Funnel-based bridge modification
The Funnel Concept emphasizes enhancing bridge openings without altering natural stream dynamics. Extend bridge abutments using vegetated keys angled away from the stream until the funnel opening is wider than the meander belt width. Avoid stream modification for bridge alignment and. This paper introduces a new typology of structurally efficient, funnel-shaped shells for light and open architectural applications. Existing. Using the finite element model updating process to obtain the relationship between the structural responses and updating parameters, this paper proposes a method of using the wavelet neural network (WNN) as the surrogate model combined with the wind-driven optimization (WDO) algorithm to update the. 1. 1 The requirements of this Section are recommendatory and are based on best practice and consideration for continuous operation stern first for long periods of time. 708 (17) – Navigation Bridge Visibility and Functions – (Adopted on 6 November 1991) states that 'when.

Qitai Large Span Bridge
The bridge over Hongshui River, situated in Tian'e County in Hechi City of Guangxi, is a two-way four-lane bridge with a total length of 2,488. It is the world's longest steel-reinforced concrete arch bridge in terms of span. [Photo/Xinhua]Spearheaded by Professor Jielian Zheng of Guangxi University and a member of the Chinese Academy of Engineering, the nation is delivering projects that don't just impress on paper but are breaking ground in more ways than one. Unlike previous record breaking arch spans that have always been made of steel, the Longtan Tianhu Bridge is made of concrete. Steel was only used internally as part of a skeleton core. At 11:00 on February 1, 2024, the world's largest span of stiff skeleton concrete arch bridge—Tian'e Longtan Grand Bridge of Guangxi Nandan-Tian'e Expressway was completed and opened to traffic, which is the world's first arch bridge with a span of more than 600 meters.

Sri Lanka Bridge Railing Lights
Sri Lanka Bridge Railing Lighting is a lighting system integrated into Sri Lanka Bridge Railings. These lighting solutions provide a safe environment for pedestrian and vehicle traffic, while increasing the aesthetic appearance of the bridge. It adapts to the architectural design of the bridges. The iconic Nine Arch Bridge in Ella—one of Sri Lanka's most celebrated tourist landmarks—has been illuminated under a heritage monument lighting project jointly executed by the Department of Railways and the Central Cultural Fund. The 104-year-old bridge, constructed during British colonial rule. The bridge is built on an engineering design known as extradosed type, using stay cables to connect the two main pylons with the bridge deck and to share the weight of the loads from the bridge deck. In collaboration with the Central Cultural Fund (CCF), the Railway Department is set to launch a. A groundbreaking project featuring Sri Lanka's inaugural high-tech cable-stayed bridge, constructed with an innovative extradosed design. Spanning over 380 meters with six lanes, it extends.
