1、 本科毕业设计本科毕业设计( (论文论文) ) 题目题目:南宁市委党校相思湖新区罗文新校园学员南宁市委党校相思湖新区罗文新校园学员 宿舍楼宿舍楼 教学单位:教学单位: 工工 程程 技技 术术 系系 专专 业:业: 土土 木木 工工 程程 20132013 年年 4 4 月月 i 摘摘 要要 本结构设计为一幢钢筋混凝土框架结构体系宿舍楼,主体结构为三层。本设计 主要进行建筑设计和结构设计两部分,建筑部分包括平,立,剖,楼梯,钢筋平面 的设计,结构部分主要以一品框架进行结构设计。 再设计中本该工程抗震设防烈度为 8 度,在确定框架结构布局之后,先进行了 重力荷载代表值的计算,接着利用顶点位移法求出
2、自振周期,按底部剪力法计算水 平地震作用下侧移大小,进而利用 D 值法求出在水平荷载作用下结构内力。接着用 弯矩二次分配法计算竖向荷载(恒载、活载)作用下的结构内力并进行内力组合, 找出最不利的一组或几组内力组合。然后进行梁、板、柱截面设计。同时进行了楼 梯的设计,并完成了平台板、梯段板、平台梁等构件的设计。 关键词关键词:框架 内力组合 重力荷载 弯矩分配 风荷载 地震作用 ii Abstract The structure design for a reinforced concrete frame structure system of dormitory building, the m
3、ain structure is divided into three layers. The design of the main architectural design and structural design of two parts, including the construction of the flat, vertical, profile, stairs, design of steel plane, structure part takes a frame structure design. To design the engineering seismic forti
4、fication intensity is 8 degrees, after determining the frame layout, first calculate the representative value of the gravity load, and then obtained from vibration cycle use vertex from the displacement method, according to the bottom shear method to calculate the horizontal earthquake action of sid
5、e shift, then use the D value method to calculate the horizontal loads the internal force of the structure. Then calculate vertical load bending moment two methods of distribution (dead load, live load) under the internal forces and internal force combination, to find one or several sets of the most
6、 unfavorable combination of internal forces. Then section design of beam, plate, column. At the same time the staircase design, and completed the design of platform boards, boards of the ladder, platform and other components of the beam. Keywords : frame internal force combination of gravity load moment distribution of wind load of earthquake action.
