Lug angle and tension splice - Introduction

 Lug angle -

• Lug angle is an angle section of short length which connects the outstanding legs of angle section or member to the gusset plate. 
• It reduces the length of connection to the gusset plate and also reduces the shear lag effect. 
•  When the lug angle is used, the unconnected length of main angle acts like a connected leg and hence entire cross-section area start resisting the tension. Thus, shear lag effect reduces and efficiency of the tension member increases. 
•  Lug angle provides extra gauge line to accommodate the numbers of bolts.
   
  

Tension splice -

• Tension splice are the cover plates used on both sides of butt jointed members.
• A tension member is spliced when the length of section available is less than that of tension member required.
• when the members of different thickness are spliced, packing is required to fill the gap.
• The area of splices should be slightly more than that the member joined.
• It is also used when the size of the member changes at different lengths.
