Abstract:

Numerical modeling is being implemented because experiments are challenging, unwelcome, costly, or timeconsuming. The main goal of this research is to study the influence of the maximum aggregate size on the ultimate load of the pre-tensioned prestressed concrete beam with multiple layers of strand and shear reinforcements under flexural loading numerically. This was done by validating one finite element model based on experimental results of a standardized fourpoint static bending test previously reported. Subsequently, four beams with different maximum aggregate sizes were simulated using ATENA 3D software. The finite element analysis could simulate the experimental tests and provide meaningful results. Moreover, a slight increase in the ultimate load of the member was observed with a larger maximum aggregate.
