“…With regard to cable-strut structures, many researches have been done mainly on cable domes or other tensegrity structures, including analysis of feasible initial prestress states (Chen et al, 2012, 2015a, 2015b; Guo and Jiang, 2016; Kim et al, 2007; Pellegrino and Calladine, 1986; Sultan, 2013; Xi et al, 2012; Yuan and Dong, 2003), nonlinear numerical simulations and experimental tests on structural behavior under external load (Gasparini and Gautam, 2002; Guest, 2006; Kebiche et al, 1999), dynamic characteristics calculations (Chen and Feng, 2012), structural optimization (Kawaguchi et al, 1999; Yuan and Dong, 2002), structural failure analysis (Zhu et al, 2013), and new form of structure (Fu, 2005; Yuan et al, 2007, 2008). However, there are still other issues that need to be discussed on conventional WSCSs.…”

Wheel-spoke crossed cable structure is a new type of cable-strut structure. In this article, the tension forming and static performance of wheel-spoke crossed cable structure are experimentally investigated by testing four scale models under full-span and half-span downward uniform load, and the effect of structural parameters including variable prestress level, height difference between inner ring and outer ring, and layer height of inner ring is studied by finite element method as well. The test results indicate that radial cables tensioning scheme is effective for wheel-spoke crossed cable structure to reach initial prestress state, and wheel-spoke crossed cable structure possesses excellent load-carrying capacity and structural stiffness since internal forces and vertical displacements of models vary almost linearly under such load cases. Moreover, the static test results are in good agreement with the finite element analysis results, confirming that the model design, measurement methods, and loading schemes are reasonable. Therefore, the results of this study can provide valuable reference for the design and application of wheel-spoke crossed cable structure.

“…Nowadays, the displacement-based finite element method (FEM) is commonly used in analysis of various structures (Gasparini and Gautam, 2002;Kahla and Kebiche, 2000). For assemblies with infinitesimal mechanisms, the stiffness matrix when using FEM may not have full rank.…”

Cable-strut structures are flexible structures which are very sensitive to their shape variation. Addition of actuators in selected members of cable-strut structures provides an efficient way to control the structural shape, thus enhances the structural performance. Although a large number of research studies have been performed to achieve shape control via linear force method, it has been proved that nonlinear force method is more accurate due to the existence of nonlinearity characters in cable-strut structures. The aim of this article is proposing an approach based on the nonlinear force method to change the shape of cable-strut structures under external load with respect to different control targets. The formulas and calculation procedure of structure’s nonlinear response to external load and length variation of members are established based on nonlinear force method. Then, solving strategy for determining the minimum required number of actuators and testing the feasibility for arrangement plan of actuators is provided for different control targets. Two numerical cases are demonstrated using the proposed approach to obtain the structural behavior before and after the control process. The effectiveness of the algorithm can be verified through numerical results.

“…Such a structural system is essentially discrete. It is not surprising therefore that the finite element method has been successfully used to analyse these structures [1][2][3][4][5][6][7][8][9][10]. Nonetheless, analysing these structures with the finite element method is not a straightforward process.…”
