Displacement in Load Bearing Straw Bale Walls Due To Concentric Compressive Loading
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 6
Abstract
The objective of this research was to provide structural performance data and information for straw bale home builders, building inspectors and engineers. Structural testing of 2 full-scale straw bale walls was undertaken. The tested walls were instrumented and subjected to compressive vertical loading. The results were interpreted in the light of the expected loads that must be withstood in single storey domestic applications. Two specimens of straw baled walls were tested using two techniques for measuring displacement under a maximum load of 2 ton. Pre-compression improved initial stiffness of the straw bale walls. The displacements recorded ranged between 7- 10 mm. It was concluded that placement of a wooden cap plate on top of the straw bale wall is important to insure uniform transfer of the loads along the whole length of the wall. Also this technique of building would confine the connection between the wire mesh, the straw and the plaster to insure the sandwich panel behavior in the section.
