混凝土结构设计原理题目及答案3教程文件

一.填空题

1．在混凝土及钢筋混凝土结构中，混凝土主要用以( 承受压力), 因而研究混凝土的（抗压强度）是十分必要的。p6

2.混凝土的变形可分为两类：一类是在荷载作用下的（受力变形），另一类是（体积变形）p14

3. 判断一个界面在计算时是否属于T形截面是看（混凝土受压区的形状）P92

4.减少摩阻损失的措施有（采用两端同时张拉）（对钢筋进行超张拉）P279

5.（碱骨料反应）是混凝土结构的“癌症”。P61

6. 为防止梁的斜截面破坏，通常在梁内设置（箍筋）和（弯起钢筋），以增强斜截面的抗拉能力。P109

7.钢筋混凝土构件在弯矩和扭矩共同作用下的破坏特征及承载力与（扭弯比），（构件截面尺寸），（配筋形式及数量）等因素有关。P217

8.预应力混凝土受弯构件在预施应力阶段，梁将受到（预加力）和（自重）的共同作用。P291

9.锚下局部承压构件的承载力由两部分组成，一是由（混凝土）提供的局部承压承载力，二是由（间接配筋）提供的局部承压承载力。P314

10.在计算锚下局部承压的承载力时，计算底面积的取值时，应采用（同心对称）原则。P314

二．判断题

1.混凝土受到的压应力越大，其徐变变形越大。（对）p23

2.不管受拉钢筋在什么位置，只要是T形截面梁，就一定要按T形截面计算；（错）

P92

3.根据钢筋混凝土梁的配筋情况，正截面破坏形式可以归纳为适筋梁塑性破坏、超筋梁脆

性破坏、少筋梁脆性破坏。（对）p74

4.对钢筋冷拉可提高其抗拉屈服强度和延性；（错）p31

5.在结构抗力R与荷载效应S满足S>R时，结构处于安全可靠状态；（错）p43

6、在混凝土抗压强度的试验中，在试件表面和压力机的压盘之间涂一层油脂，其抗压强度比不涂油脂的试件低很多（对）p6

7、混凝土立方体试块的尺寸越大，立方体抗压强度越高。（错）p7

8《建混规》中规定在正截面纵向受拉钢筋的极限应变为0.01，表示钢筋的均匀伸长率不得大于0.01 （错）p105 9、预应力钢筋混凝土的有效预应力，其数值取决于张拉时控制应力和预应力损失。（对）p276

10、在设计预应力混凝土简支梁的截面时，在预应力相同的条件下，其抵抗外荷载弯矩是一定的，与内力偶臂z的变化无关。（错）p345

三.简答题

1.简述钢筋混凝土梁各构造及作用 p68

（1）纵向受力筋梁的主要受力筋协助混凝土承担压力。

（2）弯起钢筋主要用以承担主拉应力，并增加钢筋骨架的稳定性。

（3）箍筋除了承受主拉应力外，在构造上还起固定纵向钢筋位置的作用

（4）架立钢筋架立箍筋，固定箍筋位置，以防止因混凝土收缩及温度变化而产生的裂缝。

（5）水平纵向筋防止因混凝土收缩及温度变化而产生的裂缝

2.为什么说预加应力可以提高梁的抗剪能力？ P303

答. 主要由于轴向压力能阻滞斜裂缝的出现和展开，增加了混凝土剪压强度，从而提高了混凝土所承担的抗剪能力；预应力混凝土的斜裂缝长度比钢筋混凝土有所增长，也提高了斜裂缝内箍筋的抗剪能力。

3.无腹筋斜截面破坏的破坏形式有哪些？并简述各阶段的破坏特点。 P110

答: 梁斜截面破坏时的三种形态为：（1）斜拉破坏：发生在剪跨比m>3时，且梁内配置的腹筋数量过少时。破坏前斜裂缝宽度很小，破坏在无征兆的情况下发生，属于脆性破坏（2）斜压破坏：当剪跨比m<1时，随着荷载的增加，梁腹板出现若干条平行的斜裂缝，将腹板分割成许多倾斜的受压短柱，最后，因短柱被压碎而破坏（3）剪压破坏：当剪跨比1

4.粘结力产生的原因及组成只要有哪些？P35

1） 混凝土中水泥凝胶与钢筋表面之间的胶结力。

2） 混凝土结硬时，体积收缩，将钢筋紧紧握裹而产生的摩擦力

3） 钢筋表面凹凸不平与混凝土之间产生的机械咬合力。

5.预应力混凝土构件预应力的损失主要包括哪些？P277

答: 1）预应力钢筋与管道壁之间的摩擦1l σ；

2）锚具变形、钢筋回缩和接缝压缩2l σ；

3)预应力钢筋与台座之间的温差3l σ；

4）混凝土的弹性压缩4l σ；

5）预应力钢筋的应力松弛5l σ；

6）混凝土的收缩和徐变6l σ；

四．计算题

1．已知梁的截面尺寸为b ×h=200mm ×500mm ，混凝土强度等级为C25, f c =11.9N/mm 2，2/27.1mm N f t =, 钢筋采用HRB335，2/300mm N f y =截面弯矩设计值M=165KN.m 。环境类别为一类。求：受拉钢筋截面面积

解：采用单排布筋 mm h 465355000=-=

将已知数值代入公式 s y c A f bx f =1α 及

)2/(01x h bx f M c -=α得

1.0?11.9?200?x=300?s A

165?106=1.0?11.9?200?x ?(465-x/2)

两式联立得：x=186mm

A s =1475.6mm 2

Python3基础教程二(个人整理)

