Structural Design > Hall of Nations and Hall of Industries, Pragati Maidan, New Delhi
Hall of Nations and Halls of Industries, Pragati Maidan, New Delhi  1971 - 72

Designed as space frame in reinforced concrete; the first of its kind in India, and perhaps in the world; the 'Hall of Nations' provides an uninterrupted exhibition area of approximately 6,700 sqm in a 82m x 82m x 27m high truncated pyramid supported on eight points.

Each of the four 'Halls of Industries' is similar in design and is 44m x 44 m x 16m high.

Free standing coffered mezzanine floors cantilevering out of cylindrical shafts provide additional exhibition area in each hall.

A special 9 member joint was evolved for precast construction but the builder preferred in-situ construction. The joint was modified to suit the adopted technique. The 'Halls of Nations' is supported on pile foundations tied together with post tensioned plinth beams stressed in stages. The 'Hall of Industries' rest on spread footings tied together with high tensile steel bars. The entire complex was analysed, designed and built in a period of fifteen months.
