Abstract:
A flexural joint, comprising:a first joint element, said first joint element having a first load bearing surface, the perpendicular to said first load bearing surface defining a first direction; a second joint element, said second joint element having a second load bearing surface, the perpendicular to said second load bearing surface defining a second direction, said second direction being opposite to said first direction; a third joint element; two first flexure strips attached to said second and third elements at second flexure strip attachment surfaces and upper third flexure strip attachment surfaces, respectively, wherein said second and upper third flexure strip attachment surfaces are separated along said second direction, in respective order; and two second flexure strips attached to said third and first elements at lower third and first flexure strip attachment surfaces, respectively, wherein said lower third and first flexure strip attachment surfaces are separated along said second direction, in respective order, whereby said first and second flexures are under tension when said joint is subject to a compressive load.
