  • Abstract:
    "Executive Summary: Computational methods and associated software were developed

    to compute stresses in HP concrete composite bridge decks due to temperature, shrinkage, and

    vehicle loading. The structural analysis program uses a layered finite element model. Before

    running the structural analysis code, layer-by-layer time history temperatures due to hydration

    heat are computed using a thermal finite element analysis program. Nodal coordinates for the

    thermal finite element analysis are generated from the layer thicknesses of the structural analysis

    finite element model. Autogeneous shrinkage, drying shrinkage, and stress relaxation due to

    creep are taken into account using models based on HP concrete test data. The software

    computes time-history residual stresses for 28 days. After 28 days an HS25 vehicle load is

    additionally applied. Longitudinal stress levels are printed layer by layer for comparison with the

    modulus of rupture and assessment of cracking. A composite bridge specimen was built in the

    structures testing lab in Clarkson University with thermocouple and strain gage instrumentation.

    After monitoring temperatures and strains for 28 days, the test specimen was loaded by a

    concentrated load applied by universal testing machine. Cracking under loading was observed

    and monitored. Software predictions were compared with test data. A one-day training course

    was conducted in Albany for NYSDOT engineers on August 3, 2011 to communicate the

    research findings and recommendations as well as provide training for the use of the developed
