Abstract:
|
When strengthening reinforced concrete slabs with textile reinforced mortars (TRM), the “correct”
consideration of the global bond behaviour between textile and cementitious matrix is identified as
the main challenge in determining the most appropriate global analytical model. The first model
evaluated here is based on classical assumptions for structural concrete design. The second model,
as another extreme assumption, is completely neglecting textile bond in the cracked zone, thus
assuming it as unbonded, end-anchored, external reinforcement. The third model is based on the
simplifying assumption of the textile reinforcement being only significantly activated when the
internal steel reinforcement is yielding. Analytical results from these approaches are compared to a
database containing more than 130 test results reported in literature, and are statistically evaluated.
