The IASS is sad to announce the death of IASS Honorary Member Tien T. Lan at age  95 as communicated by Prof. Su-Duo Xue.

Professor Lan founded China Association for Spatial Structures. He devoted his life to the scientific research and engineering practice of spatial structures.  He made a remarkable contribution to the development of China's spatial structures.  He has also played an important role in academic exchanges of spatial structures between China and the IASS.
