In order to study the effect of externally bonded steel on the flexural properties of stone beams, the experimental study and numerical simulation method are used to analyze the deformation characteristics and bearing capacity of reinforced stone beams, and the influence of the amount of sticky steel and the secondary loaded on the bending performance are studied. The results show that the stone beams strengthened by external viscous steel have ductile failure characteristics; the anchoring of steel has a great influence on the bearing capacity and ductility of reinforced stone beam. The amount of sticking steel has a limited effect on the cracking load of stone beam, but it has great influence on yield load. With the increase of the initial load, the cracking moment of the reinforced stone beam is gradually reduced, and the yield bending moment is gradually increased.%为了研究外粘型钢法对石梁抗弯性能的影响,采用试验研究和数值模拟方法,对加面石梁的受力变形特点和承载 力进行了分析,并研究了粘钢量和二次受力对其受弯性能的影响.研究表明:采用外粘型钢法加固的石梁具有延性破坏特 征,角钢的锚固对加固石梁的承载力和延性有很大的影响;粘钢量对加固石梁的开裂荷载提高程度有限,但对屈服荷载影响 很大;随着初始荷载的增加,加固石梁的开裂弯矩逐渐降低,而屈服弯矩逐渐增大.
