“…The model parameters in Equations ( 10) and (11) are determined by curve fitting the true stress-strain data of the warp and weft specimens, which are obtained by tensile tests at room temperature. However, the coefficients in Equation ( 14) are solved by the anti-inference method to circumvent performing the difficult shear test, although they can also be obtained by curve fitting the shear test data.…”

“…Therefore, accurate modeling is the primary premise of mechanical behavior analysis of membrane structure. Xu et al [ 11 ] used an improved viscoelastic model to analyze the influence of prestressing on the impact properties of PVDF (polyvinylenedifluoride)-coated fabrics. Xu et al [ 12 ] studied the influence of damping characteristics on the dynamic response of the coated film.…”

It is difficult for the existing Burgers model to accurately depict the off-axis cyclic drawing process of woven coatings. In this paper, the mechanical deformation of woven PVC (polyvinyl chloride)-coated film at different temperatures is investigated. One-dimensional (1D) and two-dimensional (2D) constitutive models were established to characterize cyclic deformation processes. The 1D model is an improved Burgers model. The effects of the time dependence of the viscosity coefficient and the ratio of elastic to viscous deformation are considered simultaneously. The accuracy of the 1D model for predicting the cyclic nonlinear deformation at different temperatures and loading rates is improved. The 2D model is a nonlinear orthotropic model using polynomials. On the basis of the single-objective genetic algorithm, the inverse algorithm is used to obtain the shear polynomial coefficients in the tension phase and the shear modulus in the unloading phase, which circumvents performing the difficult shear test. UMAT subroutines of off-axis stretching and off-axis cyclic stretching are written separately. The intelligent inverse algorithm program consists of a single-objective genetic algorithm program, a finite element parametric modelling program, and a UMAT subroutine. The simulation results are compared with the off-axis cyclic tensile test data to validate the effectiveness and accuracy of the proposed 2D model for the analysis of the woven PVC-coated films in the tension–shear coupling state.

“…For the circular tensile membrane, the smaller the radius, the larger the maximum amplitude, velocity, and acceleration and the smaller the natural frequency, reflecting the more significant dynamic response [81]. Xu et al [82] reported that, in the early stages of the vibration, high-frequency vibrations were induced due to the interaction between the incident waves from the impact and the reflected waves from the side cables, as illustrated by the M-shape in the peak displacement region of the displacement time curve in Figure 13. Furthermore, the maximum incident displacement increased with the increase in pretension.…”

Lightweight and flexible membranes offer different façades for buildings (suitability, competitive costs, durability, and other benefits) compared to traditional building materials. Increasing attention is being paid to membrane structures in the civil and industrial sectors. Acquiring response data or environmental characteristics directly from a model or building is the most straightforward approach to analyzing the properties of membrane structures, which also contributes to the development of theoretical studies and simulation methods along with the enactment of specifications. This paper provides a comprehensive overview of membrane structure performance, including mechanical, thermal, and energetic aspects, alongside the deployment and deflation of inflatable types. Furthermore, the devices used to monitor the structural response are summarized. The constitution of the structure is the most critical factor affecting its performance. A proper design would offer enhanced mechanical properties and thermal environments with a reduction in energy consumption. Non-contact measurement technology has the advantage of causing no structural disturbance and is low cost, but it lacks practical application in membrane buildings. The achievements and limitations of previous studies are also discussed. Finally, some potential directions for future work are suggested.

Xu et al [40,41] focused on the impact response of spherical reticulated shell structures and plane cable-membrane structures, respectively, exploring the effects of various factors on dynamic response and failure modes. Rossot et al [42] conducted studies on geodesic domes and composite materials under impact, enhancing the understanding of structural behaviour under different loading conditions.…”

This paper focuses on the response of reticulated shell structures under oblique impact loads, with a departure from the traditional emphasis on vertical impact loads. These structures are typically utilised in large-span spaces such as iconic buildings and large venues. The study begins by establishing a numerical simulation method for reticulated shell structures subjected to oblique impact loads, which is then validated against existing experimental results. Building on this verified method, the research delves into the effects of varying impactor mass, velocity, and initial kinetic energy on the reticulated shell structure under oblique impacts, as well as the influence of different oblique impact angles. The study extensively examines the failure modes of the structure, node displacements in the structure, and variations in member stress under different impactor parameters. It further investigates how these parameters influence the maximum impact bearing capacity, impact duration, energy dissipation capability, and response forms of the structures, analyzing the reasons behind these effects. The findings offer valuable insights for further research and practical engineering design of reticulated shell structures.
