桥梁工程作业汇总

土硕桥梁工程作业汇总一、朱平老师：上一次交的作业再认真做一遍，97页例题2-3-1，l。改成2米，计算最不利荷载；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；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；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；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.Howtocutgiantpiecesofsteelfastwithincredibleprecisiontomakethegiantsteelpiecesfittogetherprecisely?2.OncethebridgedeckofMillaubridgewascreated,howtoputitinplace?3.Howtomakesure36000tonsofbridgedeck,whichispresseddownthewedges,tobeabletoslideoveroneanothertoworkeffectively?4.Howtoconstructthetallestpiers(245m)everbuilttospecificpointtoaskywithammprecisionandtoendupintheexactlyrightplace?5.Howtomeasurethedistance?HowGPSworks?6.Whydoweusecablestaysinmetalstrands?Whyitisbetterthansteelchain?DuringtheoperationoftheMillau7.HowtoovercomethetemperatureexpansionofsteelbridgedeckofMillauBrdigeatthestartingandtheending?8.HowtoovercomethetemperatureexpansionofsteelbridgedeckofMillau9.HowtoovercomethetemperatureexpansionofsteelbridgedeckofMillau10.Challengequestion:Consideringtheseasonaltemperaturevariationandbrakingforceofvehicleload,givesomesuggestiontodeterminetheheightofsplitposition(giventheheightofpier,thedimensionofpier(longitudinalxtransverse)).Hint:Consideringthebendingmomentsatthebottomofpier,thebuckling(ortheverticalstability)ofthepier.Principle:Foracable-stayedbridgewithhighpiers,thepiersmusthavesufficientlongitudinalstiffnessandflexibilitytosatisfytherequirementoflongitudinaldeformationcausedbytemperatureload,concreteshrinkageandcreep,andbrakingforce.Thelowerpartwasdesignedtobeasinglepierwithsufficientlongitudinalstiffness,andtheupperpartwassplitintotwopartswithappropriateflexibility.作业二：1.Howmanytypesofbridgesarethereforthetimebeing?Describeindetailthespanrangeoftypesofthebridges?2.Intermsofthefollowingdifferentspanlength(250m,500m,800m,
