Abstract:This study addressed the need for an aesthetically pleasing historic concrete balustrade design alternative for the Pulaski Skyway in Jersey City, Hudson County. In this study, a crashworthy design was developed according to AASHTO Section 13 specifications and was modeled using the nonlinear transient dynamic finite element analysis software, LS-DYNA, and the AASHTO Manual for Assessing Safety Hardware (MASH) TL-4 collisions were simulated. Crash tests were performed successfully at the Texas A&M University Transportation Institute (TTI). The computer simulations were updated to match field testing conditions, and were then validated according to the procedures set forth in NCHRP W179: Procedures for Verification and Validation of Computer Simulations Used for Roadside Safety Applications. The state of New Jersey now owns a historic looking barrier that can be used on any corridor in the U.S. which requires the containment of a single unit truck. The validated models can be used to evaluate retrofits or small changes without the need for additional crash tests.
