摘要

采用不饱和聚酯树脂(UPR)砂浆对单向钢筋混凝土受拉区板的损伤进行修复。修补后RC板的承载能力是证明修复有效性的重要因素。屈服线理论(YLT)可用于估计拼缝RC板在集中荷载作用下的承载能力。通过与实验结果的比较，验证了该方法的有效性。结果表明，补片会改变屈服线的形成，主要是在补片区域附近施加集中荷载时。随后，对于加载点靠近补片区的楼板，YLT方法提供了更高的承载能力估计偏差。另一方面，YLT方法在加载点远离补片区域时能够准确地估计出承载能力。

Evaluation of YLT method to estimate the load carrying capacity of one-way patched reinforced concrete slab under concentrated load

An unsaturated polyester resin (UPR) mortar was applied to repair the damage to the tension zone's one-way reinforced concrete (RC) slabs. The load carrying capacity of the patched RC slab is of interest to justify the effectiveness of the repair. The Yield Line Theory (YLT) may be used to estimate the load carrying capacity of patched RC slabs under concentrated load. The results of the YLT are compared with the experimental results to evaluate the validity of the YLT method. The results confirm that patching alters the yield line formation, mainly when the concentrated load is applied close to the patching zone. Subsequently, the YLT method provides a higher load carrying capacity estimation deviation for slabs with a loading point near the patching zone. On the other hand, the YLT method estimates load carrying capacity accurately when the loading point is away from the patching zone.
