Experimental and Finite Element Investigation of Bolted Connections in GFRP Composite Cross-Arms for Energy Distribution Towers.

However, the 4% elongation and 1 mm elongation criteria do not indicate a clear trend. Differences among the load capacities determined using the three criteria explained above are relatively small for the GFRP thicknesses of 5 mm and 6 mm ( Figure 11 a), however the differences become more pronounced with further increase in the thickness.
