摘要

本毕业设计题目是扬州市某工业园办公楼设计，结构体系为五层钢筋混凝土框架结构，柱网横向尺寸14.6m，纵向尺寸6×7.8m，底层均为3.6m，建筑面积为3416平方米。

本设计计算书内容主要包括：构件尺寸的初步确定、框架的计算简图、荷载计算、框架在水平及竖向荷载作用下的内力分析、内力组合、梁柱截面设计、板设计、楼梯设计及基础设计。其中地震作用采用底部剪力法确定，水平荷载作用下的内力采用D值法计算，竖向荷载作用下的内力采用迭代法计算。内力组合考虑无地震作用效应组合和有地震作用效应组合两种情况。由于此框架属于三级框架，所以没有进行节点抗震设计，但是在梁柱截面设计时采用了“强柱弱梁”的设计原则。楼梯采用板式楼梯。基础采独立基础。

在设计过程中采用电算对手算结果进行校核，及时发现设计中的错误以及与电算不同的部分，找出原因。

 关键词：框架结构，内力组合，截面设计，独立基础。

  Abstract

The theme of this graduation design is a six-story dormitory in Ningbo city，the structure system is a five stories reinforced concrete framework, the transverse dimension of column grid is 14.6m, the longitudinal dimension of column grid is 6×7.8m, the height of first floor is 3.8m, the height of other floor is 3.6m,the total building area is 3416 sq.m.

The content of this design calculation include: defining magnitude of frame members and calculated sketch of frame, counting loads, calculating internal force of section underlying horizontal and vertical loads, combining internal force, designing section of beams and columns and plate and staircase, and design of the foundation. Horizontal earthquake load is calculated by equivalent base shear method, internal force is calculated underlying horizontal loads by D value method，internal force is calculated underlying vertical loads by iterative method. Earthquake is and not is considered in Combination of internal force. For this frame belonging to third class frame, not counting intersection of beams and columns, but this design obeys the design philosophy of “strong column and weak beam”. Staircase is plate-type. The foundation is pile.

Hand computation is checked by computer in the course of counting, aiming to finding
