is one of the practical form of values. The so-called values refers to the objective things are of no value and the value of fundamental perspective. Different values, peoples behaviour, attitudes, ways are different. People-oriented focus on human value and reality, we need the broadest masses as values. Adhere to people-oriented values, is to make the economy more development, improve democracy, cultural prosperity, and live a happier; is deeply concerned that human development and human values, development of social and human development of rational unified, insisted in the material civilization, political civilization and spiritual civilization in the overall advancement of Socialist civilization to a higher level. Also want to see that persons value is not only meet your needs, also is to meet the needs of others and the community. Adhere to people-oriented, to strongly advocate every community member, serve others, beneficial to the community of people. The so-called Outlook, attitude is on the record, including who, how to create a record of achievements, how to evaluate performance, and so on. What values, what kind of Outlook. Adhere to people-oriented Outlook, is on the premise of respecting the interests and power of people, creating a popular, warm hearts, steady heart performance, creating serve for one officer, the benefit of achievements, and overall construction of well-off society and promoting the all-round development of peoples performance. Achievement evaluation in both economic accomplishments, take another look at the effectiveness of social progress; changes in both urban and rural change; both hard environment to strengthen and take another look at the soft environment improvement momentum of development at present, depending on the potential for sustainable development. Leave people to talk about values are worthless and leave people to talk about Outlook is not what the performance. 4. people responded to the starting point of the question, and replied to questions point. Man is the sum of social relationships. We cannot leave the chichuanyongdu, housing, tourism and entertainment, entertaining, and even certain political, economic, cultural and social environment, and so on. Due to human needs, all walks of life will come into being. People create for their survival, and continue enjoying the results of the construction. Colorful in the transformation of the people of the world, community vitality in the creation of man. Therefore, any work we do, the starting point is human, what are people. Us speed up development, the core of which is to meet the needs of people, including survival needs, emotional needs and self-actualization needs. It should be noted that people are not machines, not the slave of an object, not to be controlled. People have their own personality, has its own personality, has its own dignity. Person in need of care, you need to understand, need to meet. It is said that in the agricultural society, people plant; in industrial society, man is an animal; the information society, return中南大学混凝土结构设计基本原理课程设计书姓 名： 陈垚宇 班 级： 工程管理1101班学 号： 指导老师： 杨剑 课程设计任务书铁路桥涵钢筋砼简支梁设计1. 设计内容： 一钢筋混凝土工形截面简支梁，承受均布恒载g=48kN/m(含自重)，均布活载q=76kN/m，计算跨度12m（具体见下表），截面尺寸如下图所示。箍筋采用Q235级，按铁路桥涵设计规范（TB10002.3-2005）设计该梁。要求：（1）按抗弯强度确定所需的纵筋的数量。（2）设计腹筋，并绘制抵抗弯矩图和弯矩包络图，并给出各根弯起钢筋的弯起位置。（3）验算裂缝是否满足要求。（4）验算挠度是否满足要求。（5）绘梁概图：以半立面、剖面表示出梁各部尺寸。（6）绘主梁钢筋图：以半跨纵剖面、横剖面表示出梁内主筋、箍筋、斜筋、架立筋、纵向水平及联系筋的布置和主筋大样图。（7）材料表。