Dissertation note: College of Engineering.-- Bachelor of science in civil engineering: Technological University of the Philippines, 2024. Summary: This study evaluates the viability of Kawayan-Tinik (Bambusa blumeana) as an alternative stirrup material in reinforced concrete beams, addressing environmental and economic challenges associated with traditional steel reinforcement. Bamboo’s high tensile strength, lightweight nature, and sustainability make it a promising construction alternative. Through a combination of finite element analysis (FEA) using Abaqus and Response-2000, and experimental testing, the structural behavior of beams with bamboo stirrups was compared to steel-reinforced beams in terms of flexural capacity, crack propagation, and force-displacement response. Results showed that internodal Kawayan- Tinik exhibited superior compressive strength (81.203 MPa) and tensile strength (193.64 MPa) compared to nodal sections. Control beams with steel stirrups outperformed bamboo- reinforced beams, with CB-2 achieving a peak load of 126.549 kN. Among bamboo- reinforced beams, BRC-3 with 150 mm stirrup spacing performed best, achieving a 53.65% increase in ultimate load (96.138 kN) and a 6.03% improvement in moment resistance (14.42 kN·m). BRC-3 also effectively controlled crack propagation, with flexural cracks initiating at 58.8 kN and reaching the ultimate load at 111.834 kN. These findings underscore the potential of bamboo as a sustainable reinforcement material. To enhance performance, optimizing stirrup spacing and node distribution is crucial. Future research should investigate staggered bamboo nodes for improved strength, the use of ready-mix concrete for consistent properties, modifications to shear span-to-depth ratios for better flexural failure analysis, and innovative stirrup designs to match or exceed steel performance.

This study evaluates the viability of Kawayan-Tinik (Bambusa blumeana) as an
alternative stirrup material in reinforced concrete beams, addressing environmental and
economic challenges associated with traditional steel reinforcement. Bamboo’s high tensile
strength, lightweight nature, and sustainability make it a promising construction
alternative. Through a combination of finite element analysis (FEA) using Abaqus and
Response-2000, and experimental testing, the structural behavior of beams with bamboo
stirrups was compared to steel-reinforced beams in terms of flexural capacity, crack

propagation, and force-displacement response. Results showed that internodal Kawayan-
Tinik exhibited superior compressive strength (81.203 MPa) and tensile strength (193.64

MPa) compared to nodal sections. Control beams with steel stirrups outperformed bamboo-
reinforced beams, with CB-2 achieving a peak load of 126.549 kN. Among bamboo-
reinforced beams, BRC-3 with 150 mm stirrup spacing performed best, achieving a 53.65%

increase in ultimate load (96.138 kN) and a 6.03% improvement in moment resistance
(14.42 kN·m). BRC-3 also effectively controlled crack propagation, with flexural cracks
initiating at 58.8 kN and reaching the ultimate load at 111.834 kN. These findings
underscore the potential of bamboo as a sustainable reinforcement material. To enhance
performance, optimizing stirrup spacing and node distribution is crucial. Future research
should investigate staggered bamboo nodes for improved strength, the use of ready-mix
concrete for consistent properties, modifications to shear span-to-depth ratios for better
flexural failure analysis, and innovative stirrup designs to match or exceed steel
performance.
