約束支座
英文
restrained support-
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。This paper analyses the impacts of different restrains, different loads and different pre - stress value of cable on the natural vibration frequency, damping ratio and mode of structure
