摘要

本设计为公司办公楼。占地面积993.83m2，建筑面积3975.32m2。主要进行建筑方案设计、结构设计。采用框架结构，主体为四层。本地区抗震设防烈度为7度，场地类别为III类场地，设计基本地震加速度为0.15g。楼﹑屋盖均采用现浇钢筋混凝土结构。 建筑方案设计主要根据任务书要求，结合建筑物使用功能，防火疏散要求及建筑人性化进行建筑方案设计。一、进行功能分区；二、进行空间组合；三、绘制建筑施工图。

结构设计简而言之就是用结构语言来表达所要表达的东西。结构语言就是从建筑及其它专业图纸中所提炼简化出来的结构元素，包括基础、墙、柱、梁、板、楼梯、大样细部图等等。然后用这些结构元素来构成建筑物或构筑物的结构体系，包括竖向和水平的承重及抗力体系，再把各种情况产生的荷载以最简洁的方式传递至基础。在结构设计中，作者根据经验公式先进行梁、板、柱的截面尺寸估算，再查相关规范确定恒荷载、活荷载、风荷载、地震作用。通过二次弯矩分配法、D值法、底部剪力法进行相关荷载的计算，确定最不利组合，确定现浇板、框架梁、柱可能出现的最大内力，从而进行截面验算和配筋计算。

ABSTRACT

The

design for the Office building. Covering an area of 993.83m2, building area of

3975.32m2. Adopts the frame structure, subject to four floors. Seismic fortification intensity of 7 degrees in the region, site class III class venues, design Basic acceleration of 0.15G. Floor, and roof are made of reinforced concrete structures.

According to the specification of the architecture design requirements, using functions with building, fire safety evacuation requirements and building user-friendly design. , 1, the functional area; 2, the space portfolio; 3, drawing construction plans.

In short, structural design uses structural anguage to express things. Structure of language is from construction and other professional drawings and are refined to simplify the structure of elements, including the foundation, walls and columns, beam, slab, the staircase, the map-like detail and so on .Then these structural elements are used to form the structural system of a building or structure, including load-bearing system of vertical and level of resistance, then all of the load in the most concise way transfer to basis. In structural design, the authors first formula for beam, slab, column, the section size estimates by experience, further invest to determine relevant norms which constant loads, live loads, wind loads, earthquake. By the second moment distribution method, D-value method and the base shear,the desgin calculated the associated load, and determined the most disadvantaged, and the largest internal forces of the frame beams and columns, then checked and crossed sections for reinforcement calculation.
