| Abstract: | According to the experimental results of four single hollow slabs and four jointed hollow slabs.This paper analyzes the failure mode,failure mechanism and shear properties of the slab and gives the main effective factors of its shear stength.Furthermore,this paper puts foreard the formula for the calculation of shear stength of slabs.The calculated results are in good agreement with the rneasured ones.The suggested formulas were found to be very economic,safe and reliable and of great practical application. |
