钢结构损伤诊断新技术综述

钢结构在玻璃幕墙、高层建筑、桥梁等领域得到了普遍运用,钢结构的损伤会带来一定的安全隐患和经济损失。必须采用相应的技术对结构进行诊断和评估,确定结构是否损伤,并判别损伤的程度和位置,以及结构使用功能和损伤的变化趋势,从而减少结构损伤带来的工程事故。本文对钢结构损伤诊断的最新技术进行了综述,钢结构损伤诊断技术能较早的发现损伤位置和估计损伤程度以及预测结构剩余寿命。

Nowadays, steel structure has been widely used in glass curtain wall, high-rise building, bridges and other fields. But the steel structural damage has also brought certain potential safety hazards and economic losses. Therefore using the corresponding technique for diagnosis and assessment of structures to determine whether the fault and damage of structure. Then it distinguishes the fault and damage degree and location, and the function and injury trends of the structure. So it can reduce the damage of structure engineering accident. Basing on referring to many literatures, it put forward the ideal health damage diagnosis system, new damage intelligent diagnosis method, so as to be found earlier by the damage location, injury extent and predicted the residual life of structure.
