新增钢平台结构设计及BIM建模
本工程结构极其不规则，设计时需要考虑到主体结构的使用情况来布置。设计中需要表明和考虑到所有构件的布置情况，节点的连接情况以及施工的方便性。根据分析的结果来确定材料的选择和合理的布局。设计完成后，利用Tekla Structure建立三文模型，通过参数化节点设置创建框架节点详图。

Structure Design And BIM Application In QianLong Additional Steel Platform
Abstract: The main stucture includes five eleven-storey office buildings one twenty four-storey commerce square with two basements,which basement 2 is motor vehicle parking lot and civil air defence.This design is an additional steel platform which is located in basement 1 and independent of the main structure.This design is committed to go into service with main structure in short term.
The reason why this sturcture is very irregular is that we should consider the main structure’s working situation.In this design,we should think of and indicate clearly the arrangement,connections and convenient of construction.According to the analysis,choose the suitable material and arrangement.After the step of designing,use Tekla Structure to create the 3D models of this steel platform with parameteric connections,which can provide the detail design drawings.

一. 工程概况
1.工程概况
本次乾隆文化新增钢平台设计位于上海浦东新区金科路，祖冲之路长泰广场，属于原场地上新增结构，面积约为1000m2。这个项目具有一下特点：
该结构为新增结构,梁柱布置灵活但有限制，因为净高要求，凡人行路线和场地处不应布置钢柱，梁高不易大于200mm，不应大于250mm。
结构平台楼板采用压型钢板组合楼板（单向板为主）。
2.荷载计算
2.1 恒荷载
10厚面层抹灰加特殊防滑添加剂 0.01*30=0.3KN/m
90厚C30混凝土 0.09*25=2.25KN/m
YX28-100-800压型钢板 0.01KN/m
