Effect of partition walls on the seismic response of mass-timber buildings with a post-tensioned rocking wall system

• Combining a flexible rocking wall system and the flexibility of timber can result in building with considerable flexibility. This paper investigates how partition detailing affects dynamic properties structural system. determines when it is beneficial to consider nonstructural walls overall resistance. Fixed contribute significantly seismic resistance while deformation-compatible ones offer little The structural-nonstructural interaction effects post-tensioned CLT mass-timber buildings were evaluated parametric study. Representative 2D units 5-story 12-story archetype modeled OpenSees. Moreover, concentrated spring models developed represent effective force-deformation for four different variations detailing, applied densities associated apartment hospitality occupancies. Eigenvalue, pushover, response-history analyses performed on bare structure those variations. Including fixed connection details was found decrease story drifts shears compared frame model by up 50% service earthquake 30% maximum considered earthquake. However, have negligible influence (less than 5%) response.