Python3 基本数据类型 Python 中的变量不需要声明。每个变量在使用前都必须赋值，变量赋值以后该变量才会被创建。 在 Python 中，变量就是变量，它没有类型，我们所说的"类型"是变量所 指的内存中对象的类型。 等号（=）用来给变量赋值。 等号（=）运算符左边是一个变量名,等号（=）运算符右边是存储在变量中的值。 多个变量赋值 Python允许你同时为多个变量赋值。例如： 以上实例，创建一个整型对象，值为 1，从后向前赋值，三个变量被赋予相同的数值。 您也可以为多个对象指定多个变量。例如： 以上实例，两个整型对象 1 和 2 的分配给变量 a 和 b，字符串对象 "zzzzz" 分配给变量 c。标准数据类型 Python3 中有六个标准的数据类型： ?Number（数字） ?String（字符串） ?List（列表） ?Tuple（元组） ?Set（集合） ?Dictionary（字典）

Python3 的六个标准数据类型中： ?不可变数据（3 个）：Number（数字）、String（字符串）、Tuple（元组）；?可变数据（3 个）：List（列表）、Dictionary（字典）、Set（集合）。 Number（数字） Python3 支持int、float、bool、complex（复数）。 在Python 3里，只有一种整数类型 int，表示为长整型，没有 python2 中的 Long。像大多数语言一样，数值类型的赋值和计算都是很直观的。 内置的 type() 函数可以用来查询变量所指的对象类型。 此外还可以用 isinstance 来判断： isinstance 和 type 的区别在于： ?type()不会认为子类是一种父类类型。 ?isinstance()会认为子类是一种父类类型。

新世纪大学英语阅读教程翻译 Unit 1 塞克哈尔觉得，事实就像太阳一样。大概没有谁能直视太阳而不眨眼，不觉眩晕。他发觉人际关系的精髓在于时时刻刻调和事实，避免冲突。他设定了一个特殊的日子——一年中至少有一天无论如何必须说实话。否则生命还有什么意义。他对这一天充满无数期待，也没有告诉任何人要做这个实验。这是个秘密的决定，一件永远不为人知的事。 首次尝试便从妻子准备的早餐开始。他对一道美味举筷不定，这可是妻子自认为的厨中之冠。“怎么啦？不好吃吗？”她问道。要是往常，为了照顾她的情绪，他肯定说：“没有，我吃饱了而已。”可今天他却说：“不好吃。我咽不下去。”看到妻子眉头紧锁，他对自己说：“没办法，事实就像太阳一样。” 第二次尝试是在教师休息室，一个同事走过来说：“某某死了听说了吗？觉得很遗憾吧。”“不觉得，”赛克哈尔回答。“他的确是个好人……”另一个还没说完。塞克哈尔就抢过来说：“好什么啊，对我他可是个刻薄、自私的家伙。” 塞克哈尔给三年级A班上最后一节地理课时，收到校长递来的便条：回家前请过来一趟。他自言自语道：“肯定是那些可怕的试卷。一百多份字迹潦草的男生的试卷；他已经消极怠工几个礼拜了，感觉头顶像是悬了一把利剑，随时都有刺下来的可能。” 下课铃响起，孩子们潮水般涌出教室。塞克哈尔在校长门口停了会儿，扣好上衣扣子；扣子也是校长经常训诫的目标。 他进了门，彬彬有礼地说了句：“晚上好，校长。” 校长抬起头看着他，十分友善地问道：“今晚有空吗？” 塞克哈尔回答：“答应过家里的孩子要出去……” “那，可以改天再带他们出去。现在跟我回家。” “噢……好的，校长，当然没问题……”然后怯生生地问：“有什么要紧事吗，校长？”“是的，”校长回答，像是在对自己笑……“你真的不知道我缺乏音乐天赋吗？” “噢，知道，校长……” “我一直在偷偷地学习和练习，今晚想让你听听我演唱。我约好了一个鼓手和一个小提琴手为我伴奏。这还是我的第一次正式演出，想听听你的建议。我知道你的建议弥足珍贵。”塞克哈尔的音乐品味无人不知。他是小镇里最令人生畏的音乐评论人。可他怎么也没想到，他的音乐爱好将它引入这层磨难……。“对你来说，有点突然是吧？”校长问。“我已经关上门花了不知道多少钱……”他们开始往校长家走。“上帝没能给我一个孩子，可至少没有剥夺音乐给我的慰藉，”他们边走校长边悲戚戚地说。他喋喋不休地说着音乐的事：如何完全因打发无聊起步；如何被音乐老师取笑，又被给予希望；他人生的雄心壮志又是如何在音乐的世界里达到忘我的境界。 一到家，校长就大献殷勤。他请塞克哈尔坐在红丝毯上，敬上几样碟中美味，在旁边忙来忙去像是招待上门女婿。他甚至说：“你务必完全放松去听。别为那些试卷烦心。”然后不无幽默的加了一句：“我会给你一周的时间。” “十天怎么样，校长？”塞克哈尔请求。 “好，同意，”校长慷慨地说。塞克哈尔彻底松了口气——他可以一天干掉十份，彻底除掉这件烦心事。 校长点上熏香。“营造点气氛。”他解释说。鼓手和小提琴手已经到位，坐在缅甸仰光进口的小毯子上等他。校长在两人中间坐下来，像音乐会专业演出一般，清清喉咙，起了调子又停下来问：“可以吗，卡亚尼？（塞克哈尔的姓）”塞克哈尔假装没听到校长叫他。校长继
