Experimental evaluation of axial compression performance of precast panels from bamboo-reinforced concrete

Abstract

This research aimed to determine the performance of bamboo-reinforced concrete precast panels (BRCPP) subjected to axial compressive loads, validated using numerical simulations. Axial compressive load capacity, crack, and failure patterns were investigated and compared with steel-reinforced concrete precast panels (SRCPP) as a control. Eight panels were made with details of four BRCPP and SRCPP, having dimensions of 1200 × 400 × 50 mm3 each. The four SRCPPs consisted of two panels, produced in laboratories and two manufactured by local companies. The variations in bamboo reinforcement spacing were 150 mm and 180 mm, while the gap between steels was 180 mm, and panels were tested under axial compressive load. The results showed that the axial compressive load capacity of BRCPP with a bamboo reinforcement size of 12 × 12 mm2 at a distance of 150 mm was sufficient to meet the specifications of SRCPP panels produced by the local industry. Based on experimental, theoretical, and numerical simulation analysis, the performance of BRCPP showed suitability, making it a considerable choice, specifically for precast panels. The special advantage of BRCPP encompassed eco-friendliness and sustainability.
