Typical Floor Elevation View Washer Nut Extra vertical members (columns) to allow for support of threaded bar, washer and nut Column Beam Threaded Bar Typical Floor Plan View Nut Washer Threaded Bar Nut and washers will be tightened by hand to secure weights for testing – this will cause the frame to deflect inwards, if not properly braced Column Direction of shaking (to be decided by judges) Recommended locations for extra beams to prevent deflection of frame due to clamping action of weight attachment Figure 4-2: Anchorage of Weights to Structure Undergraduate Seismic Design Competition 19
(a.) Example of insufficient support for threaded bars that prevents the requisite tightening of the nuts, thereby permitting the bars to move relative to the structure during shaking. Vertical columns at the location of threaded bars would have facilitated weight attachment, including tightening of the nuts to prevent rolling and sliding of the bars during shaking. Accelerometer Vertical Columns at Threaded Bar Locations Threaded Bar Weights (2005 Competition) (b.) Example of an ideal support for threaded bars. Vertical columns facilitated weight attachment, and prevented rolling and sliding of the bars during shaking. Photo taken at 2005 competition, which had a different threaded bar weight distribution than 2006. Figure 4-3: Typical Weight Attachment Undergraduate Seismic Design Competition 20
