Numerical analysis of large air-supported structure of irregular shape is represented. Air-supported
structures are in civil engineering special category of structures, which require different design approach
and consideration from engineering perspective, compared to conventional structures. Structures, made
from most common used building materials (such as wood, concrete or steel), have known geometry,
but unknown internal forces according to design loads. On the other hand, form and geometrical
boundary conditions, when analysing air-supported membrane structures, must be found in first place,
with use of certain level of pre-stress.
First, form-finding of air-supported structure of irregular shape was presented, using commercial
software Dlubal RFEM. Wind loads were because of geometrical irregularitiy of structure specified with
computational fluid dynamics software Dlubal RWIND Simulation. Based on self-weight, internal
pressure, wind loads and snow loads different load combinations with Dlubal RFEM as a part of
geometrical non-linear analysis were performed, to verify load-bearing capacity of choosen materials
and specify foundation loads on the anchorage axis positions, which could be further used for foundation
design.
Individual phases of design procedure of air-supported structures of irregular shape are showed also
with theoretical explanation of numerical methods, which are crucial for design of air-supported
structures and which are present also in the software's background, to perform computational numerical
calculations.
