Waffle hollow-core composited floor, composed of cast-in-place beams and prefabricated concrete box fillers, has the advantages of large span, lightness, convenience in construction, various adaptation and lower cost,suitable to the large column span and bay width floor structure. 双向密肋装配整体...
Supported between spans by load bearing wall with any inclination with respect to that of the roof. Waffle slab. Removable form. FIR517 Support at span end by concrete wall parallel to the slope of the roof. Waffle slab. Lost form.
The effects of shear span, depth of the rib in the waffle slab, thickness of the slab (hf1), and width of the flange were investigated. Theoretical models were also developed to predict the ultimate bending and shear resistance of the SUCBWS. The following conclusions can be drawn from ...
column-slab connection.The objective of this research is to investigate the seismic performance of waffle-flat-plate floor systems engineered to resist low earthquake excitations in low to moderate seismicity regions. The models investigated represent structures built between the seventies and nineties in...
