This paper presents some unique design features used for a curtain wall proposed for a new federal building to withstand potential external high explosive threats. The building is a large reinforced concrete frame building with precast concrete wall panels and a glass curtain wall. The curtain wall consists of insulated glass units supported by mullions that are attached to pretensioned steel cables spanning from the foundation to the roof. The glazing was designed using the WinGARD computer program, and the cables were analyzed using a single-degree-of-freedom approach. A three-dimensional finite element analysis of the windows and cables using the commercially-available ADINA code provided similar responses.
