lattice of roof
解釋
車頂格架-
Optimal initial design of plane lattice structure with light roof
輕屋面平板空間網格結構優化初設計 -
If we want to monitor the damage of the span lattice roof structure, the wind - induced responses and identification of parameters become the important problems first of all, which also the key technique of the damage monitoring of the structure. the method of time domain parameter identification is superior to the method in frequency domain : the structural response is only needed to identify the parameters of the structure
時域參數識別方法具有頻域方法無可比擬的優點，僅僅需要結構的響應信息，便可實現結構的參數識別，尤其對于大跨空間網格結構，人為激勵往往有很多的弊端，因此，積極發展有效的時域參數識別方法，還是很有現實意義的。 -
Since long - span lattice roof structures are generally with whole rigidity and it ’ s characteristic of light, flexible and low damping. with the development of economy and progress of science and technology, more and more long - span roofs have been built, which have individual characteristics in architecture and structure
空間網格屋蓋結構因具有整體剛度好、質量輕、柔性大、阻尼小等特點，隨著經濟的發展，各種外形獨特、結構形式新穎的大跨度網格屋蓋結構大量涌現。 -
During the long active service time, the structure maybe presents all kinds of structural damage because such reasons as tired accumulating, environment corroding and natural calamity function, etc. in order to find those damages early, nip in the bud, and lower the damage of accidents, it is great meaning full to research the technique of online damage monitoring of the long - span lattice roof structure
結構在服役期間，由於疲勞累積、環境腐蝕及自然災害等作用，可能出現結構損壞，因此，為了能夠及時發現問題，防患於未然，把事故損失降到最低點，在結構正常使用情況下，對大跨空間網格結構進行在線損傷監測研究，就顯得極有現實意義。
