“…To calculate displacements, C2C distance computation method was used. This method was developed based on the Hausdorff distance [44], which can be defined as a maximum distance of a set to the nearest point in the other set [45]: ℎ1 3 , 3 6 = 9:; < =:> { ( ; , > )}D (2) where: aA -points of set Ap; bB -points of set Bp; d (aA, bB) -Euclidean distance between aA and bB; Fig. 6 shows the basic concept of C2C distance computation method: (a) there are two point cloud data sets (A) = (a1; a2; a3) and (B) = (b1; b2); The algorythm first searches for minimum distance value from each point in (A) to every point in (B); (b) minimum distance from a1 to every point of (B) is a1b1; (c) minimum distance from a2 to every point of (B) is a2b2;…”

Historical structures, buildings, bridges and walls are very sensitive to deformations which can be caused by many factors, such as winds, heavy rains, extreme temperature variations, ground and soil settlements, tectonic loadings and others. The mapping of three-dimensional deformation maps of building provides an opportunity not only to understand the structural changes, but also to detect zones with a potential risk of damage. The high spatial resolution of Terrestrial Laser Scanning technology allows monitoring historical buildings with millimeter accuracy. Two towers of Istanbul Land Walls were surveyed three times with the 5-month time interval. The accurate deviation maps were obtained from Terrestrial Laser Scanner's data by comparing epochs. Between first two campaigns it happened an earthquake with the magnitude of Mw 5.7 with the epicenter of approximately 60 km from the study area. The findings and outputs of this research indicate that earthquake had a great impact on the monitored structures and deformations were found up to 15 mm for the tower I and up to 20 mm for the tower II.

“…After comparing two different scans, the previous results were verified that there were not any displacements. In [2], a group of Gothic buildings in Valencia that have a historical value were monitoring by levelling. As a result, significant displacements were observed in places where structural weaknesses were most expected.…”

“…Currently, TLS play a very important role in a wide range of purposes that can be directly extrapolated to cultural heritage [37], including the follow-up of an intervention [38], defect detection [39], or the reproduction of existing models [40,41]. However, the high cost of these technologies, the need for specialized management and the pre-processing of the information acquired can be considered as challenges and/or disadvantages.…”

Many projects concerning the protection, conservation, restoration, and dissemination of cultural heritage are being carried out around the world due to its growing interest as a driving force of socio-economic development. The existence of reliable, digital three-dimensional (3D) models that allow for the planning and management of these projects in a remote and decentralized way is currently a growing necessity. There are many software tools to perform the modeling and complete three-dimensional documentation of the intervened monuments. However, the Architecture, Engineering and Construction (AEC) sector has adopted the Building Information Modeling (BIM) standard over the last few decades due to the progress that has been made in its qualities and capabilities. The complex modeling of cultural heritage through commercial BIM software leads to the consideration of the concept of Heritage BIM (H-BIM), which pursues the modeling of architectural elements, according to artistic, historical, and constructive typologies. In addition, H-BIM is considered to be an emerging technology that enables us to understand, document, advertize, and virtually reconstruct the built heritage. This article is a review of the existing literature on H-BIM and its effective implementation in the cultural heritage sector, exploring the effectiveness and the usefulness of the different methodologies that were developed to model families of elements of interest.

“…Microdeformation monitoring, as a dynamic and realtime testing technology, can be an extremely important means for engineering disaster prevention and control [18][19][20][21][22]. Especially, in the field of deformation monitoring, Chai et al proposed a deformation monitoring method based on the fiber Bragg grating technique and established the strain transfer relationship between fiber Bragg grating and shaft lining [23][24][25][26].…”

Shaft linings in thick weakly cemented stratum have the disadvantages of large deformation and repeated damage after repair. Considering the typical geologic characteristics and the failure characteristics of shaft linings, we establish a multilayer automatic deformation monitoring system in this paper, and the monitoring system can realize the real-time, continuous, and long-term dynamic monitoring on shaft linings. Based on the concrete strength failure criterion under biaxial compression and the analytical solution for spatially axisymmetric problem of thick-wall cylinders, the damage limit of the shaft lining in Xieqiao coal mine is obtained. Then, we choose three sections as the test area according to the typical damage forms of shaft linings to carry out the monitoring scheme on the auxiliary shaft in Xieqiao coal mine. The monitoring results show that the extreme value of the shaft lining deformation is 2.369 mm. And the shaft lining located in the border between the floor aquifer and the bedrock generates the most severe deformation, which is about 89.4% of the deformation limit. The shaft lining deformation increment fluctuates in certain range, which belongs to elastic deformation. Finally, we inverse the stress state according to the deformation value of the shaft lining, and the obtained additional stress is found to be lower than the ultimate compressive strength. Long-term project practice confirms that the deformation monitoring results can reflect the real stress condition of the shaft lining and that the monitoring system can realize the real-time dynamic evaluation for the status of the shaft lining.
