据课题任务书以及《建筑防火规范》、《建筑结构荷载规范》和《混凝土结构设计规范》等国家现行规范,规程完成了该课题建筑,结构,施工三个方面的设计,首先从总体出发,综合考虑和组织室内外的空间完成建筑平面,立面,以及剖面的设计;其次完成了一榀框架各结构构件的配筋设计,手绘结构施工图。整个设计方案在建筑、结构方面满足国家现行规范要求。
本设计对一榀框架,从结构选型入手,计算分析了该框架的荷载,利用分层法和D值法分别对框架结构在竖向荷载、水平风荷载作用下产生的内力进行了计算,通过内力组合,得出框架的控制内力,最后完成框架各构件的配筋计算并绘制了该框架的施工图。设计书中同时选算了框架的一个基础、楼梯,给出了基础、楼梯的配筋计算并绘制了施工图。

Abstract
The design is mainly on three parts of the subject,the building part, the structure part,and the construction part ,which based on the mission statement , "Building code for fire protection, ""building structures norms ","Design of Concrete Structures"and other existing national norms.Firstly,I departured from the general, having taken indoor and outdoor space and organization into conside ration,I completed the construction plan, Elevation design and profile design; followed the calculation of the reinforcement on structural members of each designed framework.Construction drawing was finished by hand. The design of the building meets the existing national specification.
In the design,I chose a framework, starting from the structure selection, when it came to the calculation load of the framework, the stratification method and evalue method were both introduced, respectively for the calculation of the vertical load, internal forces produced by horizontal wind loads .Through the combination of internal forces, the internal control forces of the framework were obtained , and finally the framework of the reinforcement calculation of each component were completed and construction drawings of the framework was drawn.In the design book, the reinforcement was calculated and construction drawings was drawn in both the foundation and the stairs selected.
Key words: Structural design; Framework; Reinforcement; Foundation
