Determination of beam-to-column connection characteristics in pallet rack structures: a comparison of the EN and ANSI methods and an analysis of the influence of the moment-to-shear ratios

摘要

he beam-to-column connections in most of the pallet rack structures made of thin-walled\udsteel sections are of the clip-on type. These connections are of a semi-rigid nature and\udhave a non-linear moment–rotation relationship, which has to be determined experimen\ud-\udtally. The experimental methods described in the European standard (EN 15512: 2009) and\udthe American standard (ANSI MH 16.1: 2008) are different. This paper presents a series\udof test results determining the beam-to-column connection characteristics of European\udand American origin, tested with both methods. This is followed by a comparison and\udanalysis of the results. The influence of the distance from the applied load to the face of\udthe upright, i.e. the influence of the moment-to-shear ratio, is also analysed and discussed
