Abstract

Reinforced concrete is perhaps the most widely used building material in the world.  However, the materials used for reinforcement of concrete i.e. steel is quite expensive and scarcely available in the developing world. As a result, bamboo is considered to be a cheaper replacement with high tensile strength. This research investigated the structural behavior of bamboo-reinforced concrete slabs used for footplate foundation subjected to concentrated load. For this purpose, four different reinforced concrete slab panels were developed and analyzed. The influence of replacing steel with bamboo for the reinforcement of concrete slabs on their structural behavior was assessed by determining the load-deflection characteristics, the ultimate load, the stiffness, the ductility, the cracking pattern, and the energy absorption capacity. The results showed that in comparison to steel reinforced concrete slabs, the strength of 82% can be acquired by the bamboo reinforced slabs. Furthermore, ductility demonstrated by the two types of specimens was almost equivalent i.e. up to 93%. Those indicated that the structural behavior demonstrated by bamboo reinforced slabs is quite comparable to that of steel reinforced concrete slabs. Therefore, bamboo can prove to be a promising substitute for steel in concrete reinforcement. Future studies may further examine this opportunity.

Abstrak

Konkrit diperkuat ialah bahan pembinaan yang digunakan secara meluas di seluruh dunia. Namun, bahan yang digunakan untuk memperkuatkan konkrit seperti keluli agak mahal dan sukar didapati di negara sedang membangun. Oleh itu, buluh telah dianggap sebagai bahan pengganti yang lebih murah dengan kekuatan regangan yang tinggi. Penyelidikan ini mengkaji sifat struktur konkrit diperkuat oleh buluh yang digunakan untuk tapak plat kaki dalam beban tertumpu. Bagi tujuan ini, empat panel slab konkrit yang diperkuat telah dibangunkan untuk dikaji sifat strukturnya. Kesan penggantian keluli menggunakan buluh sebagai bahan diperkuat kepada konkrit ke atas sifat struktur telah dikaji untuk menentukan ciri beban-pesongan, beban muktamad, kekakuan, kemuluran, corak retakan dan muatan penyerapan tenaga. Keputusan menunjukkan bahawa berbanding dengan konkrit diperkuat keluli, 82% kekuatan telah tercapai dengan penggunaan buluh. Tambahan pula, kemuluran yang ditunjukkan oleh dua jenis spesimen hampir setara iaitu hingga 93%. Ini menunjukkan bahawa sifat struktur yang ditunjukkan oleh slab diperkuat buluh agak setanding dengan slab konkrit diperkuat keluli. Oleh itu, buluh berpotensi menjadi pengganti keluli dalam peneguhan konkrit. Kajian pada masa depan boleh mengkaji lebih lanjut peluang ini.

Kata kunci: Beban tertumpu; konkrit diperkuat buluh; sifat struktur; slab
