Abstract

The article describes the main provisions of calculation and design of reinforced concrete hollow core prestressed formless bench molding  floor slabs, reinforced with cable armature classes K1400, K1500. Plates are designed without transverse and all any kinds of constructive armature. Slabs calculated as the structure, that having no cracks in the operational conditions. To minimize the cost, minimum concrete strength was define for the manufacture of the floor slabs. By varying the size of the temporary load, slabs span and bearing length on the wall number of floors of the building was defined,  that does not require amplification of the end portionsof the floor slab. Loss of prestressing are designed for slabs with the calculated cross section of reinforcement defined based on the strength analysis. The loss of temperature difference taken at delta T = 65 ° C, and the loss of retracting rope when cutting the monolith defined by the results of experimental studies (drawing on the length of 7 m averages 3.5 mm). The calculations presented a full nomenclature of slabs with a working cable armatures in various versions of reinforcing ropes with a diameter of 9 mm, 12 mm, 15 mm.

Keywords:  disk overlap, flexural stiffness, loading scheme.
