The invention discloses a simple calculating method for lacing bars of a frame structure infilled wall. The simple calculating method comprises the steps that firstly, seismic shear force borne by each layer of a building is calculated, then the number of wall segments of the infilled wall of all the layers which participating in resisting the horizontal seismic shear force is determined, then theseismic shear force capable of being resisted by all the wall segments between the layers is determined, then the remained seismic shear force V of the r layer is determined, the remained seismicshear force V of each layer needs to meet the formula that V is less than or equal to 2n*omega*P, taking the formula that V is less than or equal to 2n*omega*P as the precondition, the lacing bar design scheme that the using number of the lacing bars is the least, and the layer-to-layer space between the lacing bars is not more than 1000 mm according to the design standard requirement of masonryis selected, and the type of the selected lacing bars is determined. The simple calculating method for the lacing bars of the frame structure infilled wall overthrows the arrangement form that the lacing bars are arranged according to the structure in a traditional design idea, seriously-unreasonable traditional arrangement of the lacing bars is proved, meanwhile, traditional convention that the lacing bars are not required to be calculated is abandoned, the lacing bars are required to be determined through simple calculation, it is ensured that the infilled wall does not collapse under frequently occurred earthquakes, the drilling work amount of embedded steel bars is greatly reduced, and economic benefits are increased.
