“…Many researchers have studied two-way reinforced concrete slab systems for model improvement. The important things to study were the serviceability of the slab section which represent by the measurement of deflection and crack width [9]- [11]. Manish et al found that short-term deflections determined based on the provision for two-way RC slabs are not comparable with experimental values [10].…”

Adan et al examine the effects of cracking on two-way slab deflection and serviceability [11]. An attempt has been made by Hossain to produce simplified design charts to estimate immediate deflection for different end conditions and aspect ratios.…”

The self-weight of the concrete slab in high-rise building construction significantly affects the risk of structural failure in earthquake-prone areas as the earthquake force is directly proportional to the mass of the building. To reduce the building mass then the sandwich concrete slab is introduced. This study focuses on variations of aspect ratio effect on the slab behavior under central point loading. The aspect ratios are set at 1.0, 1.26, 1.5, and 2.0. A normal concrete slab with an aspect ratio of 1 as the control specimen is prepared. Tension reinforcement of D10-150 is placed in both x-and y-direction. While the compression reinforcement of P8-200 for both directions is used. The slabs were supported on four edges and tested under a central point load. Results found that the slab with an aspect ratio of 2.0 has a greater stiffness than other slabs as well as the resistance load capacity. The slab with an aspect ratio less than 2.0 behaves similarly with no significant differences. Generally, the slab ductility index decreases with increasing the aspect ratio. All slabs have ductile behavior which is indicated by both the strain measurement and the relationship of the load-deflection curves. An aspect ratio of 2.0 as the limit used by the Standard for distinguishing one-way and two-way slab elements is proven valid and acceptable.
