摘 要

本次毕业设计的计算任务是完成武汉理工大学土木工程与建筑学院土木工程专业2012级毕业设计“襄阳消防执勤楼设计”项目。襄阳消防执勤楼为一个地上四层的框架结构建筑。

这次任务共分为建筑施工图的设计，结构施工图的设计以及建模，手算四个部分。将要完成下列任务：选定几个建筑方案，然后在安全、经济、合理等方面进行比较之后，确定采用的方案，以及具体构件的材料和做法。根据材料和做法，以及具体的传力路径，确定所受荷载，包括恒荷载，活荷载，风荷载，地震作用，计算梁、柱、板的弯矩、轴力、剪力，并进行内力组合，然后得到各截面的控制内力，最后进行具体的配筋计算。以及楼梯设计，包括梯段板，平台板，平台梁、梯梁等构件，进行内力和配筋的计算，完成施工图绘制。本结构将采用独立基础，所以还要进行基础配筋计算。

这次毕业设计不仅让自己学到了新的知识，包括软件的使用以及在之前的学习中没有注意到的一些细节，也是自己对四年所学专业知识的一个整合。也在最后对手算与电算进行了一个对比，是自己得到提升的一个重要环节。

Abstract

The graduation project is the completion of the calculation of civil engineering and civil engineering and Civil Engineering College of civil engineering,, 2012 graduate design "Xiangyang fire duty building design" project.The Xiangyang fire protection building is a four story frame building.

This task is divided into the design of construction drawings, design of construction drawings and modeling, hand calculation of four parts.Will complete the following tasks:

Select several building programs, and then compare the security, economic, reasonable and so on, to determine the use of the program, as well as the specific components of the material and practices.According to the material and practice, as well as the specific path of force, to determine the load,Including dead load, live load, wind load, earthquake action, calculation of beam, column, plate bending moment, axial force, shear force, and the combination of internal forces,Then get the control of the cross section of the internal force, and finally the concrete reinforcement calculation.And the stair design, including the ladder section board, the platform board, the platform beam, the ladder beam and so on member, carries on the internal force and the reinforcement calculation,The calculation of internal forces and reinforcement, complete the construction drawing.This structure will be based on an independent basis, so it is also the basis of reinforcement calculation.

The graduation project not only to learn the new knowledge, including the use of software and in the previous study did not pay attention to some of the details, but also their own four years of a professional knowledge of the integration.At the end of the final calculation and the calculation of an opponent is a contrast, it is an important part of their own to get promoted.

Key Word: fire duty building； reinforced concrete,；earthquake resistance design,；independent foundation
