Abstract:

Nonlinear, static finite element analyses are being used for correlation with experiments conducted on one-story reinforced masonry shear walls, and for the prediction of and correlation with experiments conducted on two-story reinforced masonry shear walls with reinforced concrete floor diaphragms and coupling beams. This paper presents calculations conducted on two-story reinforced masonry shear walls with coupling beams and gives comparisons with preliminary data from a recently completed experiment. The final data package from the test has not been completed at this time, and in-depth comparisons between the analyses and test require more of the data. Preliminary comparisons of peak base shear indicate that the full width of the floor diaphragms may not be effective in the two-dimensional finite element simulation of the coupled walls. Displacement comparisons are not possible until the measured displacements are corrected for base slip.
