TAIWAN
KEELUNG TRANSIT SHED
A
STRUCTURAL system which en- tails the welding together of round steel bars to form a lightweight hut rigid framework was introduced into Taiwan seven years ago by China Rebar Structures Co. Ltd.

The system is low in cost and permits the erection of wide column- free spans.
Since 1960 it has been widely used in Taiwan and other South East Asian countries on such buildings as stadiums, theatres. hangars, gymnasiums, mess halls and temporary housing.
One of the latest developments on which the system has been employed is a large transit shed of five 50 metre spans, built at Keelung Har- bour and completed last year.
The Rebar structure used here. as on other projects, is basically composed of many triangular forms made by welding diagonally short steel round bars on to three or four bars posi- tioned in parallel.
The skeleton-like formation pro- vides a very strong structure with as little material as possible. Because of its light weight it normally requires only simple foundations, while its hol- low form offers resilience against typhoons or earthquakes.
The round steel bars range in size from 8 in. to 1 in, diameter. Shop welded sections the makers now have factories in Taipei and Kao- hsiung are subject to various tests and finishing treatments before erec- tion on site, including phosphatising to make the surface of the bars resis-
tant to corrosion.

recently reclaimed area, necessitating open caissons as the foundation to transmit reaction forces down to the bedrock underneath. Each of the five independent compartments of the shed measures 50 metres by 45 metres and there is a 3 metre wide canopy, six metres above ground, on all four sides of the building. The floor has a cross slope of 1/50 to provide a railway loading platform.
