某法院办公楼建筑与结构设计
毕业设计说明书(论文)中文摘要
本次毕业设计题目为泰州市某法院办公楼。总建筑面积约为5400㎡,采用框架承重结构,主体结构层数为三层,层高均为3.9m,抗震设防烈度为7度。
本次设计分为建筑与结构设计两部分。本计算书包括了整个设计的计算过程及相关的说明。
其中主要有结构布置、结构选型、一榀框架的完整计算:包括荷载计算、内力计算、内力组合、截面设计及配筋计算。此外,还有柱下基础、楼梯、现浇板等构件的设计。在框架结构计算时,采用底部剪力法计算地震作用,采用弯矩分配法对框架进行分配,在计算过程中对梁的弯矩进行了调幅,对柱的轴力进行了折减。
在手算的基础上,还使用了PK-PM系列结构设计专用软件进行了电算校核,并对手算及电算结果进行了分析比较。

Title: architectural and Structural Design of a office building of court located in the city of Taizhou
Abstract
The title of this graduation project is architectural and Structural Design of a office building of court located in the city of Taizhou .Total construction area is about 54000 sq.m, frame structure, 3 floors.The height of all floor is 3.9m, the design strength of anti-earthquake is 7 degrees.
This design is divided into two parts: architectural design and structure design. This graduation project includes all the calculations of the design process and related elucidations.
Among them, primarily there are the arrangement of structure, the selection of structure type, a complete calculation of one part of the frame (includes the calculation of load and force, combination of forces, design of section and calculation of reinforcement). Besides, there are design of column foundation, stairs, pored concrete slab and concrete awning etc.
In the framework of structural calculations, calculated using shear at the bottom of the earthquake, a moment distribution method of allocation framework, in the calculation of the beam during the course of a moment of AM, on-the axis of a discount.
Finally, I adopt the PK-PM series structure design software to verify the results of manual calculation, and give the comparison of the manual-calculation and computer- calculation.
Keywords architectural design; structural design; frame structure
the calculation of internal force; the calculation of reinforcement
