Abstract

Reinforced concrete plays a crucial role in structural systems by providing strength and stability to buildings. Recent advancements in construction technology have introduced bamboo as an alternative reinforcement material to steel, due to its relatively high tensile strength (up to 253 MPa). However, bamboo's high cellulose content increases its vulnerability to fire. During building fires, structural elements may be exposed to temperatures between 800–1000°C for up to one hour. This study aims to investigate the effect of elevated temperatures on the axial load capacity and strain behavior of bamboo-reinforced concrete columns. Two reinforcement types were tested: (1) intact round bamboo with spiral steel stirrups, and (2) slatted bamboo with rectangular steel stirrups. All specimens were made using 25 MPa concrete with dimensions of 15×15×60 cm, and were exposed to 800°C for one hour before testing. Results showed that the round bamboo column with spiral stirrups sustained a maximum axial load of 247.6 kN (4.67% lower than analytical predictions and 59.83% lower than pre-fire values). The slatted bamboo column with rectangular stirrups held 233.2 kN (4.18% lower analytically and 61.78% lower than pre-fire values). Axial and lateral strain values varied slightly between specimens. This research highlights the structural viability of bamboo reinforcement under high-temperature exposure. Keywords: High Temperature Effect; Concrete Column; Bamboo Reinforced Concrete.

Abstract

In the midst of the growing construction projects, the use of composite materials is widely applied, one of which is CFRP (Carbon Reinforced Polymer) which has high tensile strength with low density. The selection of bamboo reinforcement as an alternative material to replace steel is because bamboo has a tensile strength value that is close to the tensile strength of steel. However, bamboo has a weakness in its compressive strength. Therefore, this CFRP restraint is expected to be able to overcome these limitations with the aim of analyzing the effect of CFRP restraint on bamboo reinforced concrete columns with normal concrete quality (25 MPa) and high concrete quality (50 MPa), using CFRP layers of 0 and 2 layers. The experiment was conducted by making 4 square-section concrete columns, using Apus bamboo as the main reinforcement and spiral steel as a binder. After the casting and drying process, the columns were given a CFRP layer according to the variation. The results of the study showed that CFRP restraint could increase the axial load capacity by 6.07% for normal quality concrete columns and 5.58% for high quality concrete columns. In addition, normal quality concrete columns with CFRP restraints also reduce the maximum deformation value by 47.6% and for high quality concrete columns it reduces the maximum deformation value by 87.3%.
