中文摘要：

在型钢再生混凝土梁抗剪承载力试验结果的基础上，依据GB50068--2001《建筑结构可靠度设计统一标准》，采用Monte—Carlo法对型钢再生混凝土梁抗剪承载力进行了可靠度分析，主要分析了剪跨比、再生粗骨料取代率、配箍率、型钢腹板配钢率、再生混凝土强度等级以及钢材强度对型钢再生混凝土梁抗剪承载力可靠指标的影响。分析结果表明：在所分析参数范围内，型钢再生混凝土梁的抗剪承载力可靠指标均能满足现有规范要求，可用于实际工程。同时分析结果也表明，其可靠指标随剪跨比及再生粗骨料取代率的增大而减小；随配箍率和型钢腹板配钢率的增大而增大；随再生混凝土强度等级和钢材强度的增大而增大。分析结论可为型钢再生混凝土梁的设计和应用提供一定的参考。

英文摘要：

Based on the test results of shear capacity of steel recycled aggregate concrete beam and according to ＂Unified Standard for Reliability Design of Building Structure＂ （ GB 50068--2001 ） , the Monte-Carlo method was used to calculate the reliability of shear capacity of steel recycled aggregate concrete beam. The influences of shear- span ratio, replacement rate of recycled aggregate, stirrup ratio, steel ratio of webs, strength grades of recycled concrete and steel strength on the reliability of steel recycled aggregate concrete beam were studied. The results show that the reliability indexes of shear capacity of steel recycled aggregate concrete beam can meet the demand of existing code in the range of studied parameters. And it can be used in practical project. The results also show that the reliability indexes decreased with the increase of replacement rate of recycled aggregate and shear-span ratio. The reliability indexes increased with the increase of stirrup ratio and steel ratio of steel webs and also increased with the increase of recycled aggregate concrete strength grade and steel strength. The conclusions can provide reference for the design and application of steel recycled aggregate concrete beam.
