宣化县某商业办公楼
摘 要
本工程为宣化县某商业办公楼工程，采用钢框架结构，主体为六层，本地区抗震设防烈度为7度，场地类别为II类场地。主导风向为西北，基本风压0.55KN/M，基本雪压0.25 KN/M。楼﹑屋盖分别采用现浇钢筋混凝土结构、组合结构、SP板。
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5轴抗震设计。在确定框架布局之后，先进行了层间荷载代表值的计算,然后按底部剪力法计算水平地震荷载作用下大小，进而求出在水平荷载作用下的结构内力（弯矩、剪力、轴力）。接着计算竖向荷载（恒载及活荷载）作用下的结构内力。是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，本设计采用独立基础。
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。

Xuanhua County commercial office buildingABSTRACT
This works for the Xuanhua County commercial office building, a Steel framework structure for a six-storey main, in the region earthquake intensity of 7 degrees near Lan site classification as Class II venues. Led to the northwest direction, the basic Pressure 0.55 KN / M, basic snow pressure 0.25KN/M. Floor roof were using cast-in-place reinforced concrete structures, composite structures, SP board.
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 5-axis seismic design. In determining the distribution framework, the first layer of representative value of the load, then at the bottom of shear horizontal seismic load calculation under size, and then calculated the level of load under the Internal Forces (bending moment, shear and axial force). Then calculate vertical load (constant load and live load) under the Internal Forces. 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, This design uses an independent foundation.
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.
KEY WORDS: Steel Frame Structure、Seismic Design、Load Calculation、Internal force calculation
