Building Information

Purpose This study aims to analyze the dynamic monitoring of deformation damage of steel structure buildings in long-term use. Although the steel structure building has the advantage of high structural strength, it will be deformed after being affected by factors such as corrosion and impact during long-term use, and which will affect building safety, especially the public building facilities. The dynamic monitoring of its security is an indispensable means. Design/methodology/approach This paper briefly introduced the principle of building information modeling (BIM)-based steel structure building information monitoring and the dynamic information monitoring system based on this principle. Then the monitoring system was used to analyze an operational steel structure suspension bridge in Xinxiang City, Henan Province, China, and compared it with the monitoring system based on back propagation (BP) neural network. Findings The results showed that the fitting degree of the dynamic deformation displacement data processed by BIM-based monitoring system was higher than that processed by BP-based monitoring system. Based on the comprehensive comparison of the dynamic data of all monitoring points, the BIM-based monitoring system had higher accuracy of deformation displacement monitoring and reliability of structural safety evaluation. Originality/value In summary, the BIM-based steel structure building monitoring system can effectively monitor the dynamic information of steel structure information.

Building Information

The construction industry is a kind of multi-project engineering. The management in the construction process is an important factor in ensuring construction quality. This paper briefly introduced the relevant content of building information modeling (BIM) and the application of BIM combined with the genetic algorithm in optimizing the processing scheme in the cutting process of steel structure buildings, and took a grid-shaped steel shed in Zhengzhou, Henan, as an example to compare the traditional and BIM optimized schemes. The results showed that the BIM-optimized scheme could make better use of raw materials with different specifications and the optimization scheme had higher economic benefits because of higher utilization rate, fewer processing personnel, and fewer working hours

Arnold Engineering Development Center (AEDC) has designed and built a high-speed data acquisition and processing system for real-time online dynamic data monitoring and analysis. The Computer Assisted Dynamic Data Monitoring and Analysis System (CADDMAS) provides 24 channels at high frequency and another 24 channels at low frequency for online real-time aeromechanical, vibration, and performance analysis of advanced turbo-engines and other systems. The system is primarily built around two different parallel processors and several PCs to demonstrate hardware independence and architecture scalability. These processors provide the computational power to display online and in real-time what can take from days to weeks using existing offline techniques. The CADDMAS provides online test direction and immediate hardcopy plots for critical parameters, all the while providing continuous health monitoring through parameter limit checking. Special in-house developed Front End Processors (FEP) sample the dynamic signals, perform anti-aliasing, signal transfer function correction, and bandlimit filtering to improve the accuracy of the time domain signal. A second in-house developed Numeric Processing Element (NPE) performs the FFT, threshold monitoring, and packetizes the data for rapid asynchronous access by the parallel network. Finally, the data are then formatted for display, hardcopy plotting, and cross-channel processing within the parallel network utilizing off-the-shelf hardware. The parallel network is a heterogeneous message-passing parallel pipeline configuration which permits easy scaling of the system. Advanced parallel processing scheduler/controller software has been adapted specifically for CADDMAS to allow quasi-dynamic instantiation of a variety of simultaneous data processing tasks concurrent with display and alarm monitoring functions without gapping the data. Although many applications of CADDMAS exist, this paper describes the features of CADDMAS, the development approach, and the application of CADDMAS for turbine engine aeromechanical testing.

The Impact

Traditional steel connection systems rely on on-site welding and bolting, which are labor intensive and require skilled craft workers. Reducing welding and bolting efforts in structural steel erection presents an opportunity to improve steel structure construction productivity. A series of steel quick connection systems (SQCS) have been introduced in the market in the last few years, either through research prototypes or commercial products. However, their real benefits need to be confirmed and quantified at actual construction sites. Hence, the main goal of this study was to evaluate the impact of steel quick connection systems on construction productivity and cost. To accomplish this goal, the authors performed analyses of data from nine SQCS projects and conducted two case studies. The authors also utilized a building information modeling based simulation to compare the schedule impact of SQCS and conventional structural steel connections systems. This paper describes the details of this study and its findings.

The Cost

Integrating the knowledge and experience of fabrication during the design phase can help reduce the cost and duration of steel construction projects. Building Information Modeling (BIM) are technologies and processes that reduce the cost and duration of construction projects by integrating parametric digital models as support of information. These models can contain information about the performance of previous projects and allow a classification by linear regression of design criteria with a high impact on the duration of the fabrication. This paper proposes a quantitative approach that applies linear regressions on previous projects’ BIM models to identify some design rules and production improvement points. A case study applied on 55,444 BIM models of steel joists validates this approach. This case study shows that the camber, the weight of the structure, and its reinforced elements greatly influence the fabrication time of the joists. The approach developed in this article is a practical case where machine learning and BIM models are used rather than interviews with professionals to identify knowledge related to a given steel structure fabrication system.
