#### shear lag effects in angles welded at both legs

### - General CISC-ICCA

Its shear lag effect is given as a function of the ratio of the eccentricity of the weld with respect to the centroid of the outstanding leg, x, to the weld length, L. Then the tensile resistance of the member is calculated in accordance with Clause 13.2(a)(iii) using the total effective net area of the angle section, A ne = A n2 + A n3.

Thornton (1995) assesses the ductility of bolts in the outstanding legs of double-angle and similar simple-shear connections. This study validates the long-standing AISC Manual recommendation that maximum angle thickness be limited to 58 in. for usual gages (4½ in. to 6½ in.) in double-angle simple-shear connections. An Experimental Study of the Influence of Eccentricity on This paper presents an experimental study on the shear lag effects in longitudinally welded tension members under both in-plane and out-of-plane eccentricity through the testing of eight 3×1/2 plate sections and twelve 3×3×1/2 single-angle sections having both equal and unequal longitudinal weld lengths. Experimental shear lag factors were

Example 3.2 A single angle tension member, L 4 x 4 x 3/8 in. made from A36 steel is connected to a gusset plate with 5/8 in. diameter bolts, as shown in Figure below. The service loads are 35 kips dead load and 15 kips live load. Determine the adequacy of this member using AISC specification.

outstanding leg are subjected to local bend due to shear lag effect. Application:Angles are used in a variety of structures such as trusses, transmission towers etc. as tension members. Angles may be used as single angles or double angles and the connection may be bolted or welded. Study on Behaviour of Bolted Cold-formed Steel Angle Tension Influence of shear lag on ultimate tensile capacity of May 01, 2013 · where is the capacity factor, taken as 0.9 for member under tension; A g is the gross area of the cross-section; k t is the correction factor for distribution of forces (i.e. shear lag effects), taken as 0.85 for equal leg angles and unequal leg angles connected by the long leg, or 0.75 for unequal leg angles connected by the short leg, or 0.9 for tee members; A n is the net area of the cross-section, which is equal to the gross section in members with welded

### LUG ANGLE :CONCEPT AND DESIGN

Always longer legs are connected to gusset plates because there is no shear lag effect in the connected leg. Due to shear lag effect, outstand legs are less effective in transferring the tension. So shorter legs are kept as unconnected legs. Design of lug angle means fixing the size of lug angle and finding the no. of bolts at location 1, 2 and 3.

shear lag, and the effect of gusset plate thickness is negligible because of the symmetric connection. The ultimate tensile capacity of the suggested connection in this study were compared to the typical RHS connection presented in the AISC and the similar double angle sections connected at both legs. Shear Lag Effect in Welded Single Angle Tension Member Apr 15, 2021 · The typical failure of a welded single angle tension member is a gross section failure. The rupture strength of the single angle tension member is affected by the effect of shear lag. Full-scale tests on twenty-seven single angle specimens reported in this paper. Four different angle sections with four different section types were used in the test.

### Shear Lag Effect on Bolted L-shaped Cold-formed Steel

strength of the critical section of the connected leg and the strength contributed by the critical section of the outstanding leg. Holcomb, LaBoube and Yu (1995) studied both angle and channel sections subjected to a tensile load parallel to their longitudinal axis. The primary intent of the test program was to determine the effect of shear lag. Shear lag and eccentricity effects of bolted connections Abstract This paper examines the three factors approach previously presented by the senior author for determining the net section efficiency of a bolted cold-formed steel open profile. One objective is to ascertain that the net section efficiency is governed by three factors:the in-plane shear lag associated with stress concentration around a bolt hole that is also present in a flat

### Shear lag effect on ultimate tensile capacity of high

This research investigates the shear lag effect on the behaviour and ultimate tensile capacity of high strength steel (HSS) tension angles with bolted and welded connections. Eighteen full-scale tests were conducted, including fourteen specimens with HSS tension angles and four specimens with normal steel (NS) tension angles. Sher lag in double angle truss connections - ScienceDirectJan 01, 2002 · Table 2 shows calculations of the effective net area for both legs of the angles. For all specimens, the width of the connected leg is smaller than twice the weld length and hence there is no reduction in area due to shear lag for that leg. For the outstanding leg, all specimens have an area reduced to a value between 72 % and 78 %.

### 1 2 3 The shear lag effects on welded steel single angle

shear lag coefficients for angles in tension were not affected by the presence of the transverse welds. Uzoegbo [9] concluded that the shear lag effect should be evaluated individually for each leg of the angle specimen based on his test results for steel angles with welded connections. Petretta [10] tested 23 double angle specimens with welded end
