摘要镇江市京口区政府办公大楼，总共5层。建筑总高为18.95m，共5层。其中底层层高为4.55m，其余各层层高为3.6m。
建筑部分：根据建筑的地理位置，所有的功能分区等设计依据进行平面布置、立面、剖面等方面的建筑设计，力求建筑物的实用、经济、美观。
结构部分：结构形式为框架结构，所有的梁、柱及板均采用现浇，基础采用柱下独立基础，绘出结构施工图。
本设计中选取一榀主框架以及一层楼板进行截面设计及配筋计算。首先根据框架布局确定各构件尺寸，进行恒载、活载及风荷载的统计。然后再进行竖向荷载作用下的结构内力计算，水平荷载采用D值法进行计算。之后进行内力组合分析，找出最不利的一组内力，进行构件计算。楼板采用弹性理论设计，并进行柱下独立基础的配筋设计。除此之外，还进行了楼梯的设计计算。最后，根据计算结果，按照相应的构造要求，绘制了结构施工图，并写出了相应的设计说明。51200

Abstract Group locates in ZhenJiang Province. It consists of five stories, 18.95m high. The first story is 4.55m high, and the others stories are 3.6m high. In the top story.
Architectural part: According to its geography situation and all requisite functions and others conditions, we carry out architecture about the plane layout, vertical plane and vertical sections, etc. At this time, we try our best to make the building beautiful, economical and useful.
Structural part: The structure form is a frame structure, all of the columns, beams, and slabs are cast-in-site. Foundations are independent foundations under columns, and we finish the drawing of the structural design for the next construction at last.
One lateral frame and slab was selected and calculated.First,depth and width of sections were determined,and dead load ,live load,wind load were determined.Then the internal forces of the structure under vertical load were calculated.The D-method was used for caculating the wind load.After the combination of internal forces,the most unfavorable combination of internal forces was identified.Then the necessary reinforcement in beams and columns was determined.The elastic theory was used for calculating slab.In addition,the single-foundation and combined foundation were designed.The stairway and canopy were also designed.Finally according to the calculated results and detail, blueprints of the structure had been completed.
Key word: Frame structure；Cast-in-site；structural design；internal force
