摘要
冶金工业厂房钢结构在使用过程中经常需要进行检测鉴定和加固改造．为了保证安全生产、推广先进技术和提高厂房设备的管理水平，冶金部新颁布了冶金行业标准《钢结构检测评定及加固技术规程》YB9257－96．本文对该规程进行了全面介绍并对所涉及到的一些技术方法如有缺损钢构件承载能力的计算，吊车梁残余疲劳寿命的估计和荷载下焊接加固等做了详尽的解释说明．
The existing steel structures of metallurgical buildings are often to be inspected,assessed,strength- ened and reconstructed.In order to keep safe in production,apply advanced technique and improve management of building and equipment,the Ministry of Metallurgical Industry has published YB 9257-96 'Technical Specification for Inspection,Assessment and Strengthening of Steel Structures'.In this paper,YB 9257-96 is in-troduced,and some technique and methods involved are explicated such as analysis of members with defects, residual fatigue life estimate of crane girder,welding of structures under loading and so on.
