摘 要

本设计进行了AB、BC、CD跨横向框架的抗震设计。先确定框架布局，截面选型，进行层间重力荷载代表值的计算,再后来利用刚度法（修正后的抗侧移刚度）计算风荷载，顶点位移法求自震周期，按近似计算法计算水平地震荷载作用，进而求出在水平荷载作用下的力。再者就是计算竖向荷载作用下的内力，找出最不利的一组或几组内力组合进行设计。建筑图纸包括建筑施工总说明、建筑平面设计、立面设计和剖面设计；结构图纸包括结构施工总说明、结构平面布置、楼板、屋面板配筋图、手绘一榀框架的配筋图，之后又做了室内楼梯设计，其中包括了平台板、梯段板、平台梁等构件的内力和配筋计算。最后完成了基础设计及基础施工图的绘制。

Abstract

This design has carried on the AB, BC, CD across the seismic design of the horizontal framework. Make sure the frame layout, section selection, interlayer representative value of the gravity load calculation, and then using the method of stiffness (revised) resistance to lateral stiffness calculating wind load, the vertex displacement method since the earthquake cycle, according to the approximate calculation method to calculate horizontal seismic load, and then calculate the force under horizontal load. Moreover is under vertical load calculation of internal force, find out the most unfavorable to design a group or several groups of internal force combination. Architectural drawings including the construction of total, the building plane design, elevation and section design; Structural drawings including structure construction, structure layout, floor, roof boarding reinforcement figure, a cross reinforcement figure, then do the indoor stair design, including the flat pallet, bench board, platform beam component of the internal force and reinforcement calculation. Finally completed the foundation design and foundation construction drawing.
