TruncatedX outperforms conventional designs when subjected to earthquake forces and motions.  Reduced congestion and streamlined geometry lead to solutions that can be built correctly – every time.
 
“TruncatedX is capable of providing cyclic inelastic force-deformation behavior that is equivalent to, and perhaps superior to, that obtainable by conventionally reinforced coupling beams.”
