CAD fabrication drawing for Steel Beam Reduced Size Welded Splice Connection Detail. Two ( 2 ) consecutive difference size IPE steel profile sections, IPE400 to IPE360, connected together with a full penetration butt weld splice connection.
Reducing the size of the beam is very a common practice in order to reduce the selfweight ( dead-load ) of a structure. Usually beam splice connections are carried out at the 1/3 of the beam span.
The two ( 2) consecutive steel beams are connected together using an intermediate custom profile ( cut from the bigger section ), shop welded together with a full penetration butt weld to ensure continuity. The use of this intermediate section is for ensuring smooth transfer of loads between the two sections.
