Structural Modeling, Instrumentation, and Load Testing of the Tobin Memorial Bridge in Boston, Massachusetts
This paper describes analytical structural models created for various components of the Tobin Memorial Bridge, and a program of instrumentation and non-destructive testing for the Little Mystic Span. A detailed global finite element model of the Little Mystic Span, one of the two truss spans, was developed along with supporting special studies of continuity and boundary conditions. Special studies include modeling the rotational stiffness of the truss connections and consideration of the piers and bridge shoes. An instrumentation plan was developed and deployed for the Little Mystic Span to capture structural responses of key truss members. Nondestructive testing using loaded trucks was carried out for the purpose of model verification and calibration. Preliminary comparisons between experimental and analytical strains for key truss members show reasonable agreement. Special study results will be used to fine-tune the global finite element model. The verified models may be used as a condition assessment program and structural health monitoring system for the management of the Tobin Memorial Bridge.
