Siniat Structural Engineer, Dr Hamidreza Yazdi, co-authored a research paper published in the prestigious academic journal Thin-Walled Structures.
The research paper entitled “Seismic fragility assessment of non-structural drywall partitions with screw and adhesive fixing through multi-axis cyclic testing” is based on experiments conducted at Swinburne University of Technology in Melbourne in February 2020.
In this study, the state-of-the-art multi-axis substructure testing (MAST) system at Swinburne University of Technology was used. The MAST is capable of simulating complex 6 degrees-of-freedom (6-DOF) boundary forces and deformations.
The focus of the project conducted by Siniat was on vulnerability assessment of two large-scale assemblies of nonstructural drywall partitions and suspended ceiling systems. The assemblies included two types of fixings between plasterboard and metal framing, namely, screw fixing as a common construction method, and adhesive fixing recently investigated for mitigating the creaking noise in multistory buildings under serviceability wind loads.
Damage analyses was performed on these specimens which were subjected to previously defined bidirectional inter-story drift demands and their local and global responses were assessed.
The results of this study were published in a research paper which was also co-authored by Dr Javad Hashemi and Professor Emad Gad from Swinburne University of Technology.
“I think the paper is testimony to the integrity of the advanced unique tests that we conducted at Swinburne,” said Hamidreza. “It was a real team effort and I wish to recognize the assistance of teammates Pourya Pazandeh and former employee Alireza Bataghva for their technical support, and also Richard Glaister and Garry Mccarron assistance with the experiments.”
