The Tianjin Sports Arena forms part of the campus
of the renowned Tianjin University. It serves as a venue for university and national
sports events and has room for approx. 5,000 spectators.The building is 120 meters long, 58 meters wide, and
located in the northeast of the Tianjin University campus. Situated at the
junction between the campus and downtown the new building is an important link
in the urban structure.
The Sports Arena has a distinctive feature in the form
of a translucent sheath made of gold-colored perforated sheet steel panels,
which form a rhombic structure and emphasize the Arena’s dynamic, powerful
shape. Punching tools were made specially to produce the perforations, which,
with their triangular shape, take up the format of the panels. A special effect
adds further emphasis to the spatial depth and the lightness of the metallic
façade, which is mounted some four meters in front of the actual outer wall: an
enlarged likeness of the structure of the translucent perforated sheet steel
façade (comparable to that of a
silhouette) in the form of a black-and-white print was transferred to the outer
wall of the hall. The overlapping of these two levels – the perforated sheet
steel façade and the likeness of it – produces a Moiré effect, which is
heightened further by the observer moving, and when it is dark, when the space
between the façade and the outer wall is artificially lit.
Two spacious foyers open out the Sports Arena in the
campus and a busy junction in the direction of downtown Tianjin. The two
entrance halls each penetrate the corner of the outer skin and provide access
to the building via the narrow sides. The large expanses of glass in the foyer
extend almost the entire height of the building (24 meters) and create an
entrance that is bright and flooded with light. On the longitudinal sides the
glass facades mimic the inclination of the spectator stands. This way the
geometry of the hall’s interior and the rising spectator stands is also
discernible in the design of the façade.
Furthermore, the sloping roofs of the entrance halls
create an entrance area that expands upwards, and which at its highest point
measures up to 20 meters.
The walls of the entrance halls are bright orange and
form an exciting contrast to the open exposed concrete stairs. These lead from
the foyer directly up to the spectator stands on the inside of the arena, which
have room for some 4,000 spectators. In addition there are 1,000 temporary
places on the longitudinal sides of the court. The rows of spectator seats,
which, being orange and gray, correspond with the color of the foyer, flank a
24 x 44-meter basketball or handball court that conforms to the sports’ rules.
For everyday university purposes the playing area can be divided into two
smaller basketball courts or a maximum of 12 badminton courts. All the
ancillary rooms such as the changing rooms are located in the levels beneath
the stand.
