Keywords: beams bond strength bundled glass fiber-reinforced polymer (GFRP) bars design recommendation moment-curvature analysis splice length. In traditional construction methods, contact lap splices are more commonly used because it o ers the most reliable method of ensuring the lapped sections are secure against displacement, especially during concrete pours. Finally, a design recommendation is proposed based on the experimental results and observations that might provide a significant improvement in the safety level for lap-spliced bundled GFRP bars. Their general behavior in terms of splice length effect, failure mode, bar-size effect, and stress distribution, however, appeared to be similar. International Building Code (IBC) is a registered trademark of the International Code. In addition, the bond strength of individual bars in a bundle was lower than that of single bars. architects and specifiers have discovered, lap splicing has very. Therefore, masonry contractors need to be aware. Moreover, the splice strength was found to be inversely proportional to the bar diameter. Additionally, the International Building Code (IBC) does not allow lap splices for bars larger than No. CRSI’s Reinforcement Anchorage and Splices includes tables of required lap splice lengths based on these variables. The length of the lap varies depend on concrete strength, the rebar grade, size, and spacing. The results indicated that the bond strength of lap-spliced bundled GFRP bars was not linearly proportional to the splice length. Lap Splices A lap is when two pieces of reinforcing bar (rebar) are overlapped to create a continuous line of rebar. The studied parameters included the splice length, bar diameter, and number of bars within a bundle. The experimental program was comprised of 11 full-scale beam-splice tests and aimed at providing more insights into the design parameters that might affect the splice strength of bundled GFRP bars. 13/ASCE 5-13: Building Code Requirements for Masonry Structures (MSJC 2013a). ![]() Abstract : This paper reports on the tensile lap splicing of bundled glass fiber-reinforced polymer (GFRP) bars and their bond behavior in unconfined concrete.
