In this session, the application of 3D laser scanning in the evaluation of existing structures will be discussed, as well as recent case studies covering a wide range challenging projects where the conventional evaluation methods were not capable of completing the task. The current state of research and development in the field will also be discussed along with further potential applications of 3D imaging techniques for structural assessment and evaluation.
3D Scanning for Building Analysis
John Smits, East Coast Metrology
The presentation will include an overview of various types of 3D scanning devices such as hand held, mobile units, medium range static scanners and laser trackers along with the specific strengths each one brings to documentation of buildings and structural elements. The resulting data sets will be discussed along with their benefits for design and construction detailing. Examples will be shown to illustrate how scanning data can be used for both pre and post construction forensic studies as well as scanning’s usefulness during the construction process to verify correct placement and alignment of integral building parts.
Sensing-Based Structural Technologies
Farshad Mirshafiei, Sensequake
Sensequake sensing technologies and artificial intelligence are revolutionizing traditional structural engineering practices. Their patented sensing-based seismic evaluation methodology is done without the need for structural drawings or finite-element models. The approach is based on real measured ambient vibrations, is non-intrusive and takes only a few hours. The Sensequake array of technologies, from different wireless sensors to patented data-analysis software, allow for a wide range of unique services: * Obtaining the real dynamic properties or the baseline of a structure (frequencies, mode shapes, damping ratios) * Detecting and locating internal structural damages due to natural hazards or aging * Patented sensing-based seismic evaluation of buildings (compatible with FEMA-P58) * Vibration monitoring services with the Sensequake IoT sensors, real-time web-based dashboard and automated reports and alarms * Permanent structural health monitoring combining artificial intelligence and data analysis for the most comprehensive monitoring platform available All of these data-driven services have been used to monitor and analyze critical buildings and infrastructure across the United-States, Canada and Mexico. The process is a turnkey solution for complete management throughout a structure’s life reducing cost and increasing reliability.
