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.

竹筋混凝土预制板轴心受压性能的试验评价

本研究旨在确定竹筋混凝土预制板（BRCPP）在轴向压缩载荷下的性能，并通过数值模拟进行验证。研究了轴压承载力、裂缝和破坏模式，并与钢筋混凝土预制板（SRCPP）作为对照进行了比较。八块面板由四块BRCPP和SRCPP的细节制成，每块尺寸为1200×400×50 mm3。四个SRCPP由两块在实验室生产的面板和两块由当地公司生产的面板组成。竹筋间距的变化为150 mm和180 mm，而钢之间的间隙为180 mm，并在轴向压缩载荷下对面板进行了测试。结果表明，竹筋尺寸为12×12 mm2的BRCPP在150 mm的距离处的轴向压缩承载能力足以满足当地工业生产的SRCPP面板的规格。基于实验、理论和数值模拟分析，BRCPP的性能显示出适用性，使其成为一个相当大的选择，特别是预制板。BRCPP的特殊优势包括生态友好性和可持续性。
