PANTEX Lattice Girders

Contents Introduction... 3 Fields of Application... 4 Main Advantages... 4 System Description... 4 System Components... 5 Specifications... 5 Accessories... 6 Further References... 6 Introduction PANTEX Lattice Girders have been developed for special demands in the field of Tunneling. The PANTEX system has been extensively tested and used successfully for numerous tunnel projects throughout the world. PANTEX Lattice Girders ensure an immediate support in the open span area. Contrary to standard solid-web girders, PANTEX Lattice Girders are entirely integrated in the shotcrete lining; porous zones and shotcrete spray shadows are avoided. The load-bearing capacity of PANTEX Lattice Girders has been investigated with various loading tests and by numerical analysis. Flexibility regarding geometry and bearing capacity characterizes this passive support system for underground applications. 3
