Strut-and-tie models were developed for beam-column joint in soft-first story where first-story columns were extended toward inside. The developed models were different from those for exterior joints in two points: (1) the sign of the shear force in the first-story column was opposite to that in the second-story column and (2) large struts were extended into the wall panel. The diagonal reinforcement was effective to the closing load because it prevented the compressive failure of the concrete in the wall panel. Based on the strut-and-tie models new design equations were proposed.
