摘 要

本次毕业设计的题目是南京三宝科技综合楼。该综合楼采用的结构体系为钢筋混凝土框架结构,基础形式采用桩基承台基础。综合楼一共五层,每层层高为3.6m,无地下室。综合楼总建筑面积约为7020m2,主要平面尺寸为54.6m ×28.8m。本综合楼共有三种不同的功能区:一是办公室,二是会议室,三是展览厅。

本次设计选取其中一榀框架即KJ-7进行手算分析设计。主要的设计步骤为:根据经验公式预估梁、柱和板的截面尺寸,画结构的平面布置图;进行荷载的计算,包括恒荷载和活荷载标准值计算;进行框架荷载计算,包括竖向作用下框架荷载计算(恒载和活载)以及横向作用下框架荷载计算(风荷载和地震作用);进行结构内力计算,根据之前得出的框架荷载计算出各种荷载情况下的内力,并画出相应的内力图;进行结构内力组合,根据内力计算结果进行多种情况下的内力组合;选取合适的内力组合结果进行梁和柱的截面配筋计算;再依次进行楼面和屋面板设计、次梁设计、楼梯设计、基础设计以及最后的手算和电算结果分析对比。

Abstract

The topic of this graduation project is Sanbao science and technology complex building of Nanjing.The structure system of the complex is reinforced concrete frame structure, and the foundation form is pile foundation bearing platform foundation. The complex has five floors, each with a height of 3.6m and no basement. The total building area of the complex is about 7020m2, and the main plane size is 54.6m * 28.8m. There are three different functional areas in this complex: the office, the conference room and the exhibition hall.

In this design, frames No.7,was selected for manual calculation and analysis design.The main design steps are: according to the empirical formula, the section size of beam, column and plate is estimated, and the plane layout of the structure is drawn;Carrying out the load calculation, including constant load and live load standard value calculation;The calculation of frame load is carried out, including the calculation of frame load under vertical action (constant load and live load) and the calculation of frame load under lateral action (wind load and seismic action). Calculate the internal force of the structure, calculate the internal force under various loads according to the frame load obtained before, and draw the corresponding internal force diagram. The internal force combination of the structure is carried out. The cross section reinforcement of beam and column is calculated by selecting the proper result of internal force combination. Then the floor and roof panel design, secondary beam design, stair design, foundation design, and finally hand calculation and electrical calculation results are analyzed and compared.

KEY WORDS: frames, structural design, anti-seismic design
