Abstract

A recent research defined the application of Reliability-Based Design (RBD) approach as an improvement compared to the Limit State Design (LSD) in the definition of actions and resistances for the design of hybrid barriers and attenuators. An extensive campaign of full-scale tests on these two types of structures will be carried out starting from the results of this research for the definition of the general arrangement, the testing procedures and the targets. In this paper the details of the field test, properly studied and arranged for this purpose, and the set up for the first series of tests are presented. The numerical model of the structures, calibrated based on the full-scale tests, will be used as a tool in future studies for simulating the real behavior of these structures during and after impacts, with the main purpose of defining a reliable design approach.
