摘 要
本设计是公司后勤服务楼设计。根据设计任务书的要求，我所设计的办公楼总建筑面积为4500㎡，共四层，建筑占地面积1092.96m㎡，总高为16.2m，按照建筑高度及层数进行分类，此建筑属多层建筑。办公楼主楼为框架结构，平面柱网采用大跨度。根据设计要求，设防烈度为6度，抗震等级为四级。
整个设计分为两部分：建筑设计、结构设计。
根据设计要求入手，从“灵活使用”的角度出发，绿化与建筑相结合，改善外部购物环境。内部采用大、中、小不同的空间尺寸以及斜线、曲线等不同的要素，构成了富于层次流动感强的浓郁的气氛。结构设计是在建筑物初步设计的基础上确定结构方案，选择合理的结构体系，进行结构布置；并初步估算，确定结构构件尺寸，进行结构计算。本工程采用钢筋混凝土框架承重结构体系,且处于抗震设防区,故结构平面布置采用横向框架承重、内廊式三跨布置,结构简单、规则均匀,传力路线直接、明确,适于手算。结构计算包括荷载计算、侧移验算、内力组合与分析、截面设计、配筋计算、楼梯计算、楼板计算及基础计算，并绘制相关的结构施工图。
在设计过程中，框架在水平地震力作用下，采用底部剪力法计算地震作用。风荷载地震作用下的内力计算采用D值法。竖向荷载作用下的内力计算通过弯矩二次分配法求得荷载组合作用值。整个方案设计基本符合设计和结构要求，具有一定的创造性和合理性。
施工组织设计部分提出了合理的工程施工方案，对施工方法、技术措施及施工进度等提出了规定和说明，对施工中涉及到的施工机具、人员配置进行了合理的调配。
总之，适用、安全、经济、使用方便是本设计的原则，两部分空间合理，连接紧凑，主次分明，使建筑空间的舒适度加以提高。

Abstract
This design is the design and design of the logistics service building of XX Toys Co., Ltd. . According to the design plan requirements, I designed the library building area of 4500 square meters total, a total of four floors, each floor area of 1092.96 square meters, with a total height of 14.40m, in accordance with the classification of building height and number of layers, this architecture is a multi-storey building. Library main building frame, plane column net with 3.3x7.5meters. Library with stacks, directories cashier and retrieval, collection rooms, editing room, sterilization room, reading room, computer space, special laboratory. Four with special laboratory, lecture hall, meeting rooms. According to design requirements, fortification intensity is 6 degrees, seismic rating for the fourth.
According to design requirements, begin with "flexible use" point of view, landscape and architecture combine to improve the external shopping environment. Internal use of large, Structural design is based on the preliminary design of the building to determine the structure plan determine the size of structural elements, structural calculation. The reinforced concrete frame construction with load-bearing structural system, and in the earthquake-proof area, is the framework of structural layout with horizontal load-bearing, five cross-type arrangement within the corridor, simple, uniform rules, the force transmission line direct, clear and suitable for hand calculation. Structural calculations including load calculation, lateral checking, combined with the analysis of internal force, section design, reinforcement computation, stair calculation, calculation and basis in the floor and draw the structure of related drawings.
In the design process, the framework of the horizontal seismic force, the use of seismic base shear method. Wind Load Calculation of Internal Forces under earthquake using D value method. Vertical load calculation of internal forces obtained by Moment Distribution Method combined action of load values. The program design meets the design and structural requirements, with some creativity and rationality.
Part of the construction organization design and the reasonable construction plan, the construction method, technical measures and the progress of works and description of proposed regulations on construction related to the construction equipment, staffing for a reasonable allocation.
In short, application, security, economic, easy to use is the design principle, the two parts of space and reasonable connection compact, prioritize, make architectural space to improve comfort.
