The aspect ratio of the test walls was 2.2. The effects of lap splices, splice length (60 bar diameters and 40 bar diameters), and boundary-element confinement were studied. I made the semi-graphical solution shown below. Six large-scale reinforced concrete structural walls were subjected to increasing displacement reversals up to failure. Redraw the shear and moment diagrams for the beam.

Redraw the free body diagram with the UDL and the point loads on the beam where each of the four fasteners are located. Moment at the splice location is 49.0 kip-ft.įor simplicity, the spice plates are connected to the beam with two fasteners on each side of the splice location.Įach pair of fasteners form a couple resisting 49.0 kip-ft. The splice is located 7' from the left end. An example is clearer than words:Īssume a 21' long spliced beam with simple supports, supporting a UDL of 1 kip/ft. 5, the filler 430 and an end 520 of the lip 414 are separated by a gap 522. 5, which is a zoomed in view of the lap join 350 of FIG. Assume no friction between beam and splice plates. Further details of the circumferential splice 390 are provided with respect to FIG. The couple on each side of splice have opposite signs. nVent LENTON Quick Wedge is a simple and quick alternative for joining small diameter reinforcing steel bars (rebar). On both sides of splice location, the fasteners form couples each couple resists moment equal to what would have been present in the beam at the splice location. were the concrete compressive strength, the lap splice length, the amount of transverse reinforcement provided. Sturctee - The beam at the splice location can not resist moment.
