Journal Article
Khokhar, A., Chui, Y. H., & Smith, I. (2019). Influence of between-joists bridging elements on static and dynamic response of wood joisted floors. Engineering Structures, 188, 362-368. https://doi.org/10.1016/j.engstruct.2019.03.039

Excessive vertical vibration of lightweight floors caused by walking or similar activities can be annoying to building occupants. Previous studies have shown that the vibrational performance of floors having wood joists is enhanced by installing one...

Floors with repetitive parallel wood joists overlain by wood panel sheathing behave as orthotropic two-way structures since their along-joist stiffness is much higher than across-joist stiffness. Due to this orthotropy, they have a tendency to produc... Read More about Influence of stiffness of between-joists bracing on vibrational serviceability of wood floors..

This paper presents details of the experimental method, and preliminary results from, a series of torsion tests undertaken to evaluate the shear modulus of Sitka spruce (Picea sitchensis) timber. Direct torsion tests were used to determine the variat... Read More about Determining the Shear Modulus of Sitka Spruce from Torsion Tests.

Ribbed-plate Approach to Predict Static and Dynamic Responses of Timber Floor with Between-Joist Bracing
Presentation / Conference Contribution
Khokhar, A., & Chui, Y. (2016, August). Ribbed-plate Approach to Predict Static and Dynamic Responses of Timber Floor with Between-Joist Bracing. Presented at World Conference on Timber Engineering

Installing between-joist bracing can be an economical and effective means of mitigating excessive vibration levels in wood floors associated to human discomfort. Effectiveness of between-joist bracing depends upon its own rigidity that accounts for t...

Determination of shear modulus of wood joists from torsion tests and relationship with modulus of elasticity
Presentation / Conference Contribution
Khokhar, A., & Zhang, J. (2018, August). Determination of shear modulus of wood joists from torsion tests and relationship with modulus of elasticity. Presented at World Conference on Timber Engineering, Seoul, Republic of Korea

This paper presents the work that was undertaken to use torsion tests to evaluate the shear modulus of wood joists. The relationship of the shear modulus with modulus of elasticity, obtained from bending tests, was examined. Testing standard EN408 h...
