Study on the Deformation Mechanism of Floor Slab with Hole under Horizontal Earthquake

Abstract:

Using three slab models (elastic plate, elastic membrane and rigid plate), the column displacement of one storey frames with different slab-hole ratio, column size and slab thickness under horizontal earthquake were calculated to investigate the driving and limiting factor on the in-plane deformation of floor slab. An influence factor concerning structure stiffness, floor slab stiffness and representative value of gravity load was proposed on the concept of fixed zone and deformed zone. A linear relationship between in-plane deformation and the influence factor was obtained based on the statistic data of 18 examples. Results show that the effect of out-of-plane stiffness of floor slab is very small and negligible and the in-plane deformation of floor slab can be kept within a reasonable range by balancing the structure stiffness of slab strips around the hole and deducing the length-width ratio of floor slab located at deformed zone.
