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
為計入混凝土彈性模量的變化及混凝土徐變收縮隨混凝土的齡期與外荷載加載時間不同而變化的影響，採用時間增量法對每個計算階段根據其階段內時步數進行循環，以計算時段內彈性應力、應變增量和徐變、收縮產生的應力應變增量，利用有效彈性模量法計算混凝土徐變收縮次內力，在此基礎上，結合結構矩陣位移法的基本理論編制開發了計入混凝土時效效應的高墩大跨徑橋梁穩定分析程序。 -
Accounting for the effects of imperfection and large displacement of arch, an approach for the stability analysis of arch bridge is presented ， and a program is developed to predict the nonlinear buckling of arch the elastic lateral stability of the jiefang arch bridge in guangzhou during the construction phases and operating periods after its completion is analyzed the results show that the effects of initial deflection and large displacements on the critical load of lateral stability are significant, and that once the initial deflection and large displacement are taken into account, the values of the safety factor are smaller than those obtained by linear buckling analysis
考慮拱肋初始撓度等缺陷的影響，採用桿系結構大位移分析的有限元方法，建立了拱橋非線性穩定的計算方法，並編制了相應的計算程序文中計算了解放大橋鋼管混凝土拱橋在施工階段及成橋后運營期間的彈性側傾穩定結果表明：考慮拱肋初始撓度和結構大位移影響后，拱橋的非線性側傾穩定安全系數比按線性穩定計算值低
