摘 要

本工程是2015级毕业设计“”设计,共计五层,为多层钢筋混凝土框架结构。本设计中,除第一层层高为5.1米,其他层层高均为3.6米,屋顶3.6米,室内外高差0.45米,建筑物总高度为19.95米。本计算书是针对上述设计的手算书面结果。本设计主要 “建筑设计” “结构设计”两部分。

在“建筑设计”的过程中,主要是确定设计方案,再将几个建筑方案进行对比对照,从而确定更安全、更适用、更经济的最终方案,并确定方案具体的细部建筑构造、做法和材料。

在“结构设计”的过程中,本设计以电算为主,手算为辅。电算过程首先运用结构设计软件PKPM对建筑进行结构建模,计算内力,再根据电算结果用结构绘图软件TSSD绘制结构施工图,此过程在“结构设计”部分的前三十天完成。

“结构设计”的后30天进行手算。手算过程首先确定了第⑦轴线的的受力作为本次的计算任务,根据建筑方案,确定框架所受的及地震荷载等,计算梁、柱、板并以得到各个截面的控制内力,再进行各构件配筋计算。上述内容主要根据EXCEL表格计算,在某些情况也借助过结构力学求解器、MATLAB等软件进行辅助计算和验算。根据所在地区已知的工程地质资料,本结构拟采用阶形独立基础。

并且完成了梯段板、平台板以及、配筋计算的过程,并进行了施工图绘制。

总而言之,经过“襄阳消防执勤楼”设计,我将结构电算和手算的结果进行对比,使我的结构概念更加明确,对框架结构有了更深的认识。在这个过程中,我不仅对本科所学的知识有了系统的回顾,同时熟悉了现行规范、图集,更学会了利用PKPM软件进行电算的基本操作,了解并经历了标准的设计院建筑设计的过程。

Abstract

This project is the 2015 grade graduation design "Xiangyang Fire Service Building" of the School of Civil Engineering and Architecture of Wuhan University of Technology. It has a total of five floors and is a multi-story reinforced concrete frame structure.
In this design, except that the first layer is 5.1 meters high, the other layers are 3.6 meters high, the roof is 3.6 meters, the indoor and outdoor height difference is 0.45 meters, and the total height of the building is 23.55 meters. This calculation book is the written result of the hand calculation for the above design. This design is mainly divided into two parts: "architectural design" and "structural design".

In the process of "architectural design", it is mainly to determine the design scheme under the guidance of the teacher, and then compare several building schemes from various aspects, so as to determine a safer, more applicable and more economical final scheme. And determine the specific details of the architectural structure, practices and materials.

In the process of "structural design", the design is dominated by computer calculation and supplemented by hand calculation. The computer calculation process first uses the structural design software PKPM to carry on the structure modeling to the building, calculates the internal force, then draws the structure construction drawing with the structure drawing software TSSD according to the computer result, this process is completed in the first 30 days of the "structural design" part.

The manual calculation is carried out 30 days after the "structural design". In the process of manual calculation, the force acting on a transverse frame with the bottom ⑦ axis is determined as the calculation task, and the dead load, live load, wind load and seismic load of the frame are determined according to the building scheme. The beam, column and plate are calculated and the internal forces are combined to obtain the control internal forces of each section, and then the reinforcement of each member is calculated. The above contents are mainly calculated according to the EXCEL table, and in some cases, the structural mechanics solver, MATLAB and other software have been used for auxiliary calculation and checking. According to the engineering geological data of the area, the structure adopts step independent foundation.

In addition, this design also carries on the indoor staircase design in the "structural design", and completes the calculation process of the internal force and reinforcement of the structural members such as the ladder plate, the platform plate and the platform beam, and draws the construction drawing.

In a word, after the design of "Xiangyang Fire Service Building", I compare the results of structural computer calculation and manual calculation, so that my structural concept is clearer and I have a deeper understanding of the frame structure. In this process, I not only systematically reviewed the knowledge learned by undergraduate students, but also became familiar with the current specifications and atlas, and learned the basic operation of computer calculation by using PKPM software. Understand and experience the process of standard design institute architectural design.

Key Word: Design of fire service building, frame structure, architectural design, structural design, component calculation
