abstract="The history of barrel/W-section construction barriers is traced. Three crash tests conducted by Southwest Research Institute are analyzed to indicate a probable performance zone for the current barrel/W-section design. This design is the 12-gauge W-section mounted on barrels spaced at intervals of 6ft 3 in (1.91 m) and filled with sand. Three new designs of barrel/W-section barriers are presented. By using a formal comparative structural analysis, the conventional design and the three new designs are analyzed and predictions are made of comparative performance. Stabilized barrel/W-section 3 is shown to perform at much more critical levels of impact than the current barrel/W-section barrier does. However, its use is applicable where large deflections can be accommodated.<p />",
