摘要
从结构破损分析着手 ,探讨了结构保护的思路、目标和方法。特别提出结构熵的概念 ,认为加强对环境的调控和改善人为因素对结构的正向作用 ,通过外界的负熵流的输入抵消系统内部正熵的产生并保证有一定负熵盈余 ,是结构保护的最基本原则。预计 2 1世纪的结构是高强、高效、长寿并具有自保护功能的新型结构。
By starting from structure failures,thinking,the object and method for structure protection are discussed In particular,a concept of structure entropy is presented and a fundamental principle for structure protection is put forward that it is necessary to control the environmental factors,to improve the positive action of human factors on structure ,to pledge surplus of negative entropy by inputting negative entropy from outward system It is predicted that the 21 century's structures be a new type of structures with high strength,high effectiveness and long term life and self protection capacity
