Abstract
The weight of hollow slab system is not increased greatly with an incremental increase in its thickness. And the flexural stiffness of a hollow slab is not significantly lower than that of a general slab. There has been a growing need for hollow slab system, because long span structures are in great demand. But, the problem is occurred by vibration of floor slabs frequently in a long span structure. And the dynamic characteristics of a hollow slab system are quite different from the conventional floor system. It is required to investigate the safety and the serviceability of hollow slab. Therefore, there are a necessity for accurate vibration analysis. Hollow slab should be modeled by refined mesh for accurate vibration analysis. As the mesh of hollow slab is refined, the number of divided elements increases in numerical analysis. The number of node is increased and numerous computer memories or computational time are required. So it is very difficult to analyze refined model of hollow slab by using the commercial programs. For the efficiency of the Static Analysis, an equivalent plate slab model is used to represent static behavior of a one-way hollow slab system relatively precisely. In conclusion, equivalent plate models present the static characteristics of one-way hollows relatively precisely.
