Abstract
The subject of this paper is the sixth residential constructure of building of the shihua apartment house in the city of Lan Zhou. The building is on-site reinforced concrete frame structure of 6 storeys, which is C-class. The seismic fortification intensity is 8, and the driven cast-in-place pile foundation is adopted.
This design includes two parts: one is the architectural design and the other is structure design. The architectural design includes general layout, ground floor plane, typical floor plane and elevation . The corresponding construction documents drawing are given. The calculation of structural design has finished by hand, which is mainly on the
computation of internal force and reinforcing bars of a slice of transverse frame structure. The computation by hand includes gravity loading, frame rigidity, the internal force at the
horizontal and vertical loading action respectively, the lateral displacement at the horizontal loading action,the internal force combination, sectional reinforcing bars of beams and
columns, the elastic-plastic deformation checking at the extrem seismic action, the reinforcing bars of typical staircases and floor slabs, and pile foundation. The floor plane drawing,
detailed drawing and reinforcing bars drawing of foundation are given. And we have given the reinforcing bars drawing of typical slabs and staircases, typical beams and columns with plane-global representation, et al.
Keywords:Frame Structure; Earthquake-Resistance Design; Pile Foundation

第一章 绪论
毕业设计是我们在毕业前最后的学习和综合训练阶段，是深化、拓宽、综合学习的重要过程。因此毕业设计对提高我们的专业水平具有十分重要的意义。作为建筑工程专业的毕业设计，采用了住宅楼作为设计题目，具有广泛的应用性。
一幢建筑物的设计包括建筑设计和结构设计两部分。建筑设计除了要满足使用者的功能要求，还要考虑到经济、美观、实用等要求。本设计是在任务书的要求下设计的，在考虑了具体使用要求的前提下，还尽量考虑了防火、防滑、保温隔热等方面的要求。例如，在卫生间设置了防滑地板砖。另外，还考虑了采光、通风的要求，窗的面积的大小根据窗地比来确定的。此外，在设计中尽量考虑到功能合理，结构经济合理。 在结构设计计算中，结构设计需满足的要求有：安全性、实用性、耐久性等。这三方面总称为结构的可靠性，科学的设计方法就是在结构的可靠与经济之间选择一种最佳的平衡。
在本设计中采用了全现浇钢筋混凝土框架结构，由梁、柱构件通过结点连接构成，它既承受竖向荷载，又承受水平荷载。框架结构体系的优点是：建筑平面布置灵活，能够获得较大空间，加隔墙后也可做成小房间；建筑立面容易处理；结构自重较轻；计算理论比较成熟，通过合理设计，框架本身的抗震性能较好，能够承受较大的变形；在一定高度范围内造价也较低。由于框架结构的构件主要是梁和柱，所以梁、柱的尺寸都不能太大，否则影响使用面积，因此框架结构的侧移刚度较小，水平位移大，这是它主要的缺点，并因此限制了框架结构的建筑高度。在高层建筑中，梁、柱必须做成刚接，梁的跨度受到梁断面尺寸的限制，柱断面的尺寸要根据所承受的轴力和弯矩的大小确定，在地震区，柱的断面尺寸还受到轴压比的限制。
在本设计中，建筑物位于甘肃省兰州市，地震设防烈度为八度第二组，层数为六层，综合各种结构体系的优缺点及设计的要求，从而选择了框架结构。另外，本设计依据地形条件及土层的承载力把基础设计为桩基础，采用的是大直径人工挖孔灌注桩。这种基础在多层建筑设计中用得比较广泛，它的承载能力好，不容易下沉或偏移，而且比较经济。
