Strut-and-tie models were developed for beam-column joint in soft-first story where first-story columns were extended toward outside. The developed models agreed with the observed crack patterns. The developed models were different from those for knee joints in that large struts were extended into the second-story column and the wall panel. Based on the strut-and-tie models new design equations were proposed, where the joint strength is evaluated as the sum of the flexural strengths of the beam and the second-story column.
