Welded splice connections join truss chords transitioning between different member thicknesses. The offset flange transition detail utilizes a 2.5 to 1 slope on the larger chord flange to match the smaller chord flange, reinforced with a cover plate per elevations and complete joint penetration welds. The centered flange and web thickness transitions provide specific weld sizing based on the thickness ratio where T1 is greater than or equal to 2.5 times T2, or less than 2.5 times T2. Complete joint penetration welds join the abutting chord elements together with transitions detailed to manage stress concentrations.
