The Olympic National Sports Complex in Kiev, Ukraine is about to be completed. Flying struts or 'umbrellas' that are being mounted and form an essential part of the open shed prove that the construction undergoes its final stage.
The 'umbrellas' ensure membrane stretching, supply the membrane with wavy structure to avoid accumulation of snow at the same place, produce natural lighting of the field due to transparent dome and finally carry out an architectural function making the dome look unusual. The strut in the picture is totally assembled.
The dome of the strut is covered with a transparent ETFE film.
All 640 struts were assembled in May and June.
