Abstract: Carbon-based nanomaterials are currently used to reinforce cement-based composite materials based on their superior properties. However, the mechanical performance of the cement-based composite materials can be improved ...

Abstract: Steel degradation due to corrosion in prestressed concrete bridges has been of major concern as it presents a threat to the integrity of structures adjacent to marine environments or where deicing salts are regularly used. ...

Abstract: This paper presents the development and validation of a cyberinfrastructure architecture for research in nondestructive evaluation (NDE) using acoustic emission (AE) data. Existing cyberinfrastructures for civil engineering ...

Abstract: Current American Society of Mechanical Engineers (ASME) provisions require that acoustic emission testing for class II vessels be carried out at operating temperature in the event that the ...

Abstract: A live-load test was conducted on an in-service bridge containing flat precast concrete slabs. The purpose of the test was to evaluate transverse load distribution and efficiency of the longitudinal slab-to-slab joints. ...

Abstract: The effect of steel reinforcement on the distribution of alkali-silica reaction (ASR) damage in concrete blocks is studied by leveraging acoustic emission sensing with a data-driven approach. The innovation lies in deriving ...

Abstract: South Carolina has thousands of decades-old precast concrete slab bridges that were designed carry loads smaller than those designated in current standards. This paper presents an experimental program that investigated two ...

Abstract: Acoustic emission was used in this study to assess the condition of a simple-span, prestressed concrete bridge located in southern New Mexico during a proof test. The 40-year-old bridge is county owned and no design plans ...
