六层框架办公楼结构毕业设计

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, return2007届本科生毕业论文第一章 设计任务及基本要求1.1 设计原始资料1.1.1 工程概况该工程为六层办公楼，主体为现浇钢筋混凝土框架结构，占地面积为1310，建筑面积5240，建筑物共6层，底层层高5.1m，标准层层高3.6m，顶层层高4.5m，总高度25.5m，室内外高差0.450m，基础顶面距离室外地面1.05m，基础采用柱下独立基础。该办公楼主要以层为单元出租，每层为一个独立的单元，拥有接待室、会议室、档案室、普通办公室、专用办公室等。楼内设有两个电梯三个楼梯，主、次楼梯开间均为3m，进深均为6.6m，楼梯的布置均符合消防、抗震的要求。1.1.2 设计条件一、抗震设防烈度：7度设防，抗震设计分组为第一组，设计基本地震加速度值为0.1g；二、基本风压： 0.55KN/m2，B类粗糙度；三、雪荷载标准值：0.2KN/m2；四、结构体系：现浇钢筋混凝土框架结构。五、工程地质条件：拟建场地地形平坦，土质分布具体情况见表，II类场地土。地下稳定水位距地表-9m，表中给定土层深度由自然地坪算起。建筑地点冰冻深度-0.5m。表1-1 建筑地层一览表序号岩土深度土层深度（m）厚度范围（m）地基土承载力（kPa）压缩模量（mPa）1杂填土0.01.21.2-2粉土1.22.00.82005.03中粗砂2.04.82.83009.54砾砂4.815.010.235021.01.2 建筑设计任务及要求一、基本要求：满足建筑功能要求，根据已有的设计规范，遵循建筑设计适用、经济合理、技术先进、造型美观的原则，对建筑方案分析其合理性，绘制建筑施工图。二、规定绘制的建筑施工图为：1、底层、标准层及顶层平面图：比例 1：150（图1-1）2、主要立面图：比例 1：150（图1-2，图1-3）3、屋面排水布置图：比例 1：1504、剖面图：比例 1：1505、墙身大样及节点详图：比例 1：100及1：10主蒸汽管道和高温再热蒸汽管道分别从过热器和再热器的出口联箱的两侧引出，然后汇成一根母管，到汽轮机前再分成两根支管分别接入高压缸和中压缸左右侧主汽关断阀和再热关断阀。Now, we are in a new historical stage of all-round construction of a well-off society.

结构方案的确定考虑到现浇钢筋混凝土框架结构建筑平面布置灵活，能够获得较大的使用空间，建筑立面容易处理，可以适应不同房屋造型，故本设计采用现浇钢筋混凝土框架结构。3.1.2 基础类型的确定根据施工场地、地基条件、场地周围的环境条件，选择柱下独立基础。3.1.3 结构构件截面尺寸和材料的选择一、基础顶面设计标高的确定根据地质勘察报告的建议，地基持力层可设在中粗沙层上，该层距室外地面2.0m4.8m之间，现选用桩基础，故取基础顶面距离室外设计地面1.05m处。二、楼板厚度的确定根据平面布置，单向板的最大跨度为3m，按刚度条件，板厚为l/40=3000/40=75mm；按构造要求，现浇钢筋混凝土单向板的最小厚度为60mm；综合荷载等情况考虑，取板厚h=100mm.三、次梁截面尺寸确定根据平面布置，次梁的最大跨度为8100mm，次梁高h=(1/181/12)l=(1/181/12)8100=450mm1013mm，取h=700mm；次梁宽b=(1/21/3)h=(1/21/3)700=350mm233mm，取b=300mm 四、框架梁截面尺寸确定1、横向框架梁：横向框架梁的最大跨度为6600mm，横向框架梁高h=(1/81/12)l=(1/81/12)6600=825mm550mm，取h=750mm；横向框架梁宽b=(1/21/3)h=(1/21/3)750=375mm250mm， 取b=350mm 2、 纵向框架梁：纵向框架梁高h=(1/81/12)l=(1/81/12)6600=825mm550mm，取h=750mm；纵向框架梁宽b=(1/21/3)h=(1/21/3)750=375mm250mm， 取b=350mm 五、框架柱截面尺寸确定对于多层框架，无论从受力的角度，还是柱的净高而言，都以底层最为不利。底层层高H=5.1m，柱截面高度取h=(1/151/20)H=(1/151/20)5100=340mm255mm。又对于抗震设防烈度为7度，房屋高度为22.5m30m，即抗震等级为三级的框架结构，为保证柱有足够的延性，需要限制柱的轴压比，柱截面面积应满足下式：，其中，再扩大1.21.3倍，则，即，bc=hc=530mm，综合考虑取bc=hc=550mm。六、材料选择1、混凝土强度等级：除基础垫层混凝土选用C10，基础选用C25外，基础以上各层混凝土均选用C35。2、钢筋级别：框架梁、柱等主要构件的纵向受力钢筋选择HRB335级钢筋；构造钢筋、箍筋及板内钢筋选用HPB235。3.2
