某五层办公楼结构设计

某公司办公楼设计

摘要

本设计研究的内容是xx公司办公楼。采用框架结构，主体结构为五层，主楼标高18.55m，总建筑面积4000.36m2。在设计中楼﹑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。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。

本设计主要包括建筑设计部分和结构设计部分。建筑设计部分主要包括建筑平面、立面、剖面的设计；结构设计方面包括了结构的布置、结构构件的配筋设计，具体有柱梁板设计、楼梯间计算、内力组合、框架配筋等方面。在确定框架布局之后，计算竖向荷载作用下的结构内力和水平荷载作用下的结构内力。进行内力组合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。

最后，使用专业软件和办公软件工具进行电脑输入，对手算的结果进行了分析和检查。最后依据计算结果，结合相应的结构构造要求，绘制结构施工图和建筑施工图，写出相应的设计说明以及结构设计计算书。

Abstract

The design of the study content is xx company office building. Using frame structure, the main structure is divided into five layers, the elevation of 18.55m, the total construction area of 4000.36m2. In the design of the building, roof were using cast-in-place reinforced concrete structure. The design principle of "practical, safe, economic, beautiful" design. According to the architectural design standard, carefully consider the various factors affecting the design. Strict compliance with the relevant professional standard, reference to relevant information and the latest national standards, is a comprehensive scientific considerations on all aspects of the design.

The design includes architectural design and structural design part. The design mainly includes building plane, elevation, section; structural design includes the reinforcement design of structural arrangement, structural components, specifically the column beam plate design, staircase, the combination of internal force calculation, the framework reinforcement etc.. In determining the distribution framework, internal force calculation of the structure internal force and the horizontal load function structure under vertical loads. Find a group or several groups of internal force combination of the most unfavorable combination of internal forces. Select the best safety results of the reinforcement and drawing.

Finally, the use of professional software and office software tools for computer input, the opponent is the results of the analysis and examination. Finally, according to the calculation results, the corresponding structural requirements, drawing construction drawing and construction drawing design, write the corresponding and structure design calculations.

Key Words：Frame structure; seismic; structural design; internal force calculation
