IMPACT BEHAVIOR OF CONCRETE BEAMS WITH CORRODING REINFORCING STEEL

Summary:
This thesis presents an analytical and experimental investigation of the remaining impact strength of concrete beams with corroding reinforcement. Concrete beams were subjected to impact using a centrally loaded instrumented dropweight system. Three different amounts of steel corrosion were used to simulate ten, twenty, and thirty years of seawater exposure. The first part in the analytical investigation involved the use of the finite element code ADINA. The second included development of three physical models; the first based on a beam impact equation of forced vibration for a pin-ended beam with center span impact, the second a two-degree-of-freedom model, and the third a three-degree-of-freedom model taking into account the stiffness of the supports for the impacted beam specimens. The different analytical results showed good correlation with the test values of the impact energies. Also, the energy values for the different corrosion periods obtained from the ADINA analysis compared well with experimental ones.
