【Abstract】 A simplified model to calculate uneven settlements and internal forces in RC frame filled with brick wall is proposed in this paper,considering superstructure-foundation-soil interaction.The interaction between columns and filled masonry is taken into account by simplifying the brick wall as compression diagonals,and the interaction between foundation and soil is taken into account by simplifying the soil below foundation as elastic-modulus-varied axial compression bars.The calculation results for a mill building located in Shanghai have good match with that observed in the site.更多还原