砼钢筋梁跨度mC35HRB33512mNow, we are in a new historical stage of all-round construction of a well-off society. In perform duties, and carried out work of process in the, we to put people as a guide principles, and a test standard, efforts from masses most hope do of things do up, from masses most care of hot problem grabbed, from masses most not satisfaction of place modified up, not make nominal of formalism, not do grandstanding of cosmetic, to seeking of style, help masses share, is people benefit. (C) the investee people is not only an idea, it is a job requirement. Philosophy through to the people-oriented thought in the work of the Office, must be clear work objectives. Party Office in the city this year remains: Advanced civil strife, local brand. The County (City) Party Committee offices and units directly under the Office to hold high the banner of first to excellence, people-oriented requirements, strengthen the construction and management of the Office towards the work a higher level. Investee 1. political participation based on conspiracy to adhere to people-oriented, will be around to promote coordinationDevelopment events, great searchings. The 16 session of the partys scientific Outlook on development, is the new Central collective leadership to the development of connotation, development essentials, further deepen the essence of development and innovation, is our partys ruling idea a leap. At present, establishing and implementing the scientific concept of development has become the partys important work. As the Office of party Committee, working party should service center, initiative to claim leadership of the decision, the current focus is to focus on promoting comprehensive, coordinated and sustainable development with more suggestions, do more research, summarized the typical. One is drafted to raise the level of your presentation. Your presentation is the main Office of products, is the basic carrier staff service, is important to measure service levels. The quality of your presentation, mainly depends on how much we drafted a document recognized by the leadership, how many are listening to the people in favour of the report, how many paid dividends in the practical work. Improve presentation drafting level, requirements we accurate grasp led intent, General led care of work are to as understand, General led consider of problem are to in-depth thinking; requirements we highlight place features, put superior approach policy and local actual combined up, put presentation of theme thrust and masses of by thought by wants to combined up; requirements we seeks to streamlined clear, with simple of language expression deep of thought, with short of length hosted rich of connotation. Second, the survey results more. Investigation of the base, the road to success is something, is our for the Party Committees policy decision a good idea, an important part of a good staff. This year, to focus around industrial XING city, and farmers increase, and and manpower development, and seeking, major problem and foster advantage industry, and adjustment agricultural structure, and carried第一部分 主梁的设计计算为了简化计算，根据规范TB10002.3-2005规定，可以按照T形截面梁计算。对所给参考截面修改为如下所示： 选用的材料及其主要参数：梁的跨度,钢筋选用HRB335，混凝土选用C35，% 一 荷载和内力1. 均布恒载 2. 均布活载 3. 总荷载 二 简支梁内力计算计算简图如下1.A截面剪力弯矩2.B截面剪力弯矩3.C截面剪力弯矩4.D截面剪力弯矩5.E截面剪力弯矩三梁的纵向受力主筋计算 板的净保护层厚度取为35mm，梁的受力钢筋采用HRB335，查规范TB10002.3-2005，得,，混凝土采用C35,查规范TB10002.3-2005得，（弯曲受压）,；取(桥跨结构)。1. 配筋试算（跨中截面为控制截面）由于梁的高度为1900mm，高度较高，假设受力主筋按两排布置,根据修改过的梁截面：，根据T形梁截面设计经验公式：；可取32的钢筋10根，则其面积由规范TB10002.3-2005有：受拉区域的钢筋可以单根或两至三根成束布置，钢筋的净距不得小于钢筋的直径（对带肋钢筋为计算直径），并不得小于30mm。 因此可以得到梁的纵向主筋布置如下图： 四跨中纵向受力钢筋的应力验算1.首先假设中性轴在翼缘内 根据规范TB10002.3-2005，最小配筋率%，由上图可知，恰好和假设的相同。则%,300，由此可知中性轴在腹板内。2.在腹板内由解得：有以上验算可得，跨中主筋和混凝土的强度均满足要求。五腹筋的设计计算 剪力的最大值，对应的剪应力1.主拉应力的容许应力与设计原则 根据TB10002.3-2005，对于C35混凝土（）（1） 有箍筋及斜筋时主拉应力的最大容许值（2） 无箍筋及斜筋时主拉应力的最大容许值（3） 梁部分长度中全由混凝土承受的主拉应力最大值 由于主拉应力在之间，所以必须按计算设置腹筋，但主拉应力小于的部分梁段内，可仅按照构造要求配腹筋。(如下图所示)2.箍筋的设计计算如上图所示需要配置腹筋的长度为，箍筋采用Q235，有规范可得，采用10的双肢箍筋（），取。 箍筋除用以承受主拉应力外，还起到保持主要受力钢筋的正确位置和联系受拉及受压区的作用，因此，即使计算不需要设置箍筋，也应按构造要求设置。具体的箍筋配置方法见附图。3.斜筋的设计计算如上剪力图所示，斜筋承受的剪力为梯形出去由箍筋承受的矩形面积。所需要的斜筋总面积：需要弯起的根数,取根布置斜筋的时候，应使各斜筋承担斜拉力的大小相等，或与其截面面积成正比，斜筋一般与中性轴成45夹角，布置的同时应根据每个横截面至少交于一根以上的斜筋，要求前后斜筋的投影应搭接，并作适当调整。本设计中采用作图法（见附图）六跨中截面裂缝宽度验算 查规范TB10002.32005有：钢筋混凝土T形受弯构件截面受拉边缘的裂缝宽度验算公式：其中：K1钢筋表面形状影响系数。对于螺纹钢筋K1=0.8 M1活载引起的弯矩；M2恒载引起的弯矩。M全部计算荷载引起的总弯矩系数，对光圆钢筋取0.
