Alternative anchorage concepts were developed using a modified version of the ACI 318-11 procedures for embedded anchor design. Four design concepts were developed for review by IaDOT, including: (1) a four-bolt square anchorage, (2) a four-bolt spread anchorage, (3) a twobolt centered anchorage, and (4) a two-bolt offset anchorage. IaDOT representatives selected the four-bolt spread anchorage and the two-bolt offset anchorage as the preferred designs for evaluation. In addition to these two proposed configurations, IaDOT also requested that the researchers evaluate a third option that had been previously installed on the US-20 bridge near Hardin, IA. The proposed alternative anchorages and the original cast-in-place anchorage for the BR27C combination bridge rail were evaluated through dynamic component testing. The test of the original cast-in-place anchorage was used a baseline for comparison with the alternative designs. Test no. IBP-1 of the original cast-in-place anchorage developed a peak load of 22.9 kips (101.9 kN) at a deflection of 1.5 in. (38 mm). All three of the tested alternative anchorages provided greater load capacity than the original cast-in-place design and were deemed acceptable surrogates. Of the three alternative designs, the two-bolt offset design was deemed the best option. 516 $a Text file in PDF format. 538 $a System requirements: Adobe Acrobat, Adobe Acrobat Reader, or other PDF reading software. 538 $a Mode of access: World Wide Web 513 $a Final Report 650 0 $a Bridges $z Iowa. 650 07 $a Adhesion $2 trt 650 07 $a Anchor bolts $2 trt 650 07 $a Anchorages $2 trt 650 07 $a Anchoring $2 trt 650 07 $a Bridge design $2 trt 650 07 $a Bridge railings $2 trt 650 07 $a Design load $2 trt 650 07 $a Dynamic tests $2 trt 650 07 $a Epoxy coatings $2 trt 650 07 $a Highway safety $2 trt 650 07 $a Impact tests $2 trt 650 07 $a Roadside improvements $2 trt 700 1 $a Reid, John D., $e author. $u Midwest Roadside Safety Facility. 700 1 $a Rosenbaugh, Scott K., $e author. $u Midwest Roadside Safety Facility. 700 1 $a Haase, Austin J., $e author. $u Midwest Roadside Safety Facility. 700 1 $a Faller, Ronald K., $e author. $u Midwest Roadside Safety Facility. 710 2 $a University of Nebraska--Lincoln. $b Midwest Roadside Safety Facility, $b Midwest Roadside Safety Facility, $e performing body. 710 1 $a Iowa. $b Department of Transportation, $e sponsoring body. 856 40 $a Iowa Publications Online $3 Online Access $z Full report $u http://publications.iowa.gov/id/eprint/21115 856 40 $a Midwest Roadside Safety Facility $3 Online Access $z Report PDF $u http://mwrsf.unl.edu/researchhub/files/Report313/TRP-03-325-15.pdf 856 42 $a Midwest Roadside Safety Facility $3 Online Access $z Project webpage $u http://mwrsf.unl.edu/reportresult.php?reportId=313 856 42 $a Midwest Roadside Safety Facility $3 Online Access $z MwRSF Research Hub $u http://mwrsf.unl.edu/researchhub.php 856 42 $a Midwest Roadside Safety Facility $3 Online Access $z MwRSF Homepage $u http://mwrsf.unl.edu/ 941 $a 1 952 $l IAOX771 $d 20240710103148.0 956 $a http://locator.silo.lib.ia.us/search.cgi?index_0=id&term_0=F8D33D3AB7CA11EC864CB83724ECA4DB 994 $a C0 $b UIGInitiate Another SILO Locator Search
