Determination of shear modulus of wood joists from torsion tests and relationship with modulus of elasticity (2018)
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...

A form finding method for post formed timber grid shell structures. (2014)
Presentation / Conference Contribution
D'Amico, B., Kermani, A., & Zhang, H. (2014, July). A form finding method for post formed timber grid shell structures. Presented at World Conference Timber Engineering

Timber grid shells provide efficient ways of covering large openings with relatively small amount of materials. With three-dimensional CAD software, it is now possible to model a free-form surface and discretize it in smaller straight elements, thus...

Determining the Shear Modulus of Sitka Spruce from Torsion Tests (2008)
Presentation / Conference Contribution
Khokhar, A., Zhang, H., Ridley-Ellis, D., & Moore, J. (2008, June). Determining the Shear Modulus of Sitka Spruce from Torsion Tests. Presented at WCTE2008:10th World Conference on Timber Engineering

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.

Timber Plate Dynamics with Space-Time Finite Element (2006)
Journal Article
Zhang, H., Ridley-Ellis, D., & Hapca, A. I. (2006). Timber Plate Dynamics with Space-Time Finite Element. Timber Engineering,

A new space-time finite element formulation for dynamic analysis of timber plates is presented. The method is based on an unconventional Hamilton variational principle and a special technique in time domain interpolation is employed. For the simple c...
