1、 I 摘摘 要要 本次毕业设计是一栋病房楼，位于 xxxxx 的人民医院，采用现浇钢筋混凝土框 架结构，占地面积 1200 ，设计使用年限为 50 年，抗震设防烈度为 8 度，耐火等 级为II级,本次毕业设计主要是结构设计。 结构设计是采用的多层混凝土框架结构，根据任务书布置各层平面图，在进行 荷载计算和构件截面估算后，选取一榀框架进行计算，包括框架梁柱截面尺寸的选 取及线刚度的计算、荷载计算、内力计算、内力组合、截面设计及配筋计算。荷载 计算分别进行了恒载、活载、风荷载以及水平地震作用的计算。并且求出了各种荷 载作用下一榀框架的弯矩图、剪力图和轴力图，然后进行了内力组合，选出最不利 截面，进

2、而进行截面设计和配筋计算。 关键词：现浇混凝土框架；结构计算；内力计算；截面设计；配筋计算 II Abstract The graduation project is ward building, which is located the Peoples Hospital of xxx City in xxxxx province.The ward building used cast-in-place reinforced concrete frame structure, which covers an area of 1300 square meters, Design life for

3、 50 years, the intensity of an earthquake resistance of buildings is 8, fire-resistant Grade II.This project is mainly about structural design. The structural design adopts multistory concrete reinforced frame. Finish the plot plan of every layer according to the descriptions of the construction pro

4、ject.After the load calculation and Cross-section Calculation,I select a common framework to calculate, including the calculation of the sectional dimension of beam-column, Line stiffness,load calculation,internal force calculation,combination of internal forces;Design of Cross-section, computation

5、of reinforcement;load calculation including dead load applied calculation and live load applied calculation,wind load calculation and load under the horizontal earthquake action. And find out the bending moment diagram,shearing force diagram, and axial force diagram of the framework with the effect

6、of kinds of loads.Then using the combination of internal force of the structure to find out the critical section and carry out section design and computation of reinforcement.
