The 2022 Olympic and Paralympic Winter Games will be held in Beijing.  This makes Beijing the first city in the world to host both Summer and Winter Olympic Games. Some new sports buildings, like National Speed Skating Oval, will be built employing spatial structures with innovation. Besides, sports facilities built for 2008 Summer Games, like National Stadium (Birds Nest) and National Aquatic Center (Water Cube) will be refurbished and capitalized on the legacy from 2008. Either old or new, all the construction will integrate long-term benefits of sustainability.

The annual symposium of the International Association for Shell and Spatial Structures（IASS 2022）will be affiliated with 13^th Asian-Pacific Conference on Shell and Spatial Structures (APCS 2022). Special sessions pertinent to issues in Asian-Pacific area will be organized.

The symposium will be held on 19 - 22 September 2022 at Beijing Friendship Hotel, Beijing, China.

 Objectives

The aim of this symposium is to provide an international forum for engineers, architects, builders and other professionals to present and discuss recent advances on new structural forms, analysis methods, design and construction technologies, maintenance and sustainability in spatial structures, as well as any topics related with shell and spatial structure. It is expected that this symposium will promote developments and bring interests for various new types of shell and spatial structures.
