某综合楼的结构设计

摘要:本工程建造地点在浙江某城市,建筑层数为六层。结构形式是现浇钢筋混凝土框架结构;基础采用筏板基础;建筑结构安全等级二级,设计使用年限为50年。非抗震;基本风压为0.4KN/㎡。室内设计标高为±0.000,室内;外高差600mm。接着计算竖向荷载(恒载及活荷载)作用下的结构内力,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并完成了平台板,梯段板,平台梁等构件的内力和配筋计算及施工图绘制。最后进行了基础的设计

Abstract:The location of this engineering is in one city , Zhejiang province. The building counts six layers. The construction form is cast-in-situ reinforced concrete frame;the seismic fortification intensity is lower than six degree; the reference wind pressure is 0.4 KN/㎡.The interior elevation is±0.000,and it is 600mm higher than outdoors. After the determination of the internal force under the dead and live loads, the combination of internal force can be made by using the Excel software, whose purpose is to find one or several sets of the most adverse internal force of the wall limbs and the coterminous girders, which will be the basis of protracting the reinforcing drawings of the components. The design of the stairs is also be approached by calculating the internal force and reinforcing such components as landing slab, step board and landing girder whose shop drawings are completed in the end.Finally we designed the foundation.

Keywords: cast-in-situ concrete frame design
