IASS : The International Association for Shell and Spatial Structures (IASS) was found in 1959 by Eduardo Torroja. Its goal is to achieve future progress through an interchange of ideas among all those interested in lightweight structural systems such as lattice, tension, membrane, and shell structures. The activities of IASS include publishing the Journal of the IASS four times a year, organizing annual Symposia and occasional Colloquia, etc. There are several technical Working Groups in the Association according to different research areas.

APCS : The APCS originated from the Korean-Japan colloquium on Shell and Spatial Structures which was co-organized by the late Prof. Y. Hangai and Prof. T. J. Kwun and was held at CheJu, Korea in 1984. This was the beginning of APCS, and the 2nd conference was held in August 1987, Japan. In August 1990, the 3rd conference was held in Korea and was named Asian Pacific Conference on Shell and Spatial Structures firstly. The 4th conference was organized by I. I. S., the University of Tokyo, in October 1993, Japan and became a joint conference in cooperation with IASS. The 5th one was held in May 1996 in China. The 6th APCS will be held in Sungkyunkwan university, Seoul Korea, in 2000. It will be designated as a memorial conference dedicated to the late Prof. Yasuhiko Hangai of I.I.S, University of Tokyo, one of the co-organizer of the 1st APCS and a well-known scholar in the field of shell and spatial structures, who passed away on August 9th, 1998. The 6th, 7th and 8th conference was held in Peking China, Taipei Taiwan and Tokyo Japan, 2009, respectively.
