摘要: 通過對鋼筋混凝土(RC)梁構件進行受損前后的受彎性能加固實驗研究,分析了實驗構件的破壞形態、裂縫分布、荷載-撓度曲線、鋼絞線的應變曲線以及極限承載力等.研究表明,普通RC梁在一般過火條件下,其抗彎承載力和剛度有一定程度的降低,而采用高強鋼絞線網-聚合物砂漿復合面層加固技術(SMPM)加固后,其加固效果顯著,承載力較過火梁顯著提高,可恢復到其過火前的水平.

Abstract: The failure modes, fracture distributions, load-deflection curves, strain curves of strands and ultimate bearing capacities of reinforced concrete (RC) beams before and after being fire-damaged were analyzed on the basis of experimental studies on the bending properties of the beams. It is shown that the flexural capacity and stiffness of the fire-damaged beam reduce in some degree. After strengthening with high-strength steel wire mesh and polymer mortar (SMPM) the bearing capacity of the fire-damaged beam increases significantly and can reach the level of the RC beam before burning.
