E-Defense Blind Analysis Contest 2009

Results of the Contest

Contest Categories

Winner is selected for each of the four categories:Category1 3D Analysis, Steel damper Category2 3D Analysis, Viscous damperCategory3 2D Analysis, Steel damperCategory4 2D Analysis, Viscous damper


Responses to be predicted (each item has four values which consist of the combination of small / big shaking and X / Y direction except for item c. For 2-D analysis, values of Y-direction and strain are to be predicted.)

a. Maximum values of absolute relative displacement from base and absolute acceleration at each floor

b. Maximum values of absolute story shear and story drift angle at each storyc. Maximum strain at a column in 1st story and middle of a beam in 2nd storyd. Maximum and minimum values of damper force in 1st and 4th storye. Maximum and minimum values of damper deformation in 1st and 4th story

Definition of errors: square-root of sum of squares of errors (RMS errors)

: Predicted response: Measured (actual) response

Points for each response: 8pt. for smallest RMS errors, 5pt. for 2nd ,3pt. for 3rd,1pt. for 4th
