十层框架结构计算书.doc

PAGE PAGE i 摘要 本毕业设计工程名为：XXX综合办公楼 本设计为高层办公楼，采用框架结构，建筑面积10680.00m2，主体建筑层数为10层。地面一层设置为公用服务设施,如餐饮厅，收发室。三层以上标准层设置为大办公室和小办公室，并设有会议室。 本毕业设计主要完成下列内容：建筑设计部分和结构设计部分。 建筑部分结束后是结构部分，先进行截面尺寸估算，然后进行荷载汇集，设计主要进行了结构方案中框架3轴框架的抗震设计。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，进而按底部剪力法计算水平地震荷载作用下大小，进而求出在水平荷载作用下的结构内力（弯矩、剪力、轴力）。 接着计算竖向荷载（恒荷载及活荷载）作用下的结构内力，找出最不利的一组或几组内力组合。计算框架梁时要考虑强剪弱弯的原则，选取最安全的结果计算、配筋并绘图。本例设计按着安全适用的建筑方针，空间布置灵活，使用性强，安全合理。 关键词 高层办公建筑；钢筋混凝土；框架结构；承载力；梁；轴力；荷载 Abstract This design is the high level office building, uses the portal frame construction. The architecture area is 10680.00m2, and the main body of the building is ten stories. Ground establishes as the public servicing facility, including the communication room. an above key bed establishes for does in a big way the public office The design project for graduation is as follows: the determine of the architecture program and the determine of the structure. After the building partially had finished is the structure are partial, first carries on the section size estimate, then carries on the load collection, with delamination computation vertical Hollands when function endogenic force. The purpose of the design is to do the anti-seismic design in the longitudinal frames of axis3. When the directions of the frames is determined, firstly, the weight of each floor is calculated .Then the vibrate cycle is calculated by utilizing the peak-displacement method, then making the amount of the horizontal seismic force can be got by way of the bottom-shear force method. The seismic force can be assigned according to the shearing stiffness of the frames of the different axis. Then the internal force (bending moment, shearing force and axial force) in the structure under the horizontal loads can be easily calculated. After the determination of the internal force under the dead and live loads, the combination of internal force can be made by using the Excel software, whose purpose is to find one or several sets of the most adver
