Response of Post-Tensioned Two Way Flat Slabs to Vibration.

As PT floor slabs become thinner, a doubt about its vibration behavior and comfort of occupants arises. This paper investigates several approaches for determining the post-tensioned human induced vibrations which can give high accuracy be considered as simple tools guide designers. It also studies with different span length, thicknesses relates response to natural frequency floor. The results show that slab is increased by decreasing length or increasing thickness. peak acceleration mainly decreased achieving acceptable thickness ratio all lengths studied. indicate practical thickness-span ratios designed deflection are expected vibration. limits validity floors discussed.
