When Hanoi, a hot land in Vietnam, welcomes a new round of construction boom, a magnificent building symbolizing the rise of Southeast Asian sports is about to emerge. This is not only the ambition of Vingroup, the largest private enterprise in Vietnam, but also another milestone for Jinggong Steel Structure Group to compete in the overseas high-end market. Recently, with the signing of a contract, Jinggong Steel Structure officially took over the retractable roof project of the world's largest professional football stadium - Vietnam Copper Drum Stadium. It will construct a steel dome with a diameter of 315 meters on this foreign land.

The rise of new landmarks in Southeast Asia

As the core project of Vietnam's "Hanoi Olympic Sports City", the Copper Drum Stadium has attracted much attention since its inception. The investor Vingroup positions it as a Southeast Asian sports portal, designed strictly in accordance with the highest standards of FIFA. The most shocking data is its scale: there are as many as 135000 planned seats. This means that once completed, it will officially surpass the previously dominant North Korean May Day Stadium (114000 seats) and become the world's largest professional football stadium in terms of capacity. This is not just a breakthrough in numbers, but also a golden business card for Vietnam to showcase its national image to the world.

Giant dome cleverly opens and closes

To give this behemoth the ability to 'breathe', the technical difficulty is extremely high. The overall shape of the stadium roof is circular with a diameter of 315 meters, consisting of a stable fixed roof and a flexible retractable roof. Among them, the fixed roof relies on the main load-bearing truss, circumferential truss, and secondary truss to weave a complex spatial force transmission system, supporting the entire sky like the skeleton of a giant. The task undertaken by Jinggong Steel Structure is to achieve precise opening and closing of the roof on this huge circular structure. The project covers every step from complex structural review in the early stage to precise design of mechanical systems in the middle stage, testing the precision of Chinese manufacturing processes.keywords:Southeast Asia engineering information network

Smart brain on duty 24/7

In addition to the visible beauty of its steel structure, this stadium also harbors a clever 'heart'. Jinggong Steel Structure will implant its independently developed intelligent control system into the texture of the venue, and through deep integration of digital twin and Internet of Things technology, give the building perception capabilities. Sensors scattered throughout the venue are like nerve endings, collecting dynamic data 24/7 and conducting real-time structural health monitoring. Once hidden dangers are discovered, the system can immediately perform fault self diagnosis and automatically push warnings, greatly reducing the difficulty and safety risks of venue operation and maintenance in the later stage. This full lifecycle solution makes this super stadium not only hardcore during construction, but also smart enough during use.Editor/Yang Meiling
