长春市多层培训中心
摘 要
本工程为长春市多层培训中心工程，采用框架结构，主体为六层，本地区抗震设防烈度为7度，近震，场地类别为II类场地。主导风向为西南，， KN/M。楼﹑屋盖均采用现浇钢筋混凝土结构。
本设计贯彻“实用、安全、经济、美观”的设计原则。按照建筑设计规范，认真考虑影响设计的各项因素。根据结构与建筑的总体与细部的关系。
本设计主要进行了结构方案中横向框架第3轴抗震设计。在确定框架布局之后，先进行了层间荷载代表值的计算,接着利用顶点位移法求出自震周期，进而按底部剪力法计算水平地震荷载作用下大小，进而求出在水平荷载作用下的结构内力（弯矩、剪力、轴力）。接着计算竖向荷载（恒载及活荷载）作用下的结构内力。是找出最不利的一组或几组内力组合。 选取最安全的结果计算配筋并绘图。此外还进行了结构方案中的室内楼梯的设计。完成了平台板，梯段板，平台梁等构件的内力和配筋计算及施工图绘制。对楼板进行了配筋计算，本设计采用桩基础，对基础承台和桩进行了受力和配筋计算。
整个结构在设计过程中，严格遵循相关的专业规范的要求，参考相关资料和有关最新的国家标准规范，对设计的各个环节进行综合全面的科学性考虑。总之，适用、安全、经济、使用方便是本设计的原则。设计合理可行的建筑结构方案是现场施工的重要依据。

Changchun multi-layer training center
Pick to
The engineering training center for changchun multilayer project, adopting frame structure, main body, the region for six layer seismic intensity of 7 degrees, near the earthquake, the categories for class II field. Leading the wind for southwest, basic wind pressure KN/M , basic snow KN/M pressure. Floor, house cover all use cast-in-situ reinforced concrete structure.
This design implementation "the practical, safe, economic, beautiful" design principle. According to the architectural design standard, carefully consider the various factors influence the design. According to the structure and the construction of overall and detail of the relationship.
This design is the main structure scheme horizontal seismic design framework of third axle. In determining the layout of the framework, after the first layer between the value of load representative, then use the vertex displacement method from the shock, and then ask cycle according to the bottom shear method for calculation of horizontal earthquake loads, and find out the size under horizontal loads of structural internal force (moment, shear force and axial force). Then the vertical load calculation (constant load and load) live under the action of internal force structure. Is to identify the most unfavorable a group or groups of internal f
