Compressive Behavior of Concrete Columns Confined with Bamboo Sheet Twinning Tubes

This study examines the compressive behavior of concrete columns confined with Bamboo Sheet twining tubes. Bamboo, as a natural fiber, is gaining attention as an eco-friendly alternative to synthetic materials. Bamboo sheet, is an emerging as promising materials for external confinement of concrete structures. Due to its superior strength-to-weight ratio, corrosion resistance, and durability, serves as an efficient alternative to traditional steel reinforcement in concrete structures. The objective of the project work is to assess the structural enhancement provided by Bamboo Sheet confinement under axial loading. Concrete specimens were wrapped with varying layers of Bamboo Sheet (6, 12 and 24 layers) to determine the optimal confinement configuration for strength improvement. Standard cylindrical specimens were tested under uniaxial compression using a Compression Testing Machine (CTM), and compressive strength variations were analyzed. The findings demonstrate the effectiveness of Bamboo Sheet confinement in enhancing load-bearing capacity, highlighting its potential as a sustainable and high- performance reinforcement solution for concrete columns in structural applications.
