Strut and tie method verification with non-centrally loaded deep beams.

This study examines the impact of three distinct loading scenarios that are not centrally located on twelve deep beam specimens made of reinforced concrete. These specimens were split up into three groups, and the SAP2000 software was used to evaluate each group using the finite element method. The loading categories that were taken into consideration were one-point load (Group A), two-point load (Group B), and a partially uniformly distributed load (Group C). Each of the three types of loading was moved away from the middle of the span by a quarter of its length. It has been found that the load capacity and midspan deflection decrease by 9-17%, 9-13%, 18-11% and 40-22%, 35-44%, 26-21%m respectively when the 1-point load, 2-point load, and the partial uniformly load are moved away from the beam center. It has also been found that the effect of load decentralization increases when the concrete compressive strength is doubled. Finally, the performance of Strut and Tie method, ACI 318-19 was investigated when moving the load, along with the results the finite element method gives. [ABSTRACT FROM AUTHOR]
