slab template is a pressed steel template which spans the support beams on the left and right sides; the end of the ribbed floor slab template is positioned on the top of the beam template; and a plug is arranged between the end of the ribbed floor slab template and the beam template. ...

This paper presents the analysis of slab-beam type floors using theboundary element method. The shear-deformable plate bending theory according to Reissner is used to model the slab, whereas the Bernnoli–Euller beam model (without losing the generality) is used to model beams. The developed for...
Footfall Response of a Concrete I-Beam Floor Structure (Ungar and White, 1979) Control of Floor Vibrations When it is desirable to control floor vibration for human comfort, it is important to limit the maximum amplitude as well as increase the damping. If the driving force is footfall, we ...

I will turn the LVL beam at a 45 degree angle to the corner where the radius projects. Should I use LVL’s as floor joists? It doesn’t appear that a 14″ TGI will support the span. Craig Reply Todd Can you be more specific about the layout…not sure I really understand what ...

where D is the flexural rigidity of the sample and the unit is N·mm2; l is the three-point bending span and the unit is mm; a is the length of the outrigger beam and the unit is mm; Δp is the load increment value on the load-deflection curve and the unit is N; and δ is...
During the test, the load cell was connected to the tension bracing by a longer arm fixed to an overhead beam, moving the load cell slightly sideways especially during the large deformations. To simulate the loading and this sideways movement, a maximum displacement of 14 mm in the axial ...
where a/g is the acceleration ratio, W is the weight of the beam, β is the modal damping ratio and R is a reduction factor, which involves the location of the person along the beam instead of at mid-span. Furthermore, it considers that there are two persons, the walker and the ann...
