第十章 结构弹性稳定计算
一、判断题：
1、稳定方程即是根据稳定平衡状态建立的平衡方程。
2、压弯杆件和承受非结点荷载作用的刚架丧失稳定都属于第一类失稳。
3、在稳定分析中，有n 个稳定自由度的结构具有n 个临界荷载。
4、两类稳定问题的主要区别是：荷载—位移曲线上是否出现分支点。
5、静力法确定临界荷载的依据是结构失稳时的静力平衡条件。
6、能量法确定临界荷载的依据是势能驻值原理。
二、计算题：
7、用静力法推导求临界荷载cr P 的稳定方程。
8、写出图示体系失稳时的特征方程。
9、求刚架在反对称失稳时的稳定方程。 n 为常数。
10、求图示完善体系的临界荷载cr P 。转动刚度kl k r 2=，k 为弹簧刚度。
11、求图示刚架的临界荷载cr P 。已知弹簧刚度l EI k 33= 。
12、求图示中心受压杆的临界荷载cr P 。
13、用静力法求图示结构的临界荷载cr P ，欲使B 铰不发生水平移动，求弹性支承的最小刚度k 值。
14、用静力法确定图示具有下端固定铰，上端滑动支承压杆的临界荷载cr P 。
15、用能量法求图示结构的临界荷载参数cr P 。设失稳时两柱的变形曲线均为余弦曲线：y x h =-δπ(cos ).12提示：cos d sin22u u u u a b a b

" 那样你们还能做朋友。虽然她错了，但这没什么大不了的。金：你说得对。谢谢你的建议。 戴夫：不客气。希望事情会好起来。 P27 Section A 3a 亲爱的鸿特先生， 我的问题是我不能和我家人相处。我父母间的关系变得很困难。他们经常打架，我真的不喜欢那样。打架是他们唯一拥有的交流方式。我不知道是否我应该对他们说些什么关于这个问题。他们吵架的时候就像一大片黑色的云笼罩在我们家。我的哥哥对我也不是很好。他经常拒绝让我看我最喜欢的电视节目。相反，他可以看任何他喜欢的直到深夜。我认为这是不公平的。在家我经常感觉孤独和紧张。那正常吗？我能够做什么？一个伤心的十三岁的孩子 亲爱的正在伤心的十三岁的孩子, 在你这个年龄总是不容易的，有这些感觉也是正常的。为什么你不和你的家人谈论你的这些感觉呢？如果你的父母间有问题，你应该帮助他们。或许你在家可以多做些家务，让你的父母有更多的时间可以进行适当的交流。其次，你为什么不坐下来和你哥哥谈谈呢？你应该向他解释你不介意他一直看电视。但是他应该让你看你最喜欢的节目。我
希望事情将很快会变好。鸿特先生 P28 语法聚焦 你看起来很累。怎么了？昨晚我一直学习到半夜，因此睡眠不足。我该怎么办？你为什么不忘掉它呢？虽然她错了，但这没什么大不了的。他应该做些什么？他应该跟他的朋友谈一谈，以便他可以说他很抱歉。也许你可以去他家。我想我可以，但我不想让他吃惊。 P30 2b 也许你应该学会放松！近来，中国的孩子有时周末比上学日更忙，因为他们不得不上许多课外辅导班。他们中的许多人正在学习考试技能以便能进人一所好的高中，以后考上好大学。其他的学生在练习体育，以便可以参加竞赛并获胜。然而，这并不仅仅发生在中国。泰勒一家是个典型的美国家庭。凯茜?泰勒的三个孩子的生活很忙碌。凯茜说，“放学后，大部分的日子里我带两个儿子中的一个去练习篮球，带我的女儿去进行足球训练。然后，我要带另个一个儿子去上钢琴课。也许我能减少一些他们的活动，但我相信，这些活动对孩子们的未来是很重要的。我真的希望他们能够成功。”然而，疲惫不堪的孩子们直到晚上七点后才回家。他们很快吃完晚饭，然后就到做作业的时间了。琳达?米勒是一位三个孩子的母亲，她了解这样的压力。“在一些家庭中，竞争从很小就开始了，一直持续到子们长大她说，“妈妈们把孩子们送去上各种各样的课程。他们总是把他们和其他孩子比较。这太疯狂了。我认为这是不公平的。他们为什么不让孩子做回孩子呢?人们不应该对自己的孩子这么苛刻。” 医生说，太多的压力不利于孩子的发展。爱丽丝?格林医生说，所有这些活动都会给孩子造成很大的压力。“孩子们也应该有时间放松和独立思考。虽然想让孩子成功是正常的，但是拥有快乐的孩子更重要。”
