“…Com relação à O&M, muitas pesquisas usaram UAV e LiDAR (BARAZZETTI; PREVITALI; SCAIONI, 2020; CAFISO et al, 2021;JANG et al, 2021;JUSTO et al, 2023;BRUMANA;BANFI, 2022) para levantamento de estruturas existentes, porém há a necessidade de expandir os estudos realizados, já que a maioria se limitou, em seu estudo de caso, a pontes e trechos curtos de estradas. Uma outra questão encontrada está relacionada a dificuldade de levantamento de curvas de pontes e estradas (JUSTO et al, 2023). Outro problema é a perda de informações obtidas pelo UAV ou LiDAR e a necessidade de trabalho manual ao transferi-las e transformá-las em modelos BIM (BARAZZETTI; PREVITALI; SCAIONI, 2020).…”

Este estudo tem por objetivo examinar as pesquisas que abordam o uso do BIM para infraestruturas rodoviárias e entender como estão avançando os estudos nesta área e quais são suas direções futuras. Para isso, uma Revisão Sistemática da Literatura é apresentada em que foram levantados 81 artigos através de busca no WoS e no Scopus. Como resultados, pode-se destacar que o uso do BIM aliado a tecnologias como GIS, LiDAR, UAV permite otimizar projetos e facilitam levantamento de estruturas existentes visando melhorias nas fases de construção e manutenção, o que também permite uma melhor gestão de ativos rodoviários. Contudo, como lacunas do conhecimento foram encontradas, pode-se citar que há necessidade de ampliar estudos para (i) superar barreiras relacionadas a modelagem e levantamento de curvas de pontes e rodovias; (ii) avançar em estudos de interoperabilidade e troca de informações entre programas e partes interessadas; (iii) desenvolver trabalhos relacionados as fases de planejamento, requalificação e demolição.

“…Research on the viability of using point clouds as a tool for real-asset generation in 3D for structural maintenance, repair, and health monitoring applications of existing civil engineering structures has been widely explored in the literature [32][33][34][35][36][37]. The study [38] calculated the deformation accuracy of a structure using two point clouds, one with an undeformed shape and the other with a deformed shape.…”

This study investigates the capture of digital data and the development of models for structures with incomplete documentation and plans. LiDAR technology is utilized to obtain the point clouds of a pedestrian bridge structure. Two different point clouds with varying densities, (i) fine (11 collection locations) and (ii) coarse (4 collection locations), collected via terrestrial LiDAR, are analyzed to generate geometry and structural sections. This geometry is compared to the structural plans, which are then converted into numerical models (finite element—FE model) based on the point cloud data. Point cloud-based FE models (based on fine and coarse data) are compared with the structural plan-based FE model. It is observed that the static and dynamic responses are comparable within an acceptable range of a maximum difference of 5.5% for static deformation and an 8.23% frequency difference, with an average difference of less than 5%. Additionally, the dynamic properties of the fine and coarse point cloud FE models are compared with the operational modal analysis data obtained from the bridge. The fine and course point-cloud-based FE models, without model calibration, achieve an average accuracy of 8.76% and 9.94% for natural frequencies and a 0.89 modal assurance criterion value. The research found that the digital data generation yields promising results in this case for a bridge if documentation or plans are unavailable. With recent technologies and approaches such as digital twins, the connection between physical and virtual entities needs to be established by fusing digital models, sensorial information, and other data forms for better infrastructure management. Models such as those investigated and discussed in this paper can assist engineers with structural preservation in conjunction with monitoring data and utilization for digital twins.

“…2d truss structures are an alternative, with W and N-type trusses being common choices. The choice of profile, truss height, and combination with columns considers needs and costs (Justo et al, 2023;Pereiro et al, 2023;Rady et al, 2024;Yang et al, 2024). Suspended structures, with tension rod supports from cable structures, are an option for extra wide spans, as implemented at the Pulogebang Main Terminal.…”

Industrial building structure planning complies with standards and regulations, such as Procedures for Earthquake Resistance Planning, Minimum Loads for Building Design, and Specifications for Structural Steel Buildings. Vertical and lateral loads are fundamental to the structure's load flow process. Industrial buildings handle roof, wind, earthquakes, crane, and wall loads. Structural design must consider these elements, including the choice of lateral force-resisting systems such as X-bracing. In determining building loads, including earthquake and wind loads, various parameters such as wind speed, exposure category, and other factors must be considered by standard requirements such as SNI 1727-2020 and SNI 1726:2019. Selection of site class, wind direction, topographic, and ground surface elevation factors are essential in determining wind loads. This research method focuses on supporting structures consisting of purlins and girts in the context of industrial buildings. Purlins, made from hot or cold rolled steel, generally use C and Z profiles. Girts, made from cold or hot rolled steel, have profile variations such as C, Z, or hollow square sections. The girt structure design process determines dimensions, rod sag, internal requirements, and sag rod capacity.
