摘 要
本设计为某集团职工宿舍楼设计,建筑主体为4层框架结构。设计内容包括建筑设计部分和结构设计部分。建筑设计部分包括建筑平面图、立面图、剖面图以及建筑说明图。结构设计时取一榀具有代表性的框架进行设计。结构计算内容有荷载计算、内力计算、内力组合、截面计算等几方面。在确定计算简图之后,按照有关设计规范和规定,采用弯矩分配法计算竖向荷载(恒载及活荷载)作用下的结构内力,再进行重力荷载代表值的计算,接着利用顶点位移法求出自振周期,按底部剪力法计算水平地震荷载作用大小,用D值法求出在水平地震作用和风荷载作用下的结构内力(弯矩、剪力、轴力)。由所得的内力进行内力组合,再找出最不利的一组或几组内力组合进行梁、柱的截面设计。截面设计时考虑“强柱弱梁、强剪弱弯”的原则进行内力调整。接着进行楼板、基础的设计,楼板的设计采用双向板设计。基础采用桩基础,基础设计包括荷载计算、基础承载力计算、冲切计算、基础配筋计算等等。

Abstract
The design of Dormitory building design of a group of workers, the main building is 4 story frame structure. The design content includes architectural design and structural design. Architectural design portion includes floor plans, elevations, sections and architectural description. Structure design is done with a representational framework design. Structure calculation contents include load calculation, internal force calculation, internal force combination, cross section calculation etc.. After determining the calculation diagram, according to relevant design standards and regulations, The internal force of the structure under vertical load (dead load and live load) is calculated by moment distribution method, the representative value of gravity load is calculated, the free vibration period is solved by vertex displacement method, the horizontal seismic load is calculated by equivalent base shear method, the structural internal forces (moment, shear, axial force) under the action of horizontal earthquake and wind load are solved by the D value method. The internal forces are combined, then the section of beam and column is designed according to the most disadvantaged group or several groups of internal force. The internal forces are adjusted according to the principle of "strong column and weak beam, strong shear and weak bending". Then the floor slab and foundation are designed. Slab is designed according to two-way slabs. The single foundation under column is used. The design of foundation include the calculation of load calculation, the calculation of bearing capacity of foundation, punching calculation and the calculation of foundation reinforcement etc..
Keywords: frame structure; architectural design; structural design; seismic design; foundation design ; pile foundation
