Finite-Element Analysis on Compressive Performance of a Novel Glue-Laminated Cornstalk Scrimber

Abstract EN

Novel glue-laminated cornstalk scrimber is a new timber substitute produced by special techniques, without damaging the original fibers in cornstalks.

This novel material outperforms ordinary timber in the resistance to water, damping, insect, and fire and provides a desirable green building material.

However, glue-laminated cornstalk scrimber has not been widely implemented in the building industry, because the application of cornstalk products is limited to decoration panels.

With the aid of the finite-element software Abaqus, this paper simulates the glue-laminated cornstalk scrimber specimens with different slenderness ratios under axial compression and analyzes the compressive performance of such specimens.

The results show that the height of glue-laminated cornstalk scrimber is negatively correlated with the buckling load and nonlinear load under axial compression and positively correlated with the transverse displacement and axial displacements induced by axial compression.

The research results provide a good reference for improving the design and application of glue-laminated cornstalk scrimber.
