《一榀主框架以及楼面及屋面板进行截面设计及配筋计算》-毕业论文.doc

w 摘要 某集团综合办公楼，总共6层。根据建筑设计、抗震方面等的要求，确定合理的结构形式和结构布置方案，确定框架、基础的形式。根据要求采用了钢筋混凝土结构。 本设计中选取一榀主框架以及楼面及屋面板进行截面设计及配筋计算。首先根据框架布局确定各构件尺寸，进行恒载、活载及风荷载的统计。然后采用弯矩二次分配法进行竖向荷载作用下的结构内力计算，水平荷载采用D值法进行计算。之后进行内力组合分析，找出最不利的一组内力，进行构件计算。楼板采用弹性理论设计，并进行柱下独立基础的配筋设计。除此之外，还进行了楼梯的设计计算。最后，根据计算结果，按照相应的构造要求，绘制了结构施工图，并写出了相应的设计说明。 本设计的特点之一，运用了大学四年所学过的很多理论，计算中多种计算方法得到体现，如D值法，弯矩分配法等，使自己掌握了多方面的知识。 关键词：框架结构；结构设计；内力计算；弹性理论；荷载；钢筋混凝土 ABSTRACT A building of supermarket was designed in this paper.According to the supermarket design and the earthquake resistance,the reasonable structural scheme and structural foundation plan was determined. One lateral frame and slab was selected and calculated.First,depth and width of sections were determined,and dead load ,live load,wind load were determined.Then the internal forces of the structure under vertical load were calculated.The D-method was used for caculating the wind load.After the combination of internal forces,the most unfavorable combination of internal forces was identified.Then the necessary reinforcement in beams and columns was determined.The elastic theory was used for calculating slab.In addition,the single-foundation and combined foundation were designed.The stairway and canopy were also designed.Finally according to the calculated results and detail, blueprints of the structure had been completed. The advantage in this design was that many theories studied in university in four years was used.The many kinds of computational methods was manifested in the computation,like D-method,the moment assignment-method,delamination and so on,so which caused myself to grasp the various knowledge. Key Words: frame；structural design；internal force； elastic theory；lateral loads；reinforced concrete? 1 前 言 毕业设计是大学本科教育培养目标实现的重要阶段，是毕业前的综合学习阶段,是深化、拓宽、综合教和学的重要过程,是对大学期间所学专业知识的全面总结。通过毕业设计,可以将以前学过的知识重温回顾,对疑难知识再学习,对提高个人的综合知识结构有着重要的作用。通过毕业设计,使我们在资料查找、设计安排、分析计算、施工图绘制、口头表达等各个方面得到综合训练,具备从事相关工作的基本技术素质和技能。 目前，我国建筑中仍以钢筋混凝土结构为主，钢筋混凝土造价较低，材料来源丰富，且可以浇筑成各种复杂断面形状，节省钢材，承载力也不低，经过合理设计可以
