Abstract: A comparative experimental study on the elastic deformation of a new type of post-constructed hollow-ribbed floor was conducted. The elastic flexural stiffness contribution of post-constructed precast slabs on the new type of floor was studied. Look-up table method and finite element method were used to calculate the mid-span deformation of the rib beam of the floor and calculation results were compared with the experimental results to verify the rationality of considering the elastic flexural stiffness contribution of precast slabs on the new type of floor. The corresponding recommendations were given, which can provide reference for the design and application of the new type floor system.
Keywords: post-constructed; hollow-ribbed floor; elastic stiffness; experimental study; finite element analysis
