工业设备的震害预测研究

Study on the Prediction of Seismic Hazard of Industry Equipment

综合考虑地震作用和结构材料的随机性 ,运用概率论的知识建立了地震作用下钢铁工业设备各种破坏形式的极限状态方程 ,并求出了对应于某种地震烈度 ,设备出现各种破坏状态的概率。在此基础上 ,通过模糊综合评判的手段提出了工业设备的震害预测方法 ,并编制了相应的软件。此种方法的建立使设备抗震预测变得方便、可行。

On the basis of random property of seismic load and structural material, the limited state equation for industry equipment under seismic load is established referring to probability knowledge. The probability of all kinds of damage state under corresponding seismic intensity is also worked out By the technology of comprehensive fuzzy judgement, the method for the prediction of seismic hazard is presented, and a relevant program is compiled. The establishment of this method makes the prediction of seismic hazard feasible and convenient.
