a. Step 1: Design fillet weld connecting each truss bar and gusset plate
The maximum normal load in a truss bar is N max (considering both tension and compression
load).
Based on [1] – chapter 2,
2, personally, the stages are
are:
The load acts to fillet weld is divided in to 2 component loads: N1 and N 2
With N1 = k × N and N 2 = (1- k)× N
election of electrode grade for fillet weld: N42 or N46, from that the value
From the sselect
election
( .f w ) min can be determined.
Select preliminary size of filet weld:
weld h f 1 andh f 2 which are satisfied requirements
about the allowable maximum and minimum sizes of filet weld.
Calculate required
required length for each fillet weld:
L w1
andL w 2
2(f w ) min h f 1 c
2(f w ) min h f 2 c
It is better if to reduce the sizes of gusset plate, required length for each fillet weld is as the
smallest value as possible (50 mm), and the corresponding size of fillet weld is adaptable.
Also, to increase the rat
ratee of welding process , the sizes of these fillet welds should be equal.
b. Step 2: Design preliminary shape of gusset plate
The shape of gusset plate depend on various factors including: section of truss bars, angles
between
between each bar with column and between each two truss bars, the required length of each
fillet weld which connecting
connecting truss bars and gusset plate, etc.
esigning
ing a good preliminary shape of gusset plate is shown as

Determine
Determine load acts to fillet weld:
In this case, it is a resultant load of normal loads into the diagonal member and bottom
chord.
