【摘要】 本文针对某工程结构可靠性鉴定工作,研究桥式吊车使用中对厂房的荷载作用;利用时程曲线差分改进动态载荷识别的时域法,识别实验测得的某等高多跨单层厂房吊车刹车时程曲线,结果与荷载规范符合较好.本文介绍的实验技术和分析方法,对于地震区复杂结构可靠性鉴定和制定荷载设计标准都有实用价值.更多还原

【Abstract】 Aiming at the dynamic reliability appraisal, the dynamic load subjected to the bridge crane in a workhouse is studied. By using time series analysis for load identification good result has been obtained, which is in good agreement with the engineering code. It shows that the experiment and analysis are of practical value to making load design code, crane design, and construction reliability appraisal.更多还原
