本节主要讲授与梁弯扭失稳相关的专业词汇、关键语法、复杂复合句的理解与翻译。
(1) 梁弯扭失稳弹性微分方程 (Differential equations for elastic LTB of beam)
(2) 形心与剪心 (Centroid and shear center)
(3) 影响梁弯扭失稳的参数 (Parameters affecting the LTB of beams)
(4) 梁弹塑性弯扭失稳 (Elasto-plastic lateral-torsional buckling of beams)
【简答题】
1. What are the conditions no need to check lateral-torsional buckling of beams?
【词汇英译汉】
1. shear centre
2. torsional angle
3. simply-supported beam
4. critical bending moment
5. loading point
【答案】
1. 剪心
2. 扭转角
3. 简支梁
4. 临界弯矩
5. 加载点
【句子汉译英】
1. 假设腹板厚度很小但有足够的刚度以保持它的形状,这样我们就可以得到相同的临界弯矩公式。
【答案】
1. Assume web thickness is small but have enough stiffness to keep its shape, then we have the same equation of critical bending moment.
