Organised by eLearning Board and the Chinese NG.
Speaker: Li Yao, National First-class Registered Structural Engineer, Senior Engineer of China Southwest Architectural Design and Research Institute Co., Ltd.
Moderator: Yaojun Ge, Former President of IABSE, Prof. Dr. Civil Eng., Tongji University, China.
Abstract: Dong'An Lake Stadium, situated in Chengdu, China, served as the opening ceremony venue of the 31st World University Games. The stadium boasts the world' s largest glazed glass lighting roof and roof projection canopy, which redefines the functionality of roof structure. The project pioneered the integration of an extra-long, curved, heavy-loaded platform within the lightweight roof system. Facing these challenges, multiple technical innovations were achieved. These include the development of a multi-discipline parametric surface modeling system, the innovation of a novel force-transfer conversion platform structure, the innovation of material and member types that meet high-precision requirements. In addition, extensive analyses and experiments were conducted to ensure a global first prolonged fireworks display with hundreds of ignition points on a huge glass roof. Furthermore, the circular form of the stadium enabled modularity in the design to achieve economies in both cost and carbon. Dong' an Lake Stadium stands today as a testament to engineering excellence, as well as a cherished cultural icon celebrated for its aesthetic and symbolic resonance.
SPANNING AND CONNECTING: KEY TECHNIQUES AND DESIGN CHALLENGES OF JIANGHEHUI LANDSCAPE PEDESTRIAN BRIDGE, CHINA
DATE: 24 October 2025. Time: 14:00 - 15:00 hrs CET.
WB.NG.7.2025. Register (free): Click Here
Organised by eLearning Board and the Chinese NG.
Speaker: Honglei WU, Prof. of Eng., National First-class Registered Structural Engineer, Chartered Structural Engineer (UK), Deputy Chief Engineer of Tongji Architectural Design (Group) Co., Ltd.
Moderator: Dong Xu, Vice President of Chinese NG, Prof. Dr. Civil Eng., Tongji University, China.
Abstract: The Jianghehui Landscape Pedestrian Bridge is a 380-meter Z-shaped hybrid arch structure spanning the Grand Canal. Through optimal load distribution, utilization of high-performance materials, parametric BIM-driven modeling techniques, and an innovative construction sequencing approach, the bridge achieves enhanced structural safety, improved user comfort, and long-term sustainability. The bridge seamlessly integrates urban connectivity, pedestrian comfort, and cultural heritage, serving as a dynamic landmark and eco-friendly urban link.
INNOVATION DESIGN OF DEMOLITION-CONSTRUCTION COLLABORATIVE TECHNOLOGY IN THE ZHENGZHOU RAINBOW BRIDGE, CHINA
DATE: 7 November 2025. Time: 14:00 - 15:00 hrs CET.
WB.NG.8.2025. Register (free): Click Here
Organised byeLearning Board and the Chinese NG.
Speakers: Xiaofei Wang, Senior Engineer of China Railway SIYUAN Survey & Design Group Co.,Ltd.
Moderator: Yingliang Wang, Prof. Eng., Delegate Chinese NG of lABSE, China Railway Eryuan Engineering Group Co. Ltd., China.
Abstract: The Zhengzhou Rainbow Bridge arches across the largest train marshalling station in Asia. The original bridgedge was built in 1994, with spans of (122 + 62 + 62 + 122) meters and a two-way four-lane configuration. However, with the accelerated urbanization of Zhengzhou, the original bridge's functional deficiencies became apparent. The need for transportation development and railway upgrading made the reconstruction urgent. The new bridge features a three-span continuous single-ribbed steel box bridge with spans of (121 + 125 + 121) meters, accommodating eight lanes in two directions and designed for a speed of 60 km/h. The placement of the single arch rib at the center of the bridge deck optimizes the spatial layout and allows construction and maintenance of arch ribs in the middle of deck. By retaining the original style while introducing innovative structural designs and a dynamic, aesthetically pleasing shape. It harmonizes with the surrounding environment, establishing itself as a new landmark in Zhengzhou. The reconstruction was commenced in May 2021, the demolition was completed in June 2022, and the new bridge was completed and opened to traffic in September 2023. The Zhengzhou Rainbow Bridge represents the first instance in China of bridge construction that crosses a marshalling station through in-situ assembly of large girder segments and longitudinal movement using the transformed bridge demolition system. This innovative solution facilitates the rapid construction of long-span arch bridges over existing railways, significantly reducing construction and operational risks for similar projects while delivering substantial social benefits.
