| 摘 要： | 采用高强钢绞线网片-聚合物砂浆复合面层对一根经抗弯加固后的钢筋混凝土梁进行耐火试验。试验中按梁加固后抗弯承载力的80%加载,接近于加固前梁的抗弯承载力。试验结果表明,在不采取任何防火措施的情况下,采用该技术加固的钢筋混凝土梁能够满足规范规定的耐火极限要求。

| Abstract: | A fire resistance test has been carried out for a RC beam which is retrofitted with the composite cover of the high strength steel mesh and polymeric motar.The load maintains at 80% of the moment capability to the prototype beam,which is nearly equal to the original beam's capability.The test shows that strengthening materials and technology adopted can meet the requirement of fire protections regulated in the related criterion without any additional fire-prevent measures. |
