摘要
以试验数据为基础,通过反算得出受拉FRP筋的实际应力值,使用规范GB50608-2010和ACI440.1R-15公式分别计算了FRP筋混凝土超筋梁的FRP筋应力值与极限受弯承载力。研究表明,对规范GB 50608-2010计算FRP筋应力值进行1.2倍的放大调整,结果更接近于实际应力值,所得出的受弯承载力值与试验值吻合更好。
On the basis of experimental data, the actual stress value of the tensile FRP bars is calculated accordingly, The FRP bars stress and the ultimate flexural capacity of FRP reinforced concrete beams were respectively calculated using the formula of GB 50608-2010 and ACI 440.1R-15. The results show that , with the standard GB 50608-2010, calculated FRP tendon stress value of 1.2 times the magnification adjustment is closer to the actual stress value, the obtained value of the flexural capacity coincides with the test value better.
