分析斜支承连续曲线箱梁桥时，采用考虑翘曲作用的曲线格子梁分析方法，应用矩阵位移法对具有约束支承形式的斜支承连续曲线薄壁箱梁桥进行分析，考虑到支座的约束条件并不与梁端弯曲角位移和扭转角位移的方向一致，引入支座节点坐标矩阵，使得梁端的位移未知量与斜支座约束方向一致，来计算单元刚度矩阵和单元节点力，然后按照矩阵位移法组集总刚并建立结构刚度方程，根据结构刚度方程即可求解未知的节点位移及杆端力，推导出任意截面处的内力计算公式。 - Concrete elastic modulus and concrete creep and shrinkage variety at different time are reckoned in by using time increment analysis method and concrete creep and shrinkage secondary force is calculated by using effective elastic modulus . bridge stability analysis program is developed on the base of structure matrix displacement method , the program adopts visual basic language , has friendly interface and visual data input windows . the buckling safety factor of currently finished structure is given as result
