“…The nonlinear geometric characteristics of such a flexible membrane structure should be considered. The result is consistent with the previous researches [22,23]; this finding indicates that the results in the present study are reliable, and the structural model, as well as the wind load time history, can be used for analysis.…”

Lightweight cable–membrane structures can span large distances and undertake aesthetically pleasing shapes. They are widely used for roofs and modern structural canopies and in the aerospace industry for large on-board antenna reflectors that are to be deployed in space. This paper studies a wind-induced vibration under different cable stress relaxation conditions based on the wind load time-history to obtain the dynamic behavior of such a structure. Particularly, the focus is put upon its wind resistance in the event of stress relaxation. This research can provide an important reference for the design of wind resistance, damage assessment, and emergency maintenance for the spoke-wise cable–membrane structure (SCMS).

“…Next to these experimental studies, numerical investigations using CFD have been performed for double curved membrane roof structures. Some pressure distributions are shown for hypars [14] [20] and umbrella-like cones [21] [22]. However, most of the numerical studies focus rather on the dynamics of these structures including fluid structure interaction coupling frameworks [22]- [26] and vibrations analyses [27].…”

The topologies of membrane and shell structures are not covered by existing wind load Standards and wind tunnel testing should be used to obtain representative wind loads for these structures. However, accurate scale-models of these organically shaped and often open thin structures are complex, time-consuming and expensive to build. To stimulate experimental research on wind load distributions over these structures, this paper illustrates a prototyping methodology for double curved thin shell wind tunnel models with integrated pressure sensors. The production process is illustrated for a hyperbolic paraboloid roof structure. The obtained wind load distributions are validated with literature for a flat roof and canopy that is made according to the same methodology and for two hyperbolic paraboloid roofs. Results indicate that, compared to conventional wind tunnel models, these thin shell wind tunnel models yield more realistic wind pressure distributions over very thin canopy structures. Finally, Cp-distributions are shown for the hyperbolic paraboloid canopy with the high corner under attack. The production of glass-fibre reinforced composites in a CNC-milled mould is convenient and accurate and facilitates the production of wind tunnel models to be used for wind load measurements on organically shaped thin canopy structures.

“…Currently, the shape-finding analysis of cable-supported structures in the construction process mostly focuses on conventional planar, folded, circular, elliptical or parallel shapes, and many theories and methods have been proposed, e.g., a dynamic relaxation method by Motro et al [ 17 ], a force-density method by Schek [ 18 ], a nonlinear force method by Luo and Shen [ 19 ], a nonlinear force density method by Koohestani [ 20 ], a nonlinear dynamic finite element method by Ding et al [ 21 ], a double singular value decomposition method without changing the predefined shape by Zhou et al [ 22 ], a catenary equation-based component force balancing method by Jiang et al [ 23 ], and a novel machine learning approach by Du et al [ 24 ]. By solving the noncompatibility problem between cable and beam elements, Nie et al [ 25 ] coupled the cable network and supporting frame to accurately model the real equilibrium state in an optimization model and derived the linear form for the determination of the free node coordinates from systematic equilibrium equations.…”
