Task 3 Plan

Due to the seismically induced deformation of tall CLT buildings, resilience-critical components are expected to be mostly drift sensitive. These components include non-load-bearing walls (e.g. wood or light gage steel stud walls with gypsum board), exterior curtain wall systems, vertical piping systems, and elevators and egress systems.

The goals of this task are three-fold: 1) identify suitable details for connecting the nonstructural systems to the CLT structural system, 2) identify the contribution of nonstructural systems to the stiffness and strength of the structural system (with Task 2), and 3) develop or modify existing fragility models that connect functionality to seismic demands and resilience performance targets.
