“…There are 14 trusses along the long side and 6 trusses along the short side and each corner consists of 4 trusses which means the model has 54 trusses or 53 bays in total. For Optus Stadium, the truss has a total length of 35 m, a maximum depth of 3 m, and a maximum width between bottom chords of 2.4 m [39][40][41]. The height from the top chord to the bottom of the truss is 6 m. The shape of the roof structure is a circle.…”

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 structures considering the Lakhwiya stadium the Optus Stadium and the CommBank Stadium as experimental cases. Using the finite element analysis (FEA) software Strand7, the cases will be modelled and analysed. Varying load cases and combinations such as ultimate strength (ULS) and serviceability limit states (SLS) based on the Australian Standard AS1170.0:2002 will be calculated and subsequently applied. Linear static analysis will then be undertaken where critical members will be identified within the model. Based on this, preliminary member sizing and design feasibility checks will be conducted in order to ensure structural stability and compliance to the Australian Steel Structure code AS4100:2020. A linear buckling analysis is also conducted based on the selected sizes from the initial stage to determine critical loads. Advanced analysis including non-linear buckling computation is comprehensively managed. Some of the crucial parameters such as maximum displacement, maximum/minimum principal stresses, critical buckling loads, as well as load factors are examined. The main novelty of this study is to determine a clear road map to design stadium roofing systems subjected to a combination of different types of the loading.

The building patrimony of Ukraine includes various examples of metallic structures, especially applied for industrial purposes and in large-span structures. The use of metal structures in construction is due primarily to their mechanical properties. They are frost-resistant and able to withstand temperatures down to -65 degrees as well as they are hard, durable, strong and reliable. They can also be used in areas with high seismic activity. However, as in the case of other types of structures, there is a need to restore or strengthen metal structures due to structural defects, wear of load-bearing elements, as well as to increase the load-bearing capacity. In several situations, strengthening with Fiber Reinforced Polymer composites (FRP) gives better results. The current article deals specifically with this strengthening technique. The main cultural reason to restore the old metallic structures and provide a structural functionality, is based on the need to preserve not only their historical origins but also the scenery value of the places in which they are located. That is why the strengthening should be carried out with the aim of maintaining the original design idea. Due to the long-term operation without timely maintenance and major repair, unique and metal large-span structures require strengthening of the load-bearing structures. It is especially important to choose the most efficient method, both in terms of reliability and cost effectiveness. This can lead to the long term interruption of the structure operation and production process, or the inability to use the adjacent territory due to the reconstruction work. At the same time, it is necessary to preserve not only the structure as a whole, but also the external architectural appearance. Traditional methods of strengthening are effective, but in some cases not effective or not applicable for use. An example is the increase of the load-bearing structures of the buildings, preserving the external appearance of which is the determining factor. In this case, the use of the discussed methods can be justified alternative. Disadvantages of steel panels and rods for strengthening are possible corrosion, considerable weight, need for high labor content of the work, and consequently the high cost of labor required to perform the work that need large area. Nowadays, one of the most dynamic types of large-span structures in architectural and structural view are suspension roofs. The aim of the research is the evaluation of the bearing capacity of the suspended rigid threads strengthened with CFRP (carbon fiber reinforced polymer) laminates and provision the general recommendations to implement reconstruction and strengthening with this type of material. Therefore it was considered variant of strengthening suspended bending-rigid fibers by composite materials. Computations are performed in software ABAQUS, as a result of which the percentage reduction in vertical deformation was 26.6% for bending-rigid fibers strengthened with CFRP laminates. The value of tensile stresses reduced by about 14 %. The obtained results of the study confirm the need for further studies and research.

“…For a long time, people have widely used spatial structures, such as Convention and Exhibition Centers [1] Sports Stadiums [2], Industrial Plants [3], Transportation Hubs [4], Military Industry Barracks [5], Ocean Platforms [6], and Tourist Attractions [4]. Compared with the high strength of their material (usually structural steel), their stability is weaker, and they are sensitive to various structural damages and defects.…”

For a long time, spatial structures have been widely used. However, compared with the high strength of their material, their stability is weak, and especially sensitive to damage and defects. This feature has increased the engineering industry’s high requirements for their stability analysis. As we all know, this problem is more prominent for the reticulated shell structure, which is a classic representative of the spatial structure. However, in the current analysis methods for the stability of reticulated shells, the deterministic analysis method cannot consider the random characteristics of defects. Other random methods, such as the random defect modal method, and many improved methods, require more samples and calculation time. This unfavorable situation makes its engineering application greatly restricted. In addition, the random modal superposition method and derivation method based on Monte Carlo has not fundamentally changed this limitation. In order to fundamentally overcome this traditional shortcoming, this paper comprehensively studies the advantages of the high accuracy of the random defect modal method and the improved method, and at the same time, investigates the speed advantage of the response surface method, and then creates a new stochastic analysis method based on the response surface method. Finally, the analysis results of the calculation examples in this paper prove that it successfully balances and satisfies the dual requirements of accuracy and speed required for calculating the stability of the reticulated shell structure. Moreover, it has universal applicability to different forms of reticulated shells, such as classic 6-point flat domes, traditional reticulated shell structures, and bionic reticulated shell structures, and even other types of spatial structures.
