某商场框架结构设计

摘   要

本设计是对某商场框架结构进行设计，内容包括建筑设计和结构设计两部分，结构形式采用现浇钢筋混凝土框架结构。建筑设计要求既符合美学要求又和所选择场地周围环境相适应的，而且需综合考虑了安全性、经济性及适用性等因素。

结构设计主要包括了结构概念设计和结构设计计算两部分组成，结构概念设计依次进行了体系的合理选择，结构平面布置，楼盖结构设计，基础形式的选择，结构构件尺寸的初步估计。结构设计计算首先应用结构分析软件PKPM 建立三维有限元模型进行结构分析，确定了结构概念设计的合理性。然后选取一层楼盖结构进行楼板和次梁的设计计算，以及选取一榀框架，对其在竖向荷载、地震作用、风载作用下进行内力分析，内力组合，最后进行截面设计。依据计算数据确定了PKPM建立的三维有限元模型的结构分析结果和配筋结果的合理性；最后进行了楼梯设计计算和地基基础设计，并使用AUTO CAD绘制结构施工图。

Architecture and Structure Design of Market building

Abstract

This project is about the structural design of some Market building, including architecture design and structure design. Architecture design should make the building aesthetically acceptable and adaptable to the particular site chosen. Moreover, many factors such as safety, serviceability, economical and artistic problems should be taken into consideration.

In structural design, firstly, using “PKPM” establish the three-dimensional finite element model to prove the concept design of the structure is reasonable. Secondly, designing the beam-and-slab floor construction, which includes the design of the floor slab and the beam. Then, finishing the structural design of one piece of the frames, which includes : load calculation ;analysis of the internal force under the horizontal load and vertical load ;design of the section of columns and girders, etc. At last, compared with the result of three-dimensional finite element model, design the stairs and piled foundation, and finish construction drawings.
