Full Session with Abstracts
WIth recent analytical and experimental investigation on cross laminated timber rocking wall systems, the knowledge on the design and performance of this innovative system has grow subsetentially. It has been proven through full-scale testing that such a system will have very resilient structural performance when combined with a mass-timber frame gravity system. However, there has not been any standard design method that can be used by design engineers for low to mid-rise buildings using this system. This presentation will discuss an on-going effort supported by US FOrest Service to develop a pre-standard package (i.e. design code provisions to be voted on through a balloting process) for mass timber post-tensioned wall lateral force-resisting systems, which includes 1) Design requirements; 2) Commentary; and 3) Design examples. The project team consists of design practitioners and architects, as well as academic researchers. This pre-standard package in the format ready to be balloted for potential inclusion in consensus codes such as the AWC Special Design Provisions for Wind and Seismic.
