摘要：本设计为中恒广场办公大楼结构设计，结构型式为现浇钢筋混凝土框架结构，屋盖及楼盖采用现浇式结构。地上八层，地下一层。高度为30.40米。设计内容主要为结构设计。结构设计过程包括结构方案的确定、结构计算和结构制图。首先进行结构方案的确定，结构布置尽量使得平面形状和立面体形简单、规则，使各部分刚度均匀对称，减少结构产生扭转的可能性。结构方案确定后进行结构计算，学习并运用通用建筑结构设计软件——PKPM建立模型、进行上部结构的整体计算。依据计算结果按制图标准绘制了结构施工图。21474

The Structure Design of Zhongheng Square office building
Abstract：The project which has been designed is the structure design of Zhongheng Square office building. The structure of building is cast-in-place reinforced concrete frame system. Roof and floor cast-in-situ type structure. It has 8 floors on the ground,and 1 floor under the ground.Its height is 30.40 meters. The design mainly includes the structure design. The structural design process mainly concludes three steps: choosing the structural program, structural calculation and structure drawing. First, a suitable program was established. The structural arrangement should make the plane shape and bodily form simple and regulate. So, the stiffness of each part will be uniform and symmetry. In this way, the possibility of distortion will be reduced. Structural calculation involves the following contents: framework, slab, foundation and stairs. One frame was chosen to compute. Then structural design software—PKPM was used to calculate the structure on the ground. The structural drawings were drawn according to the calculated results.
