base girder 中文意思是什麼
base girder
解釋
底梁-
Based on the research of influenced parameters on constant and varying depth solid web box girder before, the shear lag aroused by the parameters including width - span ratio, outstanding flange on base slab and the position of the tendons are further studied. the investigation show that shear lag values diminish along with the decease of width - span ratio and the departure from the symmetrical axis of anchor position, but outstanding flange is contrary to the former
在前人對等截面、變截面實腹箱梁剪力滯效應影響參數研究的基礎上，本文進一步對腹板開孔的連續箱梁的寬跨比、底板翼緣伸出以及預應力錨固位置改變等參數對箱梁剪力滯的影響進行研究。 -
2 ) the value of base frequency, which is the first order vertical - bending vibration, is bigger in box girder bridges than those of t - beams. it shows that the vibration performance of box girder bridge is better than t - beams. 3 ) when considering the shear deformation of beam, the vibration frequency calculated by is bigger than those not considering the shear deformation
T型梁的基頻為橫向振動，而整體箱梁的基頻為豎向彎曲振動；整體箱梁的一階豎彎振動的頻率比t型梁得到了提高；整體箱梁的動力性能優于t型梁；考慮剪切變形后，梁的自振頻率降低，對于整體箱梁其降低值接近於5 ，在分析時不應忽略。 -
Arch dam, which is fastened to the base rock, is a high _ order, hyperstatic, spacial body case structure. it has not only arch function but also girder function, but its main loads are passed to each dam abutment by means of arch function
拱壩是固結于基巖的高次超靜定空間殼體結構，既有拱作用又有梁作用，其主要荷載是通過拱的作用傳到兩岸壩肩。 -
The different altitude up to base plate and distance between suspension girder has been set up and it lead to different damping ratio. lots of experiment is done in order to find optimum altitude and distance of suspension girder
研究發現，不同懸柵設置高度，不同柵條間距時產生的消能效果不同，並對此用模型試驗進行了最佳懸柵高度及柵條間距的優化分析。 -
Displacement method in structural mechanics and generalized grillage analogy method are combined to analyze skew support continuous curved t girder bridge, when calculating inner forces of a single curved beam, calculate its deformation, then at the base of basic principle of generalized grillage analogy, derivates calculating equations of load lateral distribution and inner forces of skew support continuous curved t girder bridge
對斜支承連續曲線t梁橋進行分析時，採用結構力學的位移法與廣義梁格法相結合，在求解單根曲線梁內力的同時，求得其變形，在此基礎上利用廣義梁格法基本原理，進行荷載橫向分佈及內力計算，推導出斜支承連續曲線t梁橋的內力與荷載橫向分佈計算公式。 -
At last the results obtained are compared with those of t - beams, which shows : 1 ) the base frequency of t - beam and box girder bridge is different not only in the value but also in vibration direction
通過與此無關t型梁自振特性的結果進行比較，得出了一些重要結論：從t型梁到整體箱梁，梁的基頻發生了改變。
