1、土硕桥梁工程作业汇总-、朱平老师:1.上一次交的作业再认真做一遍，97页例题2-3-1,lo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，荷载等级为公里一II级；5.图如下Rk”-丄5"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

2、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.Howtocutgiantpiecesofsteelfastwithincredibleprecisiontomakethegiantsteelpiecesfittogetherprecisely?2.OncethebridgedeckofMillaubridgewascreated,howtoputitinplace?3.Howtomakesure36000tonsofbridgedeck,whichispresseddo
