profiled flooring, arched shape on the effect of mounting loads in the construction of precast-monolithic slabs slightly deepened underground pedestrian crossings. Considered the test scheme, valid work profiled flooring, arched shape. The dependences of the deflection from the action of mounting loads. Proven overall stability of the arches of the profiled decking. Recommendations for the use of profiled flooring arched as permanent formwork.
