“…The slab with an aspect ratio of 2.0, however, has stiffness higher than the other sandwich slab. This is much similar to the behavior of the RC beam which presents a one-way element [5,6]. Therefore, using 2.0 as the upper limit for the definition of one-way and two-way slab elements is acceptable.…”

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.

“…The flexural elements of one-way sandwich concrete structures represented by beams have been studied by the authors under static loading and even testing for their fireresistant [5,6]. However, the sandwich section using pumice concrete in the two-ways slab system still lacks study.…”

“…The reports show that the used of this material can be satisfactorily applied for medium structural element. Precast element for frame system has also been introduced with and without infill wall [1,2]. The other advantage of using lightweight concrete is to resist high temperature and fire resistance [3].…”

The potential of natural resources such as pumice and sisal fiber for simple housing structural components is investigated in this research. Behavior of sisal fiber reinforcement of lightweight concrete beam under flexural loading was examined. The purpose of this study is to identify the prospect of sisal fiber as a replacement of steel bar reinforcement for structural element. The variations of reinforcement ratios were considered in order to optimize the performance of sisal fiber reinforcement. Twelve beam specimens size 100 x 150 mm with clean span of 1.5 m were examined in this investigation. Four variations of beam reinforcement were explored consist of 3 sisal fiber variation and 1 steel reinforcement as a control; where every variation was presented with three samples. Enerpac hydraulics Jack with 50 ton capacity connected to the load cell was operated as a source of loading. LVDT was fitted in the mid-span to measure vertical deflections during the loading. Test results indicated that the crack moment experiments were higher than the crack moment calculations. The valued were 1.44, 1.52, and 2.72 higher for sisal fiber reinforcement of B-LF, B-MF and B-HF, respectively. Whilst for steel reinforcement of B-LS the valued were 3.32 higher. Observation results also indicated that the moment resistant capacities of the specimens were twice higher compare to the calculated moment capacity. However, The lowest sisal reinforcement (B-LF) has only about 10% different service moment compare to the steel reinforcement (B-LS) where they both have equal ρ = 1.206 %. This indicate that the use of sisal fiber have considered as insignificant different service moment capacity to the steel reinforcement.
