Structural inspection is essential to improve the safety and sustainability of infrastructure systems, such as bridges. Therefore, several technologies have been developed to detect defects automatically and accurately. For example, instead of using naked eye for bridge surface defect detection, which is subjective and risky, Light Detection and Ranging can collect high-quality 3D point clouds.This paperpresents the Surface Normal Enhanced PointNet++ (SNEPointNet++),which is a modified version of thewell-knownPointNet++methodapplied to thetask of concrete surface defectdetection. To this end, a point clouddatasetfrom three bridges in Montreal was collected, annotated,and classified into the three classesofcracks, spalls, and no-defects. Based on the comparison between the results(IoU)from the proposed method and similar researchdoneon the same dataset, there areat least 54% and 13% performance improvementsin detecting cracks and spalls,respectively.

A digital twin (DT) can be defined as a multi-physics, multiscale model in which a digital model, such as a building information model (BIM), is updated based on data obtained from a physical system as well as results from probabilistic simulations and models. This study describes the critical steps towards the implementation of DTs to support structural health monitoring (SHM) of mass timber buildings. In particular, the study defines a methodological approach used to integrate as-built geometry of existing buildings, as well as their material properties and sensors, to link SHM parameters into a digital model to assist in assessing a building’s structural performance. A coupled pair of post-tensioned cross-laminated timber (CLT) self-centering shear walls at the George W. Peavy Forest Science Center (“Peavy Hall”) at Oregon State University were used as a case study to test the proposed approach. The BIM of the shear walls was developed using a Scan-to-BIM approach by converting LiDAR point clouds into a BIM. Sensors in the building recorded environmental and structural parameters influencing the long-term performance of the
数字孪生(DT)可以定义为多物理场、多尺度模型，其中数字模型(如建筑信息模型(BIM))基于从物理系统获得的数据以及概率模拟和模型的结果进行更新。本研究描述了实施DTs以支持大型木结构建筑结构健康监测(SHM)的关键步骤。特别是，该研究定义了一种方法方法，用于整合现有建筑物的建成几何形状，以及它们的材料特性和传感器，将SHM参数链接到数字模型中，以协助评估建筑物的结构性能。俄勒冈州立大学George W. Peavy森林科学中心(“Peavy大厅”)的一对后张交叉层压木材(CLT)自定心剪力墙作为案例研究来测试所提出的方法。剪力墙的BIM采用扫描到BIM的方法，将激光雷达点云转换为BIM。建筑物内的传感器记录影响建筑物长期性能的环境和结构参数
