安徽省萧县某中学2#教学楼设计

摘 要

本工程为安徽省萧县某中学教学楼设计，采用的是现浇钢筋混凝土框架结构，主体五层，本地区抗震设防烈度为6度，场地类别为II类场地。

本设计第一步就是进行建筑设计，主要包括对建筑平面布置方案的研究及对构成建筑空间的具体布置的确定，通过对建筑平面的使用功能分析，进行建筑物使用部分、交通联系部分的平面组合设计，进而对建筑体型布局和立面、剖面、屋顶排水进行设计。第二步，便是根据建筑平面布置的结构体系，依据规范规定对建筑结构构件进行初步估算，确定计算简图，计算线刚度，统计荷载，计算重力荷载代表值等数据，从而验算地震作用对房屋所产生的层间位移。再根据竖向荷载计算梁和柱内力再进行组合，从组合表中选出不利组合对梁和柱截面进行设计验算。最后就是对楼梯的设计和计算及对板进行设计。设计完成后用pkpm软件进行验算，验证误差是否在可允许范围内，进行修订，从而最终确定设计结果。

通过毕业设计，使我们进一步巩固和温习了专业基础知识，掌握了设计的基本思路和方法，熟悉了计算机软件的操作，为我们将来走上工作岗位奠定了坚实的基础。

The Design Middle School In Anhui Xiaoxian

Abstract

This project is the design of a middle school in Anhui Xiaoxian, cast-in-place reinforced concrete frame structure, the main five-story, seismic intensity is 6 degrees in the region, site classification to Class II space.

The design of the first step is to carry out building design, including the building layout program and the determination of the specific arrangement constitutes architectural space through the use of the building plan, part of the surface transportation links portfolio design, and then mix and size of the building facade, thereby Body building layout and elevation, section, roof drainage design. Second step, according to the structural system of the building layout, based on the specification of building structural members to preliminary estimates, the determine the calculated thumbs, linear stiffness calculations, statistical load, calculate the gravity load representative value data, thus checking the earthquake housing interlayer displacement. , Based on the vertical load beam and column internal forces then be combined, from to selected adverse combination of beam and column section check combination table. The final step is the design and calculation of the stairs and board design. Checking PKPM software design is complete and to verify whether the error in the allowable range, be amended so as to analyze the design results.

Graduate design, we further consolidate and review the professional knowledge, and to master the basic ideas and methods of design, familiar with the operation of computer software, and laid a solid foundation for our future work
