BIM (Building Information Modeling) technology has been widely applied in structural design, serving as an essential tool for building informatization. By constructing 3D digital models, BIM achieves the integration of design, analysis, optimization, and management, significantly improving the efficiency and quality of structural design. The parametric modeling functionality of BIM simplifies adjustments and optimizations of structural schemes. Its visualization features enhance interdisciplinary collaboration and communication. Furthermore, the integration of emerging technologies such as cloud computing and big data with BIM opens new avenues for automation and intelligent structural design. In addition, BIM’s application in the renovation of existing buildings supports the extension of building lifespans and contributes to sustainable development. Given its significant advantages, this paper analyzes the characteristics of BIM technology and delves into its specific applications in structural design. The goal is to provide a reference for advancing BIM technology in structural design practices.

As time goes by, shared bikes have become an essential element in people's life. However, due to the limited number and uneven distribution of shared bikes, it has brought some troubles to people's daily travel. In this paper, we establish an empty vehicle scheduling model with normal distribution and study the empty vehicle scheduling problem of shared bikes. This paper establishes a model based on real life, assumes different scheduling schemes, and compares different assumptions, so as to get better empty vehicle scheduling schemes. In this way, shared bikes will be more conducive to People's Daily travel and bring more convenience to people.

At present, lithium-ion batteries (LIBs) have been vastly applied and are widely being used for portable device, hybrid electric vehicles, and aviation field. Cathode materials, as the most important part in the LIBs, shows a profound prospect and potential. This study mainly focuses on the study of the means of how to improve the electrochemical properties and performance of the NCM cathode materials, examining the characterization of the NCM cathode materials through the characterization techniques. By referring different doping elements on NCM cathode materials, this paper aims to examine the structural properties, electrochemical performance, and stability of these materials under different dopants. Several characterization techniques, inductively coupled plasma (ICP), x-ray photoelectron spectroscope (XPS), Scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive spectroscope (EDS), and x-ray diffraction (XRD) results have clearly displayed a large amount of figure on cathode materials, which help us to gain a better understanding on the characteristic of each cathode materials and help us to do the further calculation and study on cathode materials.

According to the renovation needs of construction projects and the actual situation of the site, it is necessary to closely combine the application of electronic information technology to provide solid technical support for the smooth implementation of the renovation plan, aiming to optimize and improve the performance of the building structure, and effectively prevent possible problems in the transformation process and subsequent applications. In addition, in the process of strengthening the effectiveness of construction engineering transformation and promoting the progress of the construction industry, it is necessary to deeply analyze the changes in the current situation, deeply think about the integration and application strategy of electronic information technology, and ensure that the transformation project can achieve the expected results and realize the full and efficient use of information resources. This measure can not only significantly reduce the potential risks in the transformation of construction projects, ensure the successful completion of the transformation tasks, but also help to adapt to the development of the times, maximize the advantages of electronic information technology, and inject new vitality into the transformation of construction projects.
