摘要: A system determines average values for bending stiffness and shear rigidity of a shear band coupon. The system includes: application of multiple, different loads to a midpoint of a first span length of the shear band coupon; determining the deflection of the first span length at each of the multiple loads; application of the same multiple, different loads to a midpoint of a second longer span length of the shear band coupon; determining the deflection of the second span length at each of the multiple loads; determining the bending stiffness at each multiple load from the deflection of the first and second span lengths at each multiple load; averaging the bending stiffnesses at each load to determine an average overall bending stiffness of the shear band coupon; determining the shear rigidity at each multiple load from the deflection of the first and second span lengths at each multiple load; and averaging the shear rigidities at each load to determine an average overall shear rigidity of the shear band coupon.
