Investigation of splice-plate connections with multiple bolt rows between the beam flanges
Abstract
Splice-plate connections subjected to high moments require larger bolt areas and thus more bolt rows to accommodate a larger number of smaller size bolts. Yield line mechanisms considering the presence of the beam web, were developed to determine the plate thickness. An analytical bolt model for estimating the maximum bolt force was also developed. A design parameter based on the above mechanisms and bolt model was proposed. A computer program was written to carry out the necessary computations and a sensitivity study was conducted to study the effects of the location of bolts and number of bolt rows. A parameter study was conducted by two dimensional finite element analysis and from the results prediction equations were developed for estimating connection rotation, critical plate stress, and bolt forces at any desired load level. Five prototype specimens with plate thicknesses designed according to the proposed procedure were tested, and data on the rotation, plate strains, beam strains near the connection, bolt forces, and deflections were obtained.
