摘 要

商业楼根据设计要求为四层混凝土框架结构，在设计过程中，首先要从建筑的场地上考虑，要有合理的布局，符合规范的进出口通道，以及消防规范。其次从建筑设计角度而言，外立面的美观是不可忽视的。内在的空间布局及建筑规范等方面的知识也要相结合，对商业楼所具备的功能能更透彻的去了解，要在经济合理并符合国家的法律规范的情况下完成建筑设计。

本设计主要包括建筑设计和结构设计两部分。建筑设计包括：平面定位图设计、平面设计、立面设计和剖面设计。结构设计为框架结构设计，主要包括：结构选型，梁、柱、墙等构件尺寸的确定，荷载计算、横向水平作用下框架结构的内力和侧移计算、竖向荷载作用下横向框架的内力分析、内力组合、截面设计、基础设计。其中基础设计有包括基础选型、基础平面布置和地基计算等。

本设计过程中严格按照最新规范及相关规定进行设计，其中采用的计算方法均参照指导书籍。

关键词： 商业楼设计 框架结构 结构计算

Abstracts

This design implementation ‘practical , safe , economical and artistic’ the principle of design . According to the architectural design standard , considered earnestly affects the design each factor . According to structure and building overall and detail relations .

This design after determination frame layout , has carried on the level first the load generation of tabular value computation , extracts the wind load with the D value law the function , then uses the bending moment two methods of distribution to calculate the vertical load (dead load and live load) under the function structure endogenic force , and discovers most disadvantageous group of or a several group of endogenic force combination . Selects the safest result computation to match the muscle and to draw a chart . In addition has also carried on in the structure plan room the staircase design . Has completed the even platen , the carriage board , component and so on platform Liang endogenic forces and matches the muscle computation and the construction drawing plan . Carried on to the floor has matched the muscle computation , this design used the independent foundation.

The entire structure in the design process , the strict deference related specialized standard request , the reference correlation data and the related newest national standards standard , carries on the synthesis comprehensive scientific nature consideration to design each link . In brief , is suitable , the security , the economy , easy to operate is this design principle . Design the reasonable feasible construction structure plan is the scene construction important basis .
