Presented in this paper is a study to show that the Hart-Smith semi-empirical modeling approach can be used to predict the net-tension strength of multi-rowed experimental-to-theory strength ratios are < 1.0, and only one of these two could be said to have predicted unsafe net-tension strengths. With none of the ratios exceeding 1.2, it is seen that the simple and versatile modeling approach gives very acceptable predictions. To determine the modeling parameters that will enable the Hart-Smith approach to be in a LRFD design standard there is a need for a comprehensive series of strength tests, for net-tension failure with filled-and open-holes, that covers the complete range of multi-rowed bolted connections that is to be permitted by the standard.

The present study investigates the effect of different thicknesses of steel and fiber reinforced polymer (FRP) cover plates on the mechanical behavior of bearing-type multi-row bolted connections for FRP composite structures. Connections with a double-lap configuration up to four rows of bolts subjected to tensile loads have been studied numerically. These numerical data are examined in detail to understand the effects of cover plate stiffness on load distributions among rows of bolts. The study also considers the influence of geometric parameters on the load distributions. For validation of the connection model, numerical results are compared with experimental results available in literature. The results show that the load distribution in bearing-type multi-row bolted connections is significantly affected by the cover plate stiffness. A connection with higher cover plate stiffness tends to show lower efficiency. For a connection with steel cover plates, to increase number of bolt rows more than three does not lead to a higher capacity of a connection. The results also indicate that effect of geometric parameters on the load distribution is not significant with change of cover plate stiffness.

A brief overview of some of the more noteworthy PFRP structures is presented. It is noted that, at the present stage of development, bolted connections are used extensively in fabricating structural frames from PFRP sections. Tests on bolted connections between PFRP sections, i.e., axially loaded and moment connections, and guidance for their design are reviewed. Some areas where further research and guidance are needed are mentioned and the paper is concluded with a few remarks on possible future developments.
