设计题目:某综合办公楼设计
摘 要
本工程是位于某市中天街西段的某综合办公楼,采用框架结构,主体结构七层,本地区抗震设防烈度为7度,场地类别为二类场地。夏季主导风向为东南风,冬季为北风,基本风压0.5kN/m2。基本雪压0.25kN/m2。楼﹑屋盖均采用现浇钢筋混凝土结构。本设计贯彻“实用、安全、经济、美观”的设计原则。按照建筑设计规范,认真考虑影响设计的各项因素。
本设计主要内容为手算选取了结构方案中横向框架第5轴结构设计。在确定框架布局之后,先计算竖向荷载(恒载及活荷载)和风荷载作用下的结构内力。然后进行了重力荷载代表值的计算,接着利用能量法求出自振周期,进而按底部剪力法计算水平地震荷载作用,进而求出地震作用下的结构内力(弯矩、剪力、轴力)。找出最不利的一组或几组内力组合。选取其中最不利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。对楼板进行了配筋计算。本设计采用独立基础,对基础进行了受力和配筋计算。
整个结构在设计过程中,严格遵循现行的国家标准规范,对设计的各个环节进行综合全面的科学性考虑。总之,安全、适用、经济、方便是本设计的原则。 关键词:框架结构,抗震设计,荷载计算,内力计算,计算配筋

ABSTRACT
The project is located in the western section of a city Zhongtian Street office building, using the frame structure, the main structure of seven storeys, the region seismic intensity of 7 degrees, site classification as second-class venue. Dominant wind direction is southeast wind in summer and winter from the north; the basic wind pressure is 0.5kN/m2. Basic snow pressure is 0.25kN/m2. The floor and the roof are made of cast-in-place reinforced concrete structure. The principle is \aesthetic\various factors affecting the design.
The design of the main contents was calculating the structure for the program 5th axis transverse frame structure design by hand. In determining the frame layout, First calculate the vertical loads (dead load and live load) and wind loads of structural forces. Then calculate the gravity load representative value, then calculate the vibration period by using the energy method, and then calculate the horizontal seismic load by using the base shear method, and then find the structure under seismic forces (bending moment, shear, and axial force). Identify the most unfavorable force of a group or several groups of force combinations. Select
one of the most unfavorable results calculated reinforcement and drawing. In addition, the structure of the program carried out in the interior staircase design, completion of the platform board, bench boards, beams and other components of the force platform and reinforcement calculation and construction drawings. Reinforcement calculation carried out on the floor. This foundation design uses independent foundation, Carried out on the basis of the force and Reinforcement.
In the design process the whole structure, strict compliance with existing national standards, all aspects of the design of comprehensive scientific considerations. In short, safe, suitable, economical and convenient is the design principle.
KEY WORDS: Frame Structure, Seismic Design,Load Calculation,Internal force
