t-beam girder
解釋
丁字梁桁架-
( 3 ) it is known that load effect is not consistent with the section resistance incommon section continuous composite beam. a kind of composite beam with itsrational section size is suggested, which is consist of the t shape concrete beam andsteel girder. this kind of composite beam not only has enough carrying capacity, almost has same positive and negative resistance moment, but can decrease theamount of the steel
（ 3 ）分析可知連續組合梁的跨中、支座截面處荷載作用效應及截面抗力規律不匹配，本文提出了採用t形混凝土梁和工字鋼代替一般的混凝土板和工字鋼的組合梁截面形式，並給出了截面尺寸比例，能使正負截面抵抗矩接近，符合組合梁受力特徵，減少了材料用量，滿足承載力和剛度等要求。 -
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。 -
Reasons : firstly, sectional dimension is so little that torsional stiffness of single - beam is n ' t enough. secondly, protective layer thickness is too thin to protect concrete reinforced bar and reduce durability. lastly, each main beam is joined by cross girder and the more rigid of cross girder the more entirety of bridge
橋梁局部損壞較嚴重，主要原因是主梁截面尺寸過小、肋板過于薄弱，造成單梁抗扭剛度不足；保護層厚度不夠導致鋼筋外露引起銹蝕，降低了橋梁的耐久性；各主梁採用橫隔梁連接成整體，橫隔梁的剛度越大，橋梁的整體性越好，但調查結果顯示，實際情況中並不能達到理想的整體剛度。 -
This paper analyzes skew support continuous curved t girder bridge and skew support continuous curved box girder bridge that largely applied in practical engineers, adopting statically indeterminate simple - supported curved beam as basic structure
論文以超靜定簡支曲線梁作為基本體系，對在實際工程中廣泛應用的斜支承連續曲線t梁橋和斜支承連續曲線箱梁橋進行分析。 -
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。 -
For do n ' t delive the horizontal power, connect method adopt the double hingle connect, and made both girder just to deliver the horizontal power each other, and vertical power can change position, this the problem that the top bear armor plate beam do n ' t accommodate the increasing in speed had been resolved radical
為了不傳遞豎向力，連接方式採用雙鉸接，使兩孔梁只能相互傳遞橫向力，豎向可以變位，從而基本解決了上承式鋼板梁不適應提速問題。 -
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。
