摘 要

本设计主要对结构方案中横向第2 榀框架进行了结构设计。在确定框架平面布置方式之后，首先进行了层间荷载标准值的计算，接着采用分层法计算得出竖向恒荷载和活荷载作用下的结构内力。然后，利用D 值法求出在水平风荷载作用下的结构内力（弯矩、剪力、轴力）。其次，对各种情况下的内力进行了组合， 选取最安全的结果进行框架梁、框架柱截面的配筋计算。然后，对浅基础的结构进行了设计。最后，利用PKPM 和CAD 软 件绘制了框架结构的施工图。

Abstract

The 11th horizontal frame structure is designed in this design. After determining the frame layouts, the standard values of loads acting on the structure are calculated firstly. Then the internal forces of the structure caused by vertical constant load and live load are calculated by stratified sampling method. Then, the structural internal forces (moment, shear force and axial force).due to horizontal wind load is calculated by using a D value method. Secondly, the internal forces under various circumstances are combined. The security results are selected to calculate the reinforcement of frame beams and frame column. Then, the structure of the shallow foundation is designed. Finally, the shop drawing of the frame structure is drawn by PKPM and CAD software.
