摘要
本文对不能取样或切取试件进行试验的大型复合材料工程结构破损状态的承载能力评定问题进行了初步探讨,通过分析与比较,导出了基于“等代设计”思想的梁式结构的实用评定方法,为这类结构修复加固的前期评定提供了一种理论分析与技术实施的参考模式。
The preliminary investigation on the evaluation of load carrying capacity of large composite structures in engineering from which the samples can't be taken for tests in the damaged state is carried out in the paper. Through the analyses and comparisons, an actual evaluation method fitting to beam structures which is based on the 'replacing design' idea is developed, and a reference model of theoretical analysis and its being carried into practice, which is used in the preliminary evaluation of these types of structures when they are required for repair and reinforcement, is suggested.
