LOAD-CARRYING CAPACITY OF PRESTRESSED HOLLOW CORE SLABS . NORDIC CONCRETE RESEARCH. PUBLICATION NO 7
A design method based on the true failure mechanisms of the prestressed hollow core slabs is introduced. 340 full scale load tests have been analysed and the calculated results have been compared to the experimental ones. It is concluded that the design against the shear compression failure mode can be replaced by the design against the Anchorage failure mode. The modulus of rupture of concrete seems to be insensitive to the thickness of the slab. It is also smaller for the hollow core slabs than for the rectangular beams made of plain concrete. Furthermore, the shear capacity of the thick slabs may be overestimated if the tensile strength of concrete is supposed to be the same in the web as on the top of the slab. (Author/TRRL)
