梁下總桁-
In chapter 5, by number value simulation calculation and experiment of one simple support beam, we will compare the magnitude of the coupling static and dynamic stress at each point on the girder under harmonic excitation, and so find conclusions such as : ( 1 ) there are so much correlations between structure damage and environmental effect and exterior excitation leads dominant effects in structure damage that we should consider static and dynamic stress together. ( 2 ) new intension design rules should be set up, according which the range of structure possible damage position should be estimated in advance
得到以下結論： （ 1 ）結構的破壞和環境的影響密不可分，外部激勵在結構破壞中發揮了重要的作用，應該將結構所受的靜力和動力一起考慮； （ 2 ）應該建立新的強度設計準則，並以此作為依據，對已知結構的可能損傷位置有預先的范圍估計，從而為損傷識別的準確定位提供理論依據。 -
