摘要
通过考虑地震烈度的随机性和模糊性,以及石结构强度破坏等级界限的模糊性来研究多层石结构抗震抗剪能力的可靠性问题.将地震地面运动模拟为含有模糊烈度参数的平稳过滤有色噪声的随机过程,引入抗剪强度破坏指数,建立了石结构抗震抗剪能力的模糊安全准则,为研究多层石结构的抗震抗剪可靠性及其在抗震设计中的应用提供了一个合理的方法.
The authors studied the reliability of earthquake-resistance and shear-resistance of multistoried stone structure,by taking account of the randomness and fuzziness of earthquake intensity and the fuzzy boundaries of intensity damage scales of stone structure. A fuzzy safety criterion of quake-resistance and shear-resistance of stone structure was established by simulating the ground motion of earthquake to be a random process of stationary filtered colored noise with fuzzy intensity parameter and by introducing the damage index of shear strength. A reasonable method was thus provided for the study of quake-resistant and shearresistant reliability of multistoried stone structure and for its application to the aseismatic design.
