“…In view of the research on the construction process of building steel structure, Luo et al proposed that the application of BIM technology in the construction of building steel structure can not only control the actual construction cost but also achieve a comprehensive understanding of the overall construction of steel structure, which can fundamentally improve the construction quality of construction projects [3]. Yin et al proposed to reduce the occurrence probability of reverse logistics by analyzing and processing big data, subdividing logistics demand, and combining correlation analysis [4].…”

In order to ensure that the steel structure of the building can meet the requirements of the strength of the building structure and the strict requirements in the fields of earthquake resistance, fire protection, energy saving, and environmental protection in the construction process, a method based on virtual reality supply chain cloud computing collaborative management technology is proposed. This method analyzes the main technology of building steel structure and establishes personalized cloud computing collaborative management technology based on virtual reality supply chain. Based on the analysis of industry characteristics and personalized service characteristics, the virtual reality control mechanism of personalized data mining is proposed by considering the service time cost and user experience quality. Based on cloud computing and VIRTUAL reality GIS, a collaborative management and control system architecture is proposed to optimize user personalized needs and solve the impact of differentiation on the supply chain. Experimental results show that compared with the noncollaborative management scheme, the collaborative management algorithm proposed by this method reduces the interference of personalized differences on supply chain management by 25%. The experimental results show that this method can greatly guarantee the satisfaction of steel structure construction process.

“…In addition, there is a "size effect" in model tests that makes it difficult to realize complex boundary conditions. It is difficult to accurately reflect motion processes and mechanisms using model tests and field investigations because of the limited methods of in situ geological surveys (Chuzel-Marmot et al, 2011;Dai et al, 2017;Luo et al, 2021;Zhang et al, 2017;Liu et al, 2021;Feng et al, 2019).…”

To examine the impact force of the sliding mobility damaging building structures, this study performs inverse modeling of the dynamic response characteristics of building structures under the impact of the Yahuokou landslide. On July 19, 2019, a landslide occurred in Dongshan Town, Zhouqu County, Gansu Province. Nearly 3.92 × 106 m3 of material suddenly lost stability and slid downhill. The sliding body piled up at the foot of the slope and blocked the river. Using the results of a field investigation, the engineering geological background of the Yahuokou landslide is presented in detail. A numerical method is presented to simulate the runout process of the sliding debris and its impact effect on building structures. The smoothed particle hydrodynamics (SPH)-finite element method (FEM) fluid–structure coupling method is implemented to simulate the landslide dynamic disaster process (the impact behavior for buildings). The sliding debris is simulated using the SPH method, and the building structures are simulated using FEM. The velocity variation trends and moving distances of the sliding body in different zones show different evolution characteristics. The landslide debris flow impacts the building, causing part of the structure to be completely destroyed and buried. Part of the broken wall structure moves forward under the impact of the landslide, with the first part of the affected wall unit moving the farthest; this is characterized by “impact collapse.” Studies of detritus flows are helpful to further analyze the disaster mechanisms of landslides, predict their disaster scope, and provide references for landslides with similar geological conditions in China.

“…Failure happens initially at the beam column connection, and then the local damage to the impacted column will eventually lead to structural damage. Luo et al simulated the flow dynamics of a landslide and its impact on reinforced concrete buildings through the explicit time integral analysis of LSDYNA (Luo et al, 2019;Luo et al, 2021), and considered the damage to buildings under three landslide strength levels. Andrewwinner used PLAXIS 3D finite element software to model the original slope and vertical cutting of the slope, analyzed the actual situation of the site prior to its failure, studied the vulnerability of buildings near the slope by using the support vector method, and analyzed the impact of materials on their failure (Andrewwinner et al, 2022).…”

The study of landslide dynamic process and impact damage has important theoretical and practical significance for landslide risk quantitative assessment. Taking Fenghuang Street landslide in Ningqiang County, Shaanxi Province, China as an example, the dynamic process of landslide and its damage to brick-concrete structure buildings are predicted by using discrete element method. Firstly, a three-dimensional numerical landslide model is established by means of the particle flow code system (PFC3D), which is based on landslide investigation, surveying, engineering exploration and geotechnical testing. Secondly, the whole process of landslide deformation, failure, movement and impact damage was simulated, and the velocity, displacement and impact force of the landslide in the motion process were quantitatively studied. Thirdly, the building model (brick-concrete structure) located at the foot of the landslide was constructed by PFC3D and finite element software (Midas/gen), respectively. The characteristics of deformation and displacement of the buildings after the landslide impact are analyzed, and the impact damage of the landslide is predicted. The results show that the rear edge of Fenghuang Street landslide first deforms and fails, and the leading edge is gradually pushed out. After the locking section of the front edge is broken, the landslide begins to slide as a whole, which is a typical push landslide. The main sliding time of the landslide is about 30 s, the maximum average velocity is 3.2 m/s, and the maximum displacement is about 40 m. After the landslide hits the building, the building is displaced in the moving direction of the landslide, and the wall of the building impacted by the landslide is destroyed, resulting in an collapse evident. The relevant research methodologies and findings in this paper can provide a reference for the risk assessment of the same type of landslides, especially the quantitative assessment of the vulnerability for the brick-concrete buildings at risk.
