| Description: | EMBRACE PROJECT AIMS TO THE DEVELOPMENT OF A DISRUPTIVE, "HIGH-RISK, HIGH-GAIN," MODULAR FOUNDATION SYSTEM UTILIZING FRICTION-BASED STONE PILES FOR THE ENHANCEMENT OF HISTORIC BRIDGE RESILIENCE UNDER ADVERSE CONDITIONS SUCH AS SCOUR, FLOOD, AND EARTHQUAKE. ITS PRIMARY OBJECTIVES ARE: (A) BUILD UPON EXISTING EXPERIENCE AND EXPERIMENTALLY VERIFIED CONCEPTS OF LOW-COST SEISMIC ISOLATION DEVELOPED BY THE RESEARCH TEAM TO TRANSFORM THEM INTO A TANGIBLE AND EFFICIENT FOUNDATION STRENGTHENING SCHEME THAT CAN GREATLY IMPROVE THE RESILIENCE OF HISTORICAL BRIDGES, (B) PROPOSE AN INNOVATIVE FOUNDATION STRENGTHENING SYSTEM WHICH IS ABLE TO RESIST VERTICAL LOADS OF THE BRIDGE WITH ADEQUATE SAFETY, WHILE ISOLATING THE SUPERSTRUCTURE FROM THE VERTICALLY PROPAGATING SEISMIC MOTION, (C) ENSURE THAT THE PROPOSED SCHEME IS EFFICIENT ACROSS MULTIPLE HAZARDS SUCH AS EARTHQUAKES, FLOODS AND SCOUR, (D) OFFER A RETROFITTING OPTION THAT SATISFIES KEY PRESERVATION PRINCIPLES SUCH AS [12]: RESPECT FOR AUTHENTICITY, MINIMUM STRUCTURAL INTERVENTION, COMPATIBILITY, RE-TREATABILITY (I.E., A PRESENT INTERVENTION SHOULD NOT COMPROMISE FUTURE INTERVENTIONS), REMOVABILITY (THE ABILITY TO REMOVE CHANGES IF NEW TECHNOLOGIES ARE DISCOVERED IN THE FUTURE), AND DURABILITY, (E) MAKE USE OF A RENOWNED SHAKING TABLE FACILITY IN GREECE TO PROVIDE EXPERIMENTAL JUSTIFICATION FOR THE NEW CONCEPT INTRODUCED, (F) USE THE RESULTS OF THE ADVANCED COMPUTATIONAL ANALYSIS AND THE LARGE-SCALE EXPERIMENTAL CAMPAIGN TO FORM GUIDELINES OF APPLICATION THAT INCLUDE FEASIBILITY. THE EMBRACE PROJECT REPRESENTS A PIONEERING EFFORT IN THE REALM OF HISTORIC BRIDGE PRESERVATION, COMBINING EXPERIMENTAL AND COMPUTATIONAL APPROACHES TO CREATE A RESILIENT AND ADAPTABLE FOUNDATION SYSTEM CAPABLE OF WITHSTANDING A SPECTRUM OF ENVIRONMENTAL CHALLENGES |
