1、河南理工大学本科毕业设计(论文) 摘 要 摘 要 本工程为焦作市口岸物流服务设施建设项目办公楼,八层钢筋混凝土框架结构体系。建筑物的总高度为 32.7m,占地面积 964 2m 左右,总建筑面积 7710 2m左右。本建筑物抗震等级为二级,抗震设防烈度为 7 度,基本地震加速度 0.1g,耐火等级一级,建筑设计使用年限为 50 年。焦作地区基本风压 0.45 kN/ 2m ,基本雪压 0.4 kN/ 2m 。屋盖 和楼盖采用现浇钢筋混凝土结构。 本设计选取横向框架第 4 轴进行结构设计,并考虑了地震作用。在确定框架布局之后,先进行了层间荷载代表值的计算 ,接着利用顶点位移法求出自振周期,进而按
2、底部剪力法计算水平地震荷载作用的大小,从而求出在水平地震荷载作用下的结构内力(弯矩、剪力、轴力)。然后计算竖向荷载(恒载及活载)作用下的结构内力,并找出最不利的一组或几组内力组合,选取最安全的结果计算配筋并绘图。此外还进行了结构方案中的室内楼梯的设计,完成了平台板,梯段板,平台梁等构件的内力和配筋计算及施工图绘制。本设计采用独立基础,并对该基础进行了地基承载力、受冲切力承载力和配筋计算。 关键 词 :框架结构、地震作用、顶点位移法、内力组合、截面设计 河南理工大学本科毕业设计(论文) Abstract Abstract This project is the port logistics se
