Ever wonder how mass timber beam-to-column and column-to-column connections hold up when seismic deformation begins to push a structure beyond its expected limits? For engineers working with mass timber, understanding this behavior is central to design decisions, connection detailing, and project performance. Simpson Strong-Tie senior product engineer Alex Mueller and product engineer Giovanni Pereira will examine seismic deformation compatibility for mass timber connections in a webinar on December 17, 2025, at 10:00 a.m. PT. Presented by Simpson Strong-Tie and hosted by STRUCTURE as part of its sponsored webinar series, the session reviews the mechanics, research insights, and engineering considerations that shape connection performance during seismic demand.
