The behavior of lightweight precast slab autoclaved aerated concrete bamboo reinforcement

The construction of high-rise buildings requires innovation in its implementation system. The precast system is more popular because it is more efficient in terms of time. Ribbed slabs, or two-way plates, are slabs supported by beams on all four sides and supports carrying the load in both directions. Theoretical studies with the software on ribbed or grid plate systems have been carried out. However, there are still not many experiments that support and test the study. This study will test an innovation by filling the rib box with AAC. This experimental approach aims to obtain a lightweight precast plate model. In this article, we will analyze 3 test objects with three treatments on the primary reinforcement and its tensile on the corner supports. The results showed that the most excellent stiffness value on the A1B1 plate was 414.226 kg/mm, while the ductility values obtained were relatively the same as the two specimens, A2B1, and A1B2. In addition, it was found that adding bam-boo as tensile reinforcement did not increase the maximum carrying capacity of the plate. Meanwhile, lightweight brick placed on the rib box reduces the concrete density to 1700 kg/m3. The crack pattern that occurs is a shear crack, which then becomes a flexural crack.
