Direct answer
Tie, lateral is a defined term in the International Building Code (IBC) 2009, in Masonry. The code's own words are: “Loop of reinforcing bar or wire enclosing longitudinal reinforcement.” No other I-Code in this corpus defines it, so the IBC 2009 definition is the one to work from. The term is used in 4 chapters of this corpus, most often in Wall Construction (IRC 2009), Soils and Foundations (IBC 2009), Definitions (IBC 2009). These pages transcribe the 2009 model text; verify the definition against the edition and amendments your authority having jurisdiction has adopted. Record the jurisdiction, the adopted edition, the application date and any local amendment that rewrites the definition before you use it on a live project, because a term redefined by amendment changes every requirement that depends on it.
