Abstract:Presents formulas for use in the analysis of flexible baseplate anchorages based on the study of an extensive series of tests performed on connections of varying flexibilities. The formulas presented were evolved from computerized comparisons of calculations with all test data to develop the most uniform fit. Of particular interest is the effect of plate stress on the location of the compressive reaction and redistribution of loads to anchors, and the effect of preloading of anchors on performance and capacity of the anchorage. Comparisons of measured and calculated test results are presented for varying moments ranging up to the capacity of both flexible and rigid base-plate anchorages. Recommendations are given for designing ductile anchorages, preloading anchors, and combining the frictional resistance of the compressive reaction with anchor shear capacity in determining shear resistance.
