The following are the statements about lug angle used to connect heavily loaded tension member to gusset plates. (i) The length of end connection is reduced (ii) By using lug angles there will be saving in the gusset plate (iii) Cost of connection increases due to additional fasteners and angle required.
Only (i) and (iii) statements are correct
Statement (i) is correct because lug angles reduce the required length of the tension member connection. Statement (iii) is correct because the additional material and fasteners for the lug angle increase the cost of the connection. Therefore, the correct answer is Only (i) and (iii) statements are correct.
Important Questions from Tension Member
A single angle in tension is connected by one leg only. If the areas of connecting and outstanding legs are respectively a and b, then what is the net effective area of the angle?
A) \(a-\frac{b}{1+0.35\times\frac{b}{a}}\)
B) \(a+\frac{b}{1+0.35\times\frac{b}{a}}\)
C) \(a-\frac{b}{1+0.20\times\frac{b}{a}}\)
D) \(a+\frac{b}{1+0.20\times\frac{b}{a}}\)
