本文为枣庄市三合机械有限公司办公楼结构设计计算书本文考虑了建筑设计和抗震等各方面的要求结合多层框架结构的受力性能、变形特点和设计原则确定了一个相对比较合理的结构布置方案首先确定了平面布置图然后根据其他方面选择了框架结构来进行设计。在明确了框架布局后先求出在水平荷载作用下的结构内力弯矩、剪力、轴力再利用弯矩二次分配法进行荷载的弯矩计算接着使用顶点位移法算出自震周期再使用底部剪力法计算水平地震荷载作用

This article is a structural design and calculation report for the office building of Zaozhuang Sanhe Machinery Co., Ltd. The design considers various requirements, such as architectural design and seismic resistance, and determines a relatively reasonable structural layout based on the load-bearing performance, deformation characteristics, and design principles of a multi-story frame structure. Firstly, the floor plan is determined, and then a frame structure is chosen for the design based on other factors.

After the frame layout is finalized, the internal forces (bending moment, shear force, axial force) of the structure under horizontal loads are calculated, and the bending moment calculation is carried out using the second-order distribution method. Then, the self-seismic period is calculated using the vertex displacement method, and the shear force under horizontal seismic loads is calculated using the base shear method. Finally, the most unfavorable set or sets of internal force combinations are found for internal force adjustment.

Keywords: frame structure, load calculation, internal force combination
