Abstract: One-way steel reinforced pumice lightweight concrete slabs with bamboo permanent formwork to support building structure system are discussed. This paper aims to study the behavior and strength resistant of the slabs under flexural loading test. Eleven slab specimen divided into four groups namely BSN, BSL, BSM and BSH were considered. The slabs cross section was 550 x 120 mm with steel reinforcement ratio of 0% (BSN), 0.39% (BSL), 0.48% (BSM) and 0.77% (BSH). The slabs of 2.7 m length were supported at 2.5 m clear span. BSN was used as control specimen. The slabs were tested under two symmetrical point load acting on 1/3 clear span. The results showed that the first cracking load of BSH, BSM and BSL were generally higher than that of BSN. The present of steel reinforcement in the bamboo slab proportionally increased the slab capacities. Normalized ultimate load of BSL, BSM and BSH to BSN were 2.27, 2.64 and 4.04 respectively, where the average ultimate load capacity of BSN was 15.575 kN. Service load to ultimate load ratio of the slab with steel reinforcement were obtained varies between 0.37 and 0.57. Increasing the number of reinforcement ratio, it was found to decrease the slab ductility. The ductility index of BSL, BSM and BSH were 2.84, 2.09 and 1.34 respectively while BSN ductility index was 1.71. The effect of additional lateral reinforcement in the slab increased the slab ductility of 3.85, 2.15 and 1.56 for BSL, BSM and BSH respectively. [ABSTRACT FROM AUTHOR]
