试题解析

力矩分配法

用一般的力法或位移法分析超静定结构(见杆系结构的静力分析)时,都要建立和解算线性方程组。如果未知数目较多,计算工作将相当繁重。H.克罗斯于1930年在位移法的基础上,提出了不必解方程组而是逐次逼近的力矩分配法。它在1930年发表在ASCE期刊,该方法仅考虑弯曲效应,忽略轴向和剪切效应。 从20世纪30年代到电脑开始广泛应用于结构设计和分析中,力矩分布法是最广泛应用的方法。

Passage 2It's no surprise that Jennifer Senior's insightful, provocative magazine cover story,"I love My Children,I Hate My Life", is arousing much chatter-nothing gets people talking like the suggestion that child rearing is anything less than a completely fulfilling, life-enriching experience. Rather than concluding that children make parents either happy or miserable, Senior suggests we need to redefine happiness: instead of thinking of it as something that can be measured by moment-to-moment joy, we should consider being happy as a past-tense condition. Even though the day-to-day experience of raising kids can be soul-crushingly hard, Senior writes that "the very things that in the moment dampen our moods can later be sources of intense gratification and delight."The magazine cover showing an attractive mother holding a cute baby is hardly the only Madonna-and-child image on newsstands this week. There are also stories about newly adoptive-and newly single-mom Sandra Bullock, as well as the usual "Jennifer Aniston is pregnant" news. Practically every week features at least one celebrity mom, or mom-to-be, smiling on the newsstands.In a society that so persistently celebrates procreation, is it any wonder that admitting you regret having children is equivalent to admitting you support kitten-killing? It doesn't seem quite fair, then, to compare the regrets of parents to the regrets of the childless. Unhappy parents rarely are provoked to wonder if they shouldn't have had kids, but unhappy childless folks are bothered with the message that children are the single most important thing in the world: obviously their misery must be a direct result of the gaping baby-size holes in their lives.Of course, the image of parenthood that celebrity magazines like Us Weekly and People present is hugely unrealistic, especially when the parents are single mothers like Bullock. According to several studies concluding that parents are less happy than childless couples, single parents are the least happy of all. No shock there, considering how much work it is to raise a kid without a partner to lean on; yet to hear Sandra and Britney tell it, raising a kid on their "own"(read: with round-the-clock help) is a piece of cake.It's hard to imagine that many people are dumb enough to want children just because Reese and Angelina make it look so glamorous: most adults understand that a baby is not a haircut. But it's interesting to wonder if the images we see every week of stress-free, happiness-enhancing parenthood aren't in some small, subconscious way contributing to our own dissatisfactions with the  actual experience, in the same way that a small part of us hoped getting "the Rachel" might make us look just a little bit like Jennifer Aniston.Which of the following can be inferred from the last paragraph?
