Shake table testing program for mass timber and hybrid resilient structures datasets for the NHERI Converging Design project

This experimental dataset was generated during the NHERI Converging Design project, an NSF-funded collaborative research effort including Oregon State University, Colorado State University, Stanford University, and Penn State University. The vision of this project was to create a new design paradigm within structural engineering that employs multi-objective optimization to maximize functional recovery while integrating additional sustainable building design principles. To validate the design methodology a shake-table testing of a full-scale six-story mass timber structure at the NHERI@UCSD outdoor facility whose resultant dataset is now publicly available.

The six-story specimen emerged from a previously tested ten-story shake-table specimen led by the Dr. Shiling Pei and the NHERI TallWood team (See related dataset in Related Work), where the top four stories were deconstructed to leave a six-story specimen for the NHERI Converging Design team (phase 0 - no data collected). At the completion of deconstruction, the six-story structure was subjected to three distinct phases of shake-table testing that include different lateral force-resisting systems (phase 1-3) that are outlined below:

Phase 1: The first phase of testing featured U-shaped flexural plates (UFPs) as energy dissipators bounding post-tensioned mass timber rocking walls to serve as the lateral force-resisting system.

Phase 2: The second phase of testing featured buckling-restrained braces (BRBs) as energy dissipators at the base of post-tensioned mass timber rocking walls to serve as the lateral force-resisting system.

Phase 3: The third phase of testing featured a resilient steel lateral force resisting system consisting of moment frame/concentrically brace frame with yield-link moment and brace connections in exploration of hybrid steel mass timber structural system solutions.

This dataset is divided in the three distinct phases, each with its distinct Model Configuration and Sensor Information. Readme files are provided for users to understand the data organization and file naming conventions.
