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.
After being outside and exposed to the elements during many years of service, concrete and the reinforcement within begins to deteriorate and corrode,...
This project developed structurally independent foundation designs for 54-inch tall single slope concrete barrier (SSCB) for shielding bridge columns ...
