摘要
根据可靠性理论,编制了基于Matlab软件的Monte Carlo计算程序,直接产生服从各相应概率分布函数的随机变量数组,从而使编程过程大为简化,解决了Monte Carlo直接抽样困难的难题。通过对16根CFRP加固混凝土实验梁受弯实验,得到了随机变量的统计参量。采用基于Matlab的Monte Carlo法完成了对CFRP加固混凝土梁抗弯可靠度的数值模拟。结果表明,计算可靠指标与基于实验的AFOSM法计算可靠指标一致,且计算简便快捷。
According to reliability theory, the author compiled the Monte Carlo calculating program based on Matlab software and solved the Monte Carlo direct sampling difficulty, Through the experiment of 16 CFRP strengthened RC beams, the stochastic parameters of random variables were obtained. The flexural reliability of CFRP strengthened RC beams were simulated with Monte Carlo method based on Matlab. The result shows that the reliability index calculated by Monte Carlo method and by AFOSM method agree well and the computing process is quick and efficient.
