“…The behavior of BRC beams is generally far better than PCC beams. The shear and flexure behavior of BRC with 3.8% bamboo reinforcement becomes very similar to RCC beam with 1.23% steel reinforcement [21].…”

This paper presents the outcome of an experimental investigation of the behavior and strength of reinforced concrete beams with bamboo reinforcement. A total of five beam specimens were tested in flexural under four point (pure bending) loading. A plain concrete beam (B1) served as a control beam. Two specimens (B2 and B3) were longitudinally reinforced with four bamboo culms and steel stirrups. The last two specimens (B4 and B5) had similar longitudinal reinforcement but bamboo pieces were used as shear stirrups. The bamboo culms used in two specimens (B2 & B4) were treated with bitumen along with sprinkling of fine particles of sand to achieve rough surface for better bonding with concrete. The introduction of bamboo reinforcement increased the stiffness, strength, and ductility of beams significantly as compared to the plain concrete beam. The ultimate load carrying capacity of bamboo reinforced concrete beams was found to be 2.49 to 3.29 times that of control beam. The observed ultimate load was 25% and 13% more for specimens with coated reinforcement in case of steel stirrups and bamboo stirrups respectively. The specimen with coated bamboo reinforcementand steel stirrups achieved the highest ultimate load among all specimens.

“…Penggunaan bambu sebagai bahan bangunan konstruksi telah banyak digunakan oleh masyarakat pedesaan, seperti konstruksi rumah tinggal sederhana, rangka jembatan semi permanen, konstruksi rangka gudang, konstruksi turap pada saluran irigasi, dan sebagainya. Bahkan penggunaan bambu sebagai material alternatif pengganti tulangan baja dalam konstruksi beton telah banyak dilakukan oleh peneliti, diantaranya Ghavami (2005), Dewi & Nuralinah (2017), Mali & Datta (2020), Kathiravan et al (2020), Muhtar et al (2019), dan lain-lain. Alasan bambu digunakan sebagai material alternatif tulangan baja karena kuat tariknya yang cukup tinggi.…”

Tulangan bambu yang sudah dibentuk biasanya mempunyai permukaan licin hampir 50%. Namun, pada permukaan licin tulangan bambu adalah letak kekuatan serat yang paling tinggi. Tujuan penelitian ini adalah untuk meningkatkan kuat tarik tulangan bambu dengan memasang klem selang pada tulangan bambu. Metode yang digunakan adalah uji pull-out tulangan bambu dengan dimensi 15x15 mm 2 yang ditanam pada silinder beton berukuran diameter 150 mm dan tinggi 300 mm. Pengujian dilakukan dengan mesin UTM kapasitas 500 kN. Hasil pengujian menunjukkan bahwa kuat tarik cenderung linier positip seiring dengan meningkatnya jarak pemasangan klem selang. Tulangan bambu dengan treatmentt lapis perekat dan klem selang jarak 5 cm mempunyai kuat tarik tertinggi sampai 400,35% dari tulangan bambu normal. Penggunaan perekat pada tulangan bambu harus dilakukan sebagai lapis kedap air dan mengurangi permukaan licin.

“…Qaiser et al [11] developed different techniques to improve the adhesive property between concrete and bamboo rebar. Mali and Datta [12,13] used bamboo strips as the main reinforcement in concrete slab panels and beams and investigated their effectiveness and feasibility through testing. The structural behavior of the slabs with bamboo reinforcement was slightly higher than that of the RC slabs using mild steel bars.…”

A novel bamboo-concrete composite structure with threaded reinforcement connections is presented. Experimental investigations on the shear behavior of the connectors and the flexural performance of the bamboo-concrete composite beams were carried out. The results indicate that the load-slip behavior of the shear connection with threaded reinforcement exhibits good ductility and that its failure mode is ductile failure. The threaded reinforcement provides an efficient connection before the initial shear failure. The load-displacement curves of the bamboo-concrete composite beams are close to those of the full composite structure, and the midspan displacement is greatly reduced under the same load compared with that of the contrast bamboo beams. The loads PL/250 and PL/300, corresponding to the midspan deflections of L/250 and L/300 ( L is the span of the beams) of the composite beams, increase by averages of 3.36 times and 3.71 times, respectively, compared to those of the contrast bamboo beams. The load-bearing performance of the beams in the service state is greatly improved. Based on the equivalent cross-sectional stiffness calculated using the γ-method with a reduction of 0.80, the calculated results of the displacement are in good agreement with the test results.
