Why did you choose prestressed roof slab?Īs mentioned before, this solution covers all aspects important for design. This option fulfills all demands and moreover, we own a patent for this technology.

This solution was abandoned due to huge deflections which could have damaged the origin ceiling. The first option was a composite roof slab consisting of steel beam, trapezoidal sheet, and concrete slab. Stress limitation in the construction stage of end of design working life Application of IDEA StatiCa and MIDAS Civil What types of roof slabs have been considered in this project?
