Load test was conducted on the Memorial Bridge
October 27, 2017
In the morning of October 27th, 2017, a load test was conducted on the south fixed span of the Memorial Bridge. For loading of the bridge, an NHDOT dump truck loaded with Jersey barriers passed the bridge several times on both the northbound and southbound roadways. The test included five pseudo-static and five dynamic runs. The load test data captured by the mounted sensors on the Portsmouth side were used for calibration of the finite element models of the Memorial Bridge.

The structural sensors on the Vertical Guide Posts (VGP) of the Tidal Turbine Platform System (TTPS) were installed in October 2017. The collected data will be used to a) verify design assumptions for the TTPS mounted on the bridge pier cap, and b) compare the strains predicted by the numerical models with the collected strains to support operational decision-making guides for the operating tidal turbine.

The final instrumentation plan for the structural health monitoring was discussed at the June 28, 2016 technical advisory group meeting in Concord, NH, and was approved on July 18, 2016. The structural sensors were installed on the bridge structure in March 2017 and the installation was completed on March 8, 2017.

February 1, 2016
In February 2016, the Living Bridge research team under supervision of the project PI, Prof. Erin Bell concluded the instrumentation plan design. Strain and acceleration data were collected from six separate parts in three different locations of the Memorial Bridge, (1) top of the lift tower, (2) base of the lift tower, and (3) mid-span gussetless truss connection. These data were used to determine the optimal sensor types and locations for structural health monitoring and support developing of structural models.
