Within the global architecture, engineering, and construction industry, use of Building Information Modeling (BIM) technology has significantly expanded. However, given unique characteristics road infrastructure, application BIM is still being explored. This article focuses on Yuanchen Expressway, exploring innovative applications in comprehensive management. The project employs advanced technologies, including BIM, Geographic Systems (GIS), Internet Things (IoT), to precisely identify...
This paper introduces a new type of steel-concrete composite pylon that has been applied to Nanjing Fifth Yangtze River Bridge (a three-pylon cable-stayed bridge with main span 600 m). For this pylon, the steel shells are connected concrete through PBL shear connectors and studs, inner outer by angle steels. Numerical analysis full-scale model tests show structure exhibits excellent mechanical properties construction performance. The application BIM technology, research development special...
Automated crack detection is vital for structural maintenance in areas such as construction, roads, and bridges. Accurate allows the timely identification repair of cracks, reducing safety risks extending service life structures. However, traditional methods struggle with fine complex backgrounds, image noise. In recent years, although deep learning techniques excel pixel-level segmentation, challenges like inadequate local feature processing, information loss, class imbalance persist. To...
Ultra High Performance Concrete (UHPC) has gradually become the most promising high-performance material, and achieved good results in field of impact explosion protection engineering. In general, normal reinforced concrete (NC) beams subjected to load are prone local punching shear failure. Although pure UHPC can improve their performance, further application is limited by high cost. order achieve balance between resistance economy, this study puts forward design scheme replacement wrapping...
This paper aims to study the influence of key design parameters (e.g., reinforcement ratio, cover thickness, stud spacing, and thickness ultra-high-performance concrete (UHPC) layer) on longitudinal transverse bending performance, as well cracking load ultimate bearing capacity calculation theory steel–UHPC lightweight composite deck (LWCD) structure. Four tests four plates beams were conducted, respectively. The refined finite element models components with different based ABAQUS...
Abstract Steel-concrete composite pylons are rarely used in long-span cable supported bridges. This paper introduces a new type of steel-concrete pylon, which is applied to cable-stayed bridge with main span 600m. For this the steel shells connected concrete through PBL shear connectors and studs, inner outer by angle steels. Numerical analysis full-scale model tests show that pylon structure exhibits excellent mechanical properties construction performance. On other hand, highly...
