摘 要

本计算书是针对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1#军人公寓楼”所做的书面成果。本宿舍楼为五层钢筋混凝土框架结构。

在“建筑设计部分”中，主要针对设计初期的几个建筑方案从各个方面对他们进行比较，并确定最终的方案，确定其具体的建筑构造，做法和材料。

在结构设计部分中，首先确定第⑨轴的横向框架作为本次手算的任务，并最终选择方案，确定其具体所受的荷载，其中包括恒荷载，活荷载，风荷载，地震作用，计算梁柱板与内力进行组合后得到各截面的控制内力，最后进行各构件的配筋计算

此外，还进行了结构方案中的室内楼梯设计，完成梯段板，平台板，平台梁等构件的内力计算和配筋计算及施工图绘制。根据工程地质资料，结构采用独立基础

结构设计过程中前30天的时间是先用建筑结构设计软件PKPM对整个结构进行计算，然后在后一个月的时间里选一榀具有代表性的框架进行手算，这样既使自己掌握了PKPM软件的基本应用，同时能是自己对本科四年所学的东西有一个很好的回顾。并把手算与电算的结果进行对比，使自己对框架结构的受力有一个更明确的目的。

Abstract

The written achievement which XiangYang city firemen soldier apartment buildings design abstract this account book aims at Wuhan University of Technology civil engineering specialized 2012level of graduation project .The frame structure for the apartment building is five reinforced concrete .

In the part of architectural design, mainly aims at the comparison from each aspect for several building plans in the design initial period, and determine the final building plan, and then determine its specific construction structure, procedure and materials.

In the structural design part, first determined the ninth axle crosswise frame the duty which calculated for this hand, is clear about its computation diagram and each computation parameter; Then according to the building procedure determined its receives the dead load, the live load, the wind load, the earthquake function, after the computation beam column board and the foundation endogenic force carries on the combination to obtain various sections control endogenic force;

Finally carries on various components to match the muscle computation in addition, but also has carried on in the structure plan room the staircase design, has completed component and so on carriage board, even platen, platform Liang inside computations and matches the muscle computation and the construction drawing plan basis engineering geology material, the structure uses the independent foundation in the structural design process.

The part auxiliary carries on the electricity by “PKPM” to calculate, guaranteed the computation achievement the reliability, and achieved together calculated the achievement carries on the contrast analysis the goal. At the same time, it’s a good review for the four years study in college school, and then compared the result between manual and computer calculates to make myself have a much more clear purpose of frame structure.
