| 摘 要： | 本文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,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能力可靠性提供了一个合理的评定方法。

| Abstract: | In this paper, shear strength reliability of multi-storey stone structures is studied by considering the randomness and the fuzziness of earthquake intensity and by considering the fuzziness of strength failure degree of stone structures. The seismic ground motion is simulated as a random pro-cess of stationary filtered nonwhite noise with fuzzy intensity. A Fuzzy safety criterion of shear strength of stone structures is eatablished based on the shear strength failure index. It provides an evaluation method for analysing earthquake - proof shear strength reliability of multi - storey stone structures. |
