ABSTRACT

Two beam sizes, W14X38 and W8X21, were used in the test program. For the 14-inch sections, the overall beam length was 20 feet, and for the 8inch sections, 12 feet, so that the span-to-depth ratio was slightly less than 20 in each case. The stub column.for the W14X38 beams was a W12X96 section; a W12X58 column section was used with the W8X21 beams. Heavy column sections were selected to minimize column panel zone deformation, thereby confining the deformations to the connection elements. Details of the W14X38 and W8X21 connections are shown in Figs. 1 and 2, respectively.
