Terrestrial Laser Scanners (TLS) provide manifold possibilities in construction sites. In buildings assembled with steel frames, the “as-built” configuration of the structure can be virtualized by means of TLS measurements in the form of digital 3D point cloud data. This paper presents an integration of procedures related to the reproduction of realistic wire representations of steel frames. This integration encompasses the use of terrestrial laser scanning (TLS) measurements and the development of BIM-friendly wire models based on these measurements. These models are intended to be used in subsequent geometrically nonlinear analysis of the frames using similar BIM environments. All measurements are taken on laboratory tests of sway and non-sway stainless steel subjected to vertical and lateral loading. The “as-built” geometrical initial conditions can be used for the development of models embedded within BIM platforms for their subsequent usage in structural verification.

地面激光扫描仪（TLS）在施工现场提供了多种可能性。在装配有钢框架的建筑物中，可以通过TLS测量以数字3D点云数据的形式虚拟化结构的“竣工”配置。本文介绍了与钢框架的真实线表示的再现有关的程序的集成。这种集成包括使用地面激光扫描（TLS）测量以及基于这些测量开发BIM友好型导线模型。这些模型旨在用于使用类似BIM环境的框架的后续几何非线性分析中。所有测量均在摆式和非摆式不锈钢承受垂直和横向载荷的实验室测试中进行。
