Based on the research to the stability variable cross - section beam, the bending defection differential equation of the variable cross - section beam in critical state of bucking is established. according to the edge condition of the structure, the differential equation is solved and bucking equation of variable cross - section beam is created. we can get the algorithm which can be used to calculate the equivalent inertia moment of the variable cross - section lattice structure when it is regarded as constant cross - section of solid web beam
對變截面格構式構件的穩定性計算進行了初步的研究，通過建立變截面構件臨界狀態下彎曲變形的微分方程，根據變形邊界條件，得到了兩端鉸支的變截面梁失穩特徵方程，提出了幾種特殊形式的變截面格構式構件等效為等截面實腹式構件時等效慣性矩的計算方法。 -
When whole analysis is carried through the beam - lattice method and bridge surface is made of box beams with one box and two cells, according to the principle of constant bending rigidity and every part revolving the same neutral axis, a box beam can be simplified into three beams in the places of corresponding webs. thus effective transfer of shearing force can be ensured, and global property can be reached through that of three beams, this kind of method is simple and is able to ensure engineering precision ; secondly, the paper is based on elastic theory, adopts finite element method and carries through the first kind stability analysis towards zhongshan no. one bridge
在選用梁格法進行整體分析時，遇到橋面系是單箱雙室的箱型梁時，按照抗彎剛度不變且各部分繞著同一中性軸的原則，將一個箱型梁在相應的腹板處簡化成3根梁，能夠保證剪力的有效傳遞，而且可以由這劃分的3根梁的性能得到箱型梁結構的總性能，這種方法簡便易行且能保證工程精度；其次，本文基於彈性理論，採用有限元法對中山一橋進行了第一類穩定分析。
