| A Theoretical Problem in Obtaining Solution for Curved Bridge by Traditional Differential Equation |
| 摘要 |
| 在假定平曲線梁的平面內(nèi)及平面外彎曲符合直梁的物理關(guān)系，平曲梁的扭矩與扭率的關(guān)系與直梁相同的條件下，根據(jù)微分幾何理論，推導(dǎo)平曲線梁橋微單元軸向應(yīng)變、彎曲曲率增量、扭轉(zhuǎn)曲率與梁段單元位移、扭轉(zhuǎn)關(guān)系的幾何微分方程，構(gòu)建曲梁的微分物理方程。理論分析結(jié)果表明：微分 |
