“…According to the definition of vessel collision failure mode of a single pier, for a single pile-column pier system composed of pile groups, caps, and piers, the failure of any part will lead to the failure of the entire pier system, so the entire pier system constitutes a series system, as shown in Figure 5. e limit state function of a single pile-column pier under various performance levels under vessel collision can be expressed as formula (15). e failure of each performance level of the bridge structure system under vessel impact is defined as that any pier reaches the corresponding performance level state, that is, the whole bridge structure system reaches the corresponding performance level state.…”

“…Safi et al [14] described the basic LCC analysis tools and other useful technologies, indicating an integrated LCC implementation scheme. Ma et al [15] proposed that bridge life-cycle design can be summarized as the design of six processes, including service life design, and proposed an overall framework of bridge lifecycle design, including three design stages and six design processes. Lin et al [16], based on the concept of equal durability design and life-cycle design, proposed the method of life-cycle equal durability design, pointed out its core research contents, and studied the basic ideas, theoretical framework, and design process of the design method.…”

As structures crossing waterways, bridges are obstacles to vessels. Vessel-bridge collisions are inevitable. They not only involve the safety of vessel passage but also seriously affect the safe operation of bridges. Vessel-bridge collisions cause not only huge economic losses and casualties but also severe political and environmental losses. Vessel collision safety of existing and new bridges is one of the key technical problems that engineers and bridge managers must solve. Comprehensive consideration of vessel-bridge collision risk loss and structural performance in the design stage to achieve optimal cost over the life cycle is an important aspect of bridge design. Based on the current life-cycle design theory of engineering structures, this paper proposes a theoretical framework for vessel-bridge collision optimization design based on the life cycle, which includes three parts: vessel-bridge collision probability analysis, vessel-bridge collision vulnerability analysis, and vessel-bridge collision hazard. Taking the minimum cost of the bridge structure in the design service life period as the objective function, the optimization design model and design process of vessel-bridge collision based on whole life are established, and the key problems to be solved in each part are expounded.

“…To help bridge engineering adapt to modern developments, two new concepts -Whole-life Design and Building Information Modelling (BIM) -were proposed and are currently the most often used concepts representing new technologies and methods in the construction industry [3,4]. By definition, a bridge's whole-life design is an integrated design idea to help bridges achieve a satisfactory life-cycle performance and reduce project cost reasonably, which requires that the design stage should have an overall consideration about the integrative cost in each stage [3]. The biggest advantage of whole-life design is that all involved project participants and resources could be globally planned and optimized.…”

The bridge infrastructure is critical to both political and economic development and Building Information Modelling (BIM) is now an innovative technology for bridges’ planning, design, construction and operation. However, it is currently difficult to achieve BIM’s practical value in bridge industry due to existing barriers. The focus of this paper is on proposing a new implemented BIM framework for bridge engineering. Particularly, the research project discussed and summarized the barriers which affect effectiveness and collaboration existed in traditional bridge project delivery and proposed a detailed BIM framework based on the traditional workflow to embrace collaboration and interoperation in the whole lifecycle of a bridge. The framework can significantly facilitate integrating BIM tools and practices, and increase the collaboration and productivity throughout the whole process of a bridge.
