PROJECT CIVIL RCC STRUCTURE Prestressed reinforced concrete ceiling

Prestressed reinforced concrete ceiling
of a sports complex "Victoria"

object model

  It carried out a verification calculation and expertise span from prestressed concrete.

  Plate made of heavy concrete class B30. It has internal reinforcement. Armature A500 grade (without pre-deformation). Geometric plate dimensions: length 39 000 mm, width 27 000 mm, height 1500 mm. Total estimated model plate is presented below.

Load, impact and combinations thereof

     load values ​​were set in accordance with the requirements

     1. SP 20.13330.2011 Loads and effects.

     Uploading models performed several load types: constant (own weight of the structure) and time (the load of the weight of the equipment, the people, the stored materials and products, and snow load).

After all the stress on individual loadings were created linear combinations of loads to which each of the loadings entered with the corresponding coefficients.
