“…The analysis of the mechanical properties of long-span steel structures has always been a hot topic in the field of steel structure research. At present, most scholars are committed to the study of the normal use stage of large-span steel structures [10], mainly focusing on the dynamic characteristics of steel structures [11], seismic performance [12][13][14][15], wind resistance [16], fire resistance [17], temperature stress-effects [18], earthquake damage reduction [19], snow resistance [20], damage mode for earthquakes [21], comfort [22], and economy [23], among others.…”

A structure does not reach a stable state during the construction process, and hence its structural reliability is low. In order to ensure the safety of the construction process and final structural quality, it is necessary to analyze the safety and structural mechanical properties of large-span space steel structures during the construction process. Based on the engineering background of the polyline symmetrical large-span steel structure construction process, this research established a finite element model of the large-span steel structure on an ANSYS platform. The correctness of the model was verified by comparing the measured frequency of the large-span steel structure with the frequency calculated in the finite element model. Based on the life-death element method, the internal force and deformation response characteristics of the large-span steel structure in the construction process were analyzed, and the different effects of the on-time completion and step-by-step construction on the performance of the broken-line large-span steel structure were compared and analyzed. The study found that the long-span steel truss structure is more sensitive to the construction process, and the final forming state is greatly affected by the construction process. The construction sequence is different, and the structure process and size and distribution of the final stress and deformation are also different. The analysis result of the construction process is closer to that of the actual project. Therefore, appropriate construction paths should be used in the construction process to reduce the impact of path effects on structural performance. It is recommended to pay more attention to the displacement and stress response of the truss when it encounters similar a symmetrical long-span steel structure truss in-place of the forming construction.

“…Therefore, it is necessary to assess the fatigue behaviour of this type of joint, especially depending on the features that determine its operation (the lever lengths). There are numerous research papers on the behaviour of classic bolted connections [10][11][12][13][14][15][16][17], many of them focused on fatigue. For example, Zampieri et al [18] carried out a review of the fatigue resistance of bolted shear connections, Bartsch et al [19] performed an analysis of the fatigue strength of end plate connections with prestressed bolts, and Liu et al [20] showed a simplified modelling strategy based on continuous damage mechanics for the evaluation of cumulative fatigue damage in metal bolted joints.…”

Among the most commonly used materials in the construction of structures in the last two centuries are iron and steel. Clamp joints are a suitable type of joint when it is necessary to rehabilitate or modify a historical steel structure for new uses, reinforcing or modifying it with new beams, without the need to drill or weld on the original structure. The clamps allow beams to be joined with a flange (such as I-beams) without the need for any prior operation on the beams and allow the manufacture of completely removable and reconfigurable structures. Developing and analysing this type of fully removable and reconfigurable structure is necessary. To date, no studies have been carried out on the fatigue behaviour of steel joints by clamps, especially taking into account their main geometric characteristics, such as the size of the clamp levers. In this work, an analytical model is proposed that allows for the analysis of the number of cycles and the fatigue limit of clamp joints as a function of the size of the clamp levers. In addition, various fatigue tests are performed with different clamp sizes. The experimental results are compared with those obtained with the proposed methodology. Finally, the relationships between the lever length and the fatigue behaviour of the clamp joints have been determined. It is concluded that an increase in the size of the front lever is associated to a decrease in the fatigue limit. On the contrary, if the size of the rear lever is increased, the fatigue limit of the joint increases. In general, according to the obtained results, the resistance of the joint can be reduced to approximately one third when it is subjected to fatigue loads.
