Journal Article
Lashin, M. M. A., Khokhar, A., Alrowais, F., Malibari, A., & Saleh, W. (2021). Using Artificial Intelligence for Optimizing Natural Frequency of Recycled Concrete for Mechanical Machine Foundation. Recycling, 6(3), Article 43. https://doi.org/10.3390/recycling6030043

This paper investigates the mechanical properties of two different types of recycled concrete, which use wood and rubber, relative to those characteristics of pure concrete, in terms of maximum load and natural frequencies. This paper contributes to... Read More about Using Artificial Intelligence for Optimizing Natural Frequency of Recycled Concrete for Mechanical Machine Foundation.

Influence of between-joists bridging elements on static and dynamic response of wood joisted floors (2019)
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...

Determination of shear modulus of wood joists from torsion tests and relationship with modulus of elasticity (2018)
Conference Proceeding
Khokhar, A., & Zhang, J. (2018). Determination of shear modulus of wood joists from torsion tests and relationship with modulus of elasticity.

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...

Ribbed-plate Approach to Predict Static and Dynamic Responses of Timber Floor with Between-Joist Bracing (2016)
Conference Proceeding
Khokhar, A., & Chui, Y. (2016). Ribbed-plate Approach to Predict Static and Dynamic Responses of Timber Floor with Between-Joist Bracing. In CD-ROM Proceedings of the World Conference on Timber Engineering (WCTE 2016)

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...

Shear failure modes of wood under torsional loading (2014)
Conference Proceeding
Khokhar, A., & Zhang, J. (2014). Shear failure modes of wood under torsional loading. In World Conference on Timber Engineering (WCTE 2014) (428-435)

This paper presents details of the experimental investigation that was undertaken to examine the fracture mechanism of wood in shear. Torsion test method was employed to test structural size timber joists until they fractured. The test joists fract... Read More about Shear failure modes of wood under torsional loading.

Influence of stiffness of between-joists bracing on vibrational serviceability of wood floors. (2012)
Conference Proceeding
Khokhar, A., Chui, Y., & Smith, I. (2012). Influence of stiffness of between-joists bracing on vibrational serviceability of wood floors. In P. Quenneville (Ed.), Proceedings of World Conference on Timber Engineering (WCTE 2012) (362-369)

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..
