Strengthening of structures overlap from busting

Devoted to the problem of ensuring the strength punching beamless, non small caps slabs. This problem arose in connection the increasing use of such overlap in the practice of construction, as well as the release of new design standards that require to take into account in the calculation of floor slabs on the punching action is not only the lateral force, and bending moments. The latter circumstance has led to a significant increase of the vertical reinforcement plates on bearing plots the columns. The article discusses the possibility of replacing the vertical reinforcement in the zone set in the punching pyramid anchor.
