There are many ways of covering a surface. This paper describes the solution adopted for a prototype of an archaeological excavation shelter in Bibracte, France. A nexorade or reciprocal frame system covered with fabric has been designed by French architect Paul Andreu and French engineers Bernard Vaudeville and Simon Aubry (RFR first stage and T/E/S/S second stage). The shelter was built in 2008 and is currently in use.

Among the family of space structures is a typology called nexorades or reciprocal frame structures. Nexorades can have various configurations and shapes. This article focuses on a simple configuration to obtain results that are easy to read and communicate. The aim is to get a better understanding of the structural behavior of nexorades to facilitate their design.Two analytical methods are proposed to calculate the bending resistance and the stiffness of a nexorade. The influence of the connections between members on the structural behavior and the robustness is studied. A comparison is made with flat grids.
