為斜交格子梁橋的內力變形分析研究和工程設計提供了更簡便、有效的數值分析計算工具。When analyzing skew support continuous curved box girder bridge, curved grid girder analyzing method considering warping effect is applied. matrix displacement method is applied in analyzing skew support continuous curved thin - walled box girder bridge with restrained bearing. in order to convert original rigidity equations to structural rigidi ty equations that can be solved, bearing nodal displacement matrix can be introduced, then unknown quantities at the edge of beams can be consistent with the restrained directions of skew bearings, unit rigidity matrix and unit nodal forces can be gained. structural rigidity matrix can be composed according to matrix displacement method, so nodal displacements and inner forces on the end of the rod that are unknown can be gained calculating equations of inner forces on any cross - section can be solved
分析斜支承連續曲線箱梁橋時，採用考慮翹曲作用的曲線格子梁分析方法，應用矩陣位移法對具有約束支承形式的斜支承連續曲線薄壁箱梁橋進行分析，考慮到支座的約束條件並不與梁端彎曲角位移和扭轉角位移的方向一致，引入支座節點坐標矩陣，使得梁端的位移未知量與斜支座約束方向一致，來計算單元剛度矩陣和單元節點力，然後按照矩陣位移法組集總剛並建立結構剛度方程，根據結構剛度方程即可求解未知的節點位移及桿端力，推導出任意截面處的內力計算公式。In the process, we import the displacement method " s concept of replacement ahead, that is to say, we replace the unknown vectors with new unknown vectors to prevent the delivering and accumulation of errors. at the same time, we completed the skew bridge calculation procedure, and compared the calculation results with the results by the finite element software ansys, it proved the correctness and practicality of this procedure
在矩陣傳遞的過程中引入位移法中的前進代入的概念，即將未知向量不斷的以新的未知向量替換，以防止誤差的傳遞和積累。本文完成了斜交格子梁橋的內力計算程序，並將計算結果與採用有限元分析軟體ansys分析計算的結果進行了比較，驗證了程序的正確性和實用性。Generally, the skew bridge ' s calculation theories can be divided into three types : the category 1 is the plank theories method, such as the finite difference method, the finite element method and the finite strip method, etc ; the category 2 is the beam theories, such as the grid beam theories, the general grid theories, the rigid cross - beam method, the elastically - supported continuous beam method and the bar system analytical method, etc ; the category 3 is the practical method, such as the g - m revising method, the grid - beam simple method and ghali form coefficient method, etc
目前關于斜梁橋的計算理論和方法概括起來，大致可以分為三類：第一類為板理論方法，如有限差分法、變分法、有限單元法、有限條法等；第二類為梁理論法，如格構梁理論、一般格構理論、剛性橫梁法、彈性支承連續法、桿件結構的分析方法；第三類為實用計演算法，荷載橫向分佈的計算方法如g ? m修正法、格構梁的簡易法、 ghali表格系數法等。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。分享友人
