Prestressing steel stringers reduces bridge weight by 25%
240-ft long 3 span continuous bridge near Des Moines, Iowa contains prestressed steel stringers comprising A36 wide-flange sections with T-1 steel cover plates for prestressing; 25% saving in weight is achieved as compared with non-prestressed continuous steel bridge of comparable length; each beam is prestressed by placing it on platform and jacking to predetermined deflections; welders tack cover plates while beam is deflected.
