The current structural engineering practical standards are unable to offer an universal structural design standard for long-spanning lightweight stadium roofing structures. As such, the design procedure of a particular stadium roof is not replicable to another. This research aims to present a novel design procedure for lightweight stadium roofing s...

... Cable structures are known for providing long spans and bearing large loads. Examples of such structures include football stadiums with enormous roof lengths, which are notoriously difficult to design [1], as well as cable-stayed or suspension bridges (e.g., the Akashi Kaiko suspension bridge in Japan has a span of 1991 m [2]) and mast structures, in which cables are used as guy lines (the highest mast of 646 m was located in Konstantynow in Poland until 1991). However, the most common types of cable structures are used as high-voltage power lines and rail overhead contact lines. ...
This study addressed the structural health monitoring of civil engineering cable structures, in which single cable tension is the key parameter influencing safe and intended behaviour. Traditional methods for monitoring the tension force in a cable are labour-intensive and require direct interaction with the cable. In contrast, the proposed approach provides a remote and rapid assessment of the tension force in the cables of engineering structures using only the shape of the cable. First, a terrestrial laser scanner was used to acquire a point cloud of the cable geometry from a distance. Catenary theory was subsequently applied to the point cloud data to calculate the theoretical tensile force in the observed cable. When the results were compared with those obtained through conventional direct measurements using a dynamometer, the differences were negligible. The proposed approach was subsequently demonstrated on the actual in-service overhead contact lines of a tram system. The results indicated that the precision of the proposed approach is highly dependent on the accuracy of the data describing the physical properties of the cable (cable linear mass). Thus, the proposed approach was proven to be precise, reliable, and rapid, and directions for future research were discussed accordingly.

The current paper discusses about the work made on the study to develop a highly adaptable and versatile stadium, departing from traditional single-purpose designs, with a focus on maximizing utility. With a substantial gross seating capacity of 61424, the stadium is intended to host various sports competitions and large public gatherings. The planning process relies on Computer-Aided Design (CAD) and Building Information Modelling (BIM) software to ensure precise detailing in structural aspects. Advanced engineering software enhances structural analysis, allowing for comprehensive investigations into dynamic load responses. The design's reliability is ensured through a combination of manual calculations and engineering software outcomes.
