In this paper, the influence of multiple web openings on RC footing beams is investigated. Three-dimensional finite element analysis considering the non-linearity of both concrete and rebar is used. Simulation analysis of previous experiment is firstly conducted for the evaluation of the accuracy of our analysis. Stress conditions and crack distributions between experiment and analysis are compared. Further analyses are conducted with new model with different arrangement of small unreinforced openings. Finally, the influence of small web openings to the beam stiffness and strength is discussed.
