Destruction Feature Extraction of Prefabricated Residential Building Components Based on BIM

Abstract

In order to improve the damage feature extraction effect of prefabricated residential building components and improve the structural stability of prefabricated residential components, this paper applies BIM technology to the structural feature analysis of prefabricated residential components. Moreover, this paper adopts the simple superposition method and combines the first strength theory of material mechanics to derive the formula for calculating the cracking torque of prefabricated residential building components under compound torsion. In addition, based on the variable-angle space truss model, this paper uses a simple superposition method to derive the calculation formula for the ultimate torque of composite torsion of fabricated residential building components and applies it to the BIM fabricated residential model. Finally, this paper constructs an intelligent BIM prefabricated residential building construction damage characteristic monitoring system. Through experimental research, it can be seen that the intelligent BIM prefabricated residential building construction damage feature monitoring system proposed in this paper can monitor the damage characteristics of prefabricated residential building construction and can predict the evolution of subsequent building features.

The Assessment of the Maturity of Informatization in Assembly-Building Projects Utilizing the CMM-CME Methodology, Taking a Project in China as an Illustration

“…At present, information technology is extensively employed throughout the entirety of assembly-building projects, including design, production, construction, and administration. For example, the application of building information modeling (BIM) for component damage monitoring [11], the assessment of implied carbon emissions via the Internet of Things (IOT) [12], the implementation of radio frequency signal technology (RFID) to update real-time construction information [13], the utilization of 3D printing technology to print prefabricated components [14], and the optimization of simulations through virtual reality (VR) technology [15]. Additionally, the researchers integrated various information technologies.…”

Rural building cost research practice based on BIM

“…At the present stage, yard-type independent houses are quite common in new rural construction. The floors of such buildings are basically 1-3 floors, and the building area is 100-400 square meters [1] . Take 2-4 floors as an example, the total cost of yard-type rural buildings is about 200,000 to 800,000 RMB.…”

Calibration Method of Feature Point Layout in Prefabricated Buildings Based on Image Recognition Technology

“…A building assembled by prefabricated components on the construction site is called a prefabricated building [1][2][3][4][5][6]. On September 27, 2016, the State Council issued the Guidelines on Vigorously Developing Prefabricated Buildings by the General Office of the State Council, which clearly defined the key areas for vigorously developing prefabricated buildings and steel structures, the proportion of prefabricated buildings in new buildings in the future, and the key cities for developing them [7][8][9][10][11]. Due to the irregular outer contour of most of the prefabricated buildings, it is more difficult and demanding to calibrate their image layout, compared with other types of buildings [12][13][14][15].…”
