摘 要

本工程为实际应用课题，地点在徐州市，为某研究院实验楼，三跨四层，三层设办公室若干个，四层设置约110 m²大会议室1个，约70 m²小会议室2个，其余为实验室、环咨室、资料室等。要求采用钢筋混凝土多层框架结构。在正常情况下，本工程的合理设计使用年限为50年，建筑结构的安全等级为二级。设防烈度为7度，设计基本地震加速度值为0.10g，设计地震分组为第二组。地基基础设计等级为丙级。

根据建筑设计和结构承重、抗震方面的要求以及场地地质条件，合理地进行结构选型和结构整体布置，确定各种结构构件的尺寸，选取一榀主要横向结构框架进行结构设计计算，用计算结构力学程序对该榀结构框架进行电算与手算结果进行对比分析；完成楼梯设计和基础设计；用PKPM软件对整栋框架结构进行PKPM电算；绘制出相关建筑和结构施工图。

通过本模拟设计，可使学生综合土木工程专业各课程的知识，了解建筑设计方法，熟悉结构设计与分析过程。

关键词：框架结构；钢筋混凝土结构；设计

Abstract

This project for the practical application of subject, location in xuzhou city, for some research lab building, three across four layers, three layers of several set office, four layers about 110 m2 large conference room 1 set, about 70 m2, small conference room 2, the rest for laboratory, ring client room, library, etc. Require the use of multi-layer reinforced concrete frame structure. Under normal circumstances, the reasonable design of this project use fixed number of year for 50 years, the security level of building structure is secondary. Basic seismic fortification intensity of 7 degrees, design the acceleration value of 0.10 g, design earthquake are grouped into the second group. Foundation design level for class c.

According to the architectural design and structure of the bearing, seismic requirements and site geological conditions, the overall layout, structural type selection and structure reasonably determine the size of the various structural components, selecting one common main lateral structure frame structure design calculation, using computational structural mechanics procedures of the common structure of the computer analysis of comparing with the results by hand; Complete the stair design and basic design; On the whole frame structure with PKPM software PKPM computer; Draw relevant construction and structure construction drawing.

Through the simulation design, can make the students' comprehensive civil engineering professional knowledge of each course to understand architectural design method, be familiar with the structure design and analysis process.
