摘 要

 本工程为杭州市某教学楼工程，采用框架结构，主体为四层，本地区抗震设防烈度为6度，近震，场地类别为II类场地。基本风压0.45KN/M，基本雪压0.45 KN/M。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。根据结构与建筑的总体与细部的关系。
    本设计主要进行了结构方案中横向框架第6轴抗震设计。在确定框架布局之后，先进行了竖向荷载作用下的结构内力计算，利用分层法计算各层的弯矩，再进行框架组装，进而求出在竖向荷载作用下的结构内力（弯矩、剪力、轴力）。接着计算水平荷载（风荷载）作用下的结构内力，采用D值法计算。然后找出最不利的一组或几组内力组合。 选取最安全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，本设计采用桩基础，对基础承台和桩进行了受力和配筋计算。
 整个结构在设计过程中，严格遵循相关的专业规范的要求，参考相关资料和有关最新的国家标准规范，对设计的各个环节进行综合全面的科学性考虑。总之，适用、安全、经济、使用方便是本设计的原则。设计合理可行的建筑结构方案是现场施工的重要依据。

ABSTRACT

 This works for a teaching building project in Hangzhou, a framework structure for a four-storey main, in the region earthquake intensity of 6 degrees near Lan site classification as Class II venues. The basic Pressure 0.45 KN / M, basic snow pressure 0.45KN/M. Floor roof were using cast-in-place reinforced concrete structure.
 The design and implement "practical, security , economic, aesthetic," the design principles. With the architectural design, design seriously consider the influence of the various factors. According to the structural and architectural detail and the overall relationship.
The design of the main structure of the program horizontal framework 6-axis seismic design. In determining the distribution framework, the first layer is a vertical load of the structure of internal force calculation, Then calculated
 the moment with a layered of approach , and framework for further assembly, obtained in the vertical load of the structure of internal forces (moment, shear, axial force). Then calculation of the level load (wind load) under the structure of internal forces, a D value method.. Identify the most disadvantaged group or an internal force several combinations. Select the best safety results of the reinforcement and Mapping. In addition, the structure of the program indoor staircase design. Completion of the platform boards, boards of the ladder, platform beam component and the reinforcement of internal forces calculation and construction mapping. On the floor reinforcement calculation, the use of pile foundation design, foundation and pile caps for the force and reinforcement calculation.
 The whole structure of the design process, in strict compliance with the relevant professional standard, reference to relevant information and the latest national standards and specifications, and design of the various components of a comprehensive scientific considerations. In short, application, security, economic and user-friendly design is the principle. Design reasonable and workable structure of the program is the construction site of the important basis for the construction.
