位 置:
结构类型:钢筋混凝土框架结构
层 数:五层
总建筑面积:3326.4m2
本办公楼建筑建筑总高度16.5米,共5层,层高3.3米,采用现浇钢筋混凝土框架结构,抗震等级为二级,抗震设防烈度为8度,整个设计包括建筑设计、结构设计部分和施工组织设计部分。
建筑设计部分,首先根据建筑的使用功能确定建筑的初步布局,包括建筑体形及室内空间布置等,然后结合使用的材料、做法进一步确定具体尺寸和平、立面风格等。具体来说,主要包括总平面设计、建筑平面设计(功能布局及布置思路、房间的布置、卫生间的设计、楼梯布置、柱网布置等)、立面设计、剖面设计(层数层高确定及楼梯设计)、建筑材料设计(屋面做法、楼面做法)、防火设计,并对主要设计规范、尺寸单位、荷载及钢筋混凝土作了附加说明。
结构设计部分,首先根据建筑设计、工艺使用要求、材料供应情况以及场地地质条件等确定结构布置方案,然后选取一榀典型框架进行设计计算。在明确计算简图的前提下,进一步确定框架承受的荷载,包括恒载、屋(楼)面活载和风荷载,在此基础上进行框架内力计算(采用D值法计算风荷载作用下的内力,采用弯矩二次分配法计算竖向荷载作用下的内力)、内力组合、梁、柱和基础等构件的配筋计算以及风荷载作用下的侧移验算。除此之外,还进行了楼梯设计(梯段板设计、平台板设计及平台梁设计)、雨篷的设计与计算等。
施工组织设计:科学的依据分项工程,流水施工的方法,合理安排施工顺序,注意安全措施,力求经济效益。
为进一步验证手算结果的精确度,采用PKPM 2005行业软件进行了电算,比较分析表明手算结果是可靠的。最后用AutoCAD进行绘图。

Building Name: The orthopaedic hospital

Struture System: R.C.frame
Number of Stories: 5 stories
Total floor area:3326.4m2
The present project is a 5-storey orthopaedic hospital with the floor height 3.3m and the total height 16.5m. The five-layer building is adopted the cast-in-place reinforced concrete frame structure, and the seismic fortification intensity is 8 with the anti-seismic level 2. The entire graduation project divides into two parts, that is, the architectural design part , the structural design part and the construction organization design.
In the architectural design part, the general layout is first determined according to the building function, including conformation and indoor spatial setting; then the dimension, plane style and elevation style are chosen considering the engineering materials and constructional details. Make it more specific,it includes the total plane design, architectural graphic design (the function layout and layout thinking, the room arrangement and the design of toilet, stair layout, column, etc), the facade design layout, section design(the number and the height of layers identity and stair design), building materials design (roofing approach, the floor practice) and fire prevention design. In addition, instructions for the main design norms and dimensions, load and reinforced concrete is given.
In the structural design part, the array of structure is first determined according to architectural design, process demand, material supply and geological conditions; then a typical transverse frame is taken to be computed. After the extract of computation sketch, the external loads such as the dead load, living load on the roof (floor) and the wind load are calculated; then the internal force in the structure is obtained through the moment distribution method under vertical loading and the modified knick point method under horizontal loads. In the following, the combination of internal force is performed. On the above basis, the design of structural components such as beams, columns and foundations are respectively carried out, and at the same time the checking computation of the slidesway under wind load is done. In addition, the design of the stair (ladder period of board design, smooth bedplate design and platform beam design), the canopy and other accessory components are also completed.
Construction organization design: the scientific basis of engineering, the construction method of flowing water, reasonable arrangement of construction order, pay attention to safety measures, strive for economic benefits.
To verify the accuracy of above results, numerical tests are performed with the software PKPM 2005, and the comparisons prove that the original results are reliable. Finally, the construction documents are completed using the software AutoCAD 2007.
Keywords: Reinforced concrete frame; Architectural design; Structural design.
