六层框架结构公司综合办公楼设计

摘  要
本设计是唐山市兴达房地产公司综合办公楼设计，建筑面积为4136.6 m2 ，共六层，建筑高度为23.4m，整体是钢筋混凝土框架结构。包括建筑设计，结构设计两部分内容。 建筑设计是在总体规划的前提下，根据设计任务书的要求，综合考虑基地环境、使用功能、综合选型、施工、材料、建筑设备、建筑艺术及经济等。最终确定设计方案，画出建筑施工图。
结构设计是在建筑物初步设计的基础上确定结构方案；选择合理的结构体系；进行结构布置，并初步估算，确定结构构件尺寸，进行结构计算。
本设计采用钢筋混凝土现浇框架结构。在进行荷载计算和构件截面估算后，选取一榀框架进行计算，用二次分配法算出内力，并对最不利活荷载和最不利内力进行分析，从而进行配筋计算。本设计基础形式采用柱下独立基础，楼梯为钢筋混凝土现浇梁式楼梯。整个方案设计基本符合设计和结构要求，具有一定的创造性和合理性。
总之，适用、安全、经济、使用方便是本设计的原则，两部分空间合理，连接紧凑，主次分明，使建筑空间的舒适度加以提高。

The Architectural and Structural Design of Xingda Real Estate Company Office Building of Tangshan City
Abstract
The design is entitled Xingda Tangshan City real estate company L-type office building
structural design. The office of the total construction area is about 4136.6, a total of six layers, building height of 23.4m ,the overall framework of reinforced concrete structures . Includes 2 contents,which is constructing design and structural design. Floor area is 4136.6 m2, the  total of six layers, building height of 23.4 m , the overall framework of reinforced concrete structures .The  prerequisite  of building  design takes off in over all planning, is comprehensive according to the requirement of design assignment certificate to consider base environment , making hardworking can , comprehensive type selecting, construction, material, building  equipment ，building artistic and economic etc.. Eventually, determine design scheme , draw building construction picture.
Structural design is the definite structural scheme on the foundation of building  preliminary design; Select reasonable structural system; Then carry out structure to arrange, and preliminary estimation and definite  structural component size  and carry out structural calculation.
This scheme adopts the cast-in-place frame structure of reinforced concrete. After carrying out load calculation and component section estimation select one redistribution act , with the calculate of iterative method force, and for the most unfavourable live load with most the force in disadvantage analyse , so, match tendon calculation. Scheme basic form takes off independent foundation with column, stairs are the cast-in-place beam type stairs of reinforced concrete. Entire scheme design accords with design and structural requirement basically, have certain creativity and reasonability.
In a word, it is suitable, safe, economic , use convenience is the principle of design, two minutes have reasonable space and compact connection, primary and secondary  distinct, make the comfortable degree of building space rise.

Key words:  reinforced concrete frame structure  seismic    design representative load value    internal force combination      redistribution act

 该建筑底层、二层为商店、饭店及银行，所需空间较大；三~五层为办公层，所需空间较小，故采用钢筋混凝土现浇整体式框架结构，该办公楼共6层，总高度为23.4m，层高均为3.9m，8度抗震。
