• Shape-adaptive Climate Loading of Tensile Surface Structures

  Z. Zajac, R. Lang, I. Němec

  membranes2023.

  
  

  Abstract

  This paper deals with climate loading of tensile surface structures. The approaches for the snow load calculation were summarized and a new usage for tensile surface structures based on established procedures has been proposed. The snow load distribution and accumulation was presented in the form of an algorithm implemented in a finite element software. The results of the algorithm for snow load accumulation were verified on simple examples with vertical, inclined and curved surfaces.

• Does the stress-strain behaviour of PTFE-coated glass fibre fabrics depend on the load history?

  J. Uhlemann, N. Stranghöner

  membranes2023.

  
  

  Abstract

  It is known that PTFE-coated glass fibre fabrics show a mechanical saturation behaviour under repetitive monotonous loads [1]. That means that the stress-strain behaviour changes from load cycle to load cycle. This behaviour is convergent so that stiffness values strive towards asymptote values. However, when using these fabrics in membrane structures they are subjected to various natural load histories which lead to biaxial stresses with different stress ratios in different orders. The question arises whether loads of different orders lead to a different material response. If so, stiffness parameters would not be global but would have to be given dependent on the order of loads.

• Enhanced design and modelling productivity with Parametric design

  H. Nawaz

  Abstract

  This paper focuses on the use of modern parametric design and modelling tools to accelerate the challenging and difficult large design projects. The methodology is also suitable in dealing with renovation and/or modification in the existing structures. Two project examples are presented here namely, construction of membrane façade to existing structure of football stadium Metz, France and renovation of the roof of main train station Dresden, Germany. The structures have deformations with the passage of time and the renovation is more complicated as compared to the theoretical form. Parametrization makes the tasks feasible with enhanced productivity, efficiency and accuracy

• Thermal Performance of Membrane Structures Integrated Phase Change Materials

  J. Hu, W. Chen, J. Zhou

  Abstract

  The membrane structures, one of the typical large-span spatial structures, have been widely-used for sports stadiums and transportation hubs. However, the thermal performance of architectural membrane materials is not as good as those of the traditional building materials. The phase change material can absorb and release latent heat by changing its states within a very small range of temperature change, and thus reducing indoor temperature fluctuation and improving thermal comfort. In this paper, we proposed several membrane structural types to improve the thermal performance, including changing the single-layer membrane structure into two-layer, and setting air or phase change materials as the insulation layer in the middle. Temperature field simulations are performed based on COMSOL software to investigate the temperature variation and thermal performance of the membrane structures. The daily maximum temperature on the inner surface decreased by 2.1°C and 8.1°C respectively with air and PCM layer. We also discovered that the thermal insulation performance will be better when the latent heat value is higher and the PCM layer is placed nearer to the outdoor side. The temperature-stress coupling field showed the loss of pre-stress can be reduced by about 50% by adding PCM layer. The research results are believed to be significant for energy-saving and CO2 emission reduction in large public buildings.

• Designing A Large Span Structures Under Seismic Loading – A Case Study

  F. Dansik, M. Sahin, N. Samat

  membranes2023.

  
  

  Abstract

  Structural membranes have become a frequently preferred system type in long span structures such as amphitheatres, stadiums, performance centres, sport halls, with their ability to cover long distances by lighter solutions. The membrane material, which is the main component of the lightweight structures including membranes and has sufficient strength together with stretching, has very low weight of around 1 kg per sqm compared with the conventional load bearing materials. This is very important feature, both aesthetically and economically. Its light weight does not only provide an economical solution, but also allows to have better structural performance under seismic loads. Besides its lightness, another advantage of membrane-covered structures such as the amphitheatre is acoustic performance, which is an important one for the structure to meet serviceability requirements
