Where a specified level of wind resistance is required, plank lap siding shall be attached to solid panel sheathing or framing members, appropriately spaced, with. Splices shall be at least one stud cavity away from door or window openings. Keywords: beams bond strength bundled glass fiber-reinforced polymer (GFRP) bars design recommendation moment-curvature analysis splice length. Splices shall be staggered at minimum 24-inch (610 mm) intervals when located in the same wall cavity. 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. Double-wire joint reinforcement shall be 3 / 16-inch (4.8 mm) diameter and shall be placed in the first two bed joints above the opening. Lap splices of joint reinforcement not less than 12 inches (305 mm). 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. 72db cap on ASD lap splice lengths added consistent with SD. In addition, the bond strength of individual bars in a bundle was lower than that of single bars. Provide double-wire joint reinforcement extending 12 inches (305 mm) beyond each side of the opening. Lap Splices A lap is when two pieces of reinforcing bar (rebar) are overlapped to create a continuous line of rebar. Published on a 3 year cycle IBC International Building Code (our focus for this webinar). Moreover, the splice strength was found to be inversely proportional to the bar diameter. The results indicated that the bond strength of lap-spliced bundled GFRP bars was not linearly proportional to the splice length. The first Swiss Code that included seismic provisions was released in the year of 1970. The studied parameters included the splice length, bar diameter, and number of bars within a bundle. regarding the lap splice performance under cyclic loading. 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. Abstract : This paper reports on the tensile lap splicing of bundled glass fiber-reinforced polymer (GFRP) bars and their bond behavior in unconfined concrete.
