中文摘要：
对钢丝网水泥砂浆加固钢筋混凝土梁高温后抗弯性能进行试验，研究受热温度对钢丝网水泥砂浆加固钢筋混凝土梁高温后抗弯性能的影响规律。研究结果表明：采用钢丝网水泥砂浆加固法能有效提高梁的抗弯刚度，减少跨中挠度；随着受热温度的升高，钢丝网水泥砂浆加固梁的承载力有一定程度的降低，当受热温度在450℃以下时，加固梁承载力的降低不超过5％。也即采用钢丝网水泥砂浆加固混凝土梁具有良好的抗火能力。
英文摘要：
Flexural performance of RC beams reinforced by ferrocement was tested after different high temperature, and the influence law of the high temperature on flexural performance was analyzed. The results indicated that the reinforcement method of ferrocement could increase flexural rigidity of RC Beams, and it could decrease the deflection of midspan. The bearing capacity of reinforced RC beam decreased to some extent with the increasing of heating temperature; while the temperature was below 450 ℃ , the bearing capacity of reinforced RC beams decreased by less than 5 % . It indicated that RC beams reinforced by ferrocement had web flameresistant capacity.
