Abstract
The masonry arch is one of the oldest structural designs used to span openings of considerable length. Although a variety of forms of brick masonry arches have been used for aesthetic reasons throughout the history of architecture, the unique employment of simple geometric forms is conspicuous in Louis Kahn′s buildings. In particular, Kahn has distinctively used overlaid circles cut into the building façade for window openings. The research elaborates on how Kahn juxtaposed circular shapes for the design of window openings in his buildings, particularly in the Indian Institute of Management (1962-74) and National Capital Complex in Bangladesh (1962-83).
