土木工程办公楼毕业设计计算书-西北电子商务中心办公楼设计.docx

摘 要 本次设计的题目是西北电子商务中心办公楼设计。本工程为六层框架结构办公楼，共有建筑面积6612.82平方米，建筑高度为25.2米，层高均为3.60米，冻土深度为0.35米，依照设计的使用年限为50年，建筑防火分类为一类，耐火等级为二级。建筑物抗震设防烈度：7度（0.15g）一组,场地类别为Ⅱ类。 设计首先进行建筑设计，确定纵向柱距为7.8m。在建筑设计中首先应确定建筑的平面布置。在平面布置时应考虑建筑总体规划和周边地形的影响。接着应完成立面设计及剖面设计。结构部分包括电算和手算两部分。电算首先使用PKPM进行结构平面布置，然后输入有关地震的各项参数，最后进行结构内力配筋计算。手算时在初步确定梁、柱截面尺寸后，应计算水平地震荷载作用下一榀框架的横向侧移。然后应根据D值法计算地震作用下一榀框架的弯矩和剪力。接下来应该进行竖向荷载作用下的内力计算，确定计算单元，分别计算恒载和活载作用下框架的内力。最后进行内力组合和配筋计算。 关键字：办公楼建筑；框架结构设计；内力计算；构件配筋 ABSTRACT The subject of this design is Northwest?Commerce?Center?office building design. This construction?is?six-storey?frame?building. The floor area of the building is 6612.82?square?meters. The building’s?height is 25.2?meters. Every floor’s height is 3.60 m. It’s seismic fortification intensity is 7 degrees. The depth of the?frozen soil is 0.35m.The building’s design?life is 50 years. Building fire classified is as A class. The fire resistance rating is Ⅱ class. It’s seismic fortification intensity is 7 degrees(0.15g).Land category is Ⅱ class. Architectural design that is the first design is to determine the longitudinal column spacing is 7.8m. In architectural design i should first determine the layout of the building. The impact of the overall planning and construction of the surrounding terrain should be considered when i arrange in a plane. Next elevation design and cross-sectional design should be completed. Structure design include Computer Calculation and hand calculations in two parts. First, I make structural layout by using PKPM in computer calculation. Then i enter the parameters related to the earthquake. And finally I do calculation about Internal Force Reinforcement. In the hand count I should determine the initial beam and column section size. Then i should calculate the lateral sway of the frame under horizontal seismic loads. Next I calculate the moment and shear of the frame in earthquake based on D value method. I calculate the internal forces under the vertical load and determine calculating unit. I
