| 摘 要： | 通过对钢筋混凝土偏心受压柱(包括小偏心受压及大偏心受压柱)外围覆玻璃钢强度性能的试验,测得了偏心受压柱的荷载-曲率及荷载-挠度曲线以及柱在围覆玻璃钢后的强度,得出了外围覆玻璃钢对提高柱抗压能力和变形能力的贡献.最后通过综合理论分析及参考<混凝土结构设计规范>,提出了实用的计算公式.此外,还对加固施工所采用的材料及施工方法提出了一些建议,也提出了当前在加固工程中采用这种材料需解决的问题,为今后在加固工程中采用这种新材料作了一些有益的工作.

| Abstract: | The eccetricall loaded columns (including small and large eccentricall loaded column) covered with Glass Fiber Rein-forced Plastics (GFRP) were tested. The load-curvature and load-deflection curves and the strength of the columns were ob-tained. Through the columns covetal with GFRP and the columns without GFRP, the GFRP's contribution to the compressive strength and the deflection were thus knew. Finally, some practical design formulas were proposed based on the comprehensive theoretical analysis and the reqiorement by Chinese Code named GBJ10-89. Additionally , using this new ma-terial in a strengthening project some sugestions about how to select material and construction method were made. Also somemarketable conlusions are appreciatal for reference. |
