土硕桥梁工程作业汇总一、朱平老师：1.上一次交的作业再仔细做一遍，97 页例题 2-3-1，l。改成 2 米，计算最不利荷载；2.荷载横向分布系数计算，证明当各主梁惯性矩不相等时，偏心荷载对各主梁的总作用公式；3.主梁内力计算，107 页例题 2-3-5，计算 2 号主梁跨中截面、1/4 截面的最大弯矩和最大剪力，以及支点截面最大剪力；4.横隔梁内力计算，111 页例题 2-3-7，求跨中横梁在 1 号和 2 号主梁之间截面的弯矩，靠近 2 号主梁处支座右截面的剪力，荷载等级为公里—Ⅱ级；5.图如下求 3#主梁处，横梁弯矩影响线；3#、4#梁间，横梁弯矩影响线；1#主梁右侧，横梁剪力影响线；2#主梁右侧，横梁剪力影响线；6. 支座计算，这个大家都有拍照我就不详细写了。二、赵华老师作业作业一：视频可以到海飞和曹然那里拷1. How to cut giant pieces of steel fast with incredible precision to make the giant steel pieces fit together precisely? 2. Once the bridge deck of Millau bridge was created, how to put it in place? 3. How to make sure 36000 tons of bridge deck, which is pressed down the wedges, to be able to slide over one another to work effectively?4. How to construct the tallest piers (245m) ever built to specific point to a sky with a mm precision and to end up in the exactly right place?5. How to measure the distance? How GPS works?6. Why do we use cable stays in metal strands? Why it is better than steel chain? During the operation of the Millau Bridge, how to replace the metal strands without the bridge falling down?7. How to overcome the temperature expansion of steel bridge deck of Millau Brdige at the starting and the ending?8. How to overcome the temperature expansion of steel bridge deck of Millau Bridge at pier? And why it works effectively?9. How to overcome the temperature expansion of steel bridge deck of Millau Bridge at pier? And why it works effectively?10. Challenge question: Considering the seasonal temp...
