Steel Connection - Tutorial 1

This document contains 11 questions related to the design of steel connections using butt welds, fillet welds, and eccentric welding connections. The questions cover topics such as determining the safety of single-V and double-V groove welds, calculating the design bending and shear strength of groove welded joints, sizing fillet welds for tension connections, designing welds for truss members and gusset plates, and calculating loads for eccentric welded bracket connections. Materials properties and forces acting on the connections are provided. The designer is to size and check the adequacy of various welded joints and connections.

Butt (Grooved weld)

1) Two plates of 16 mm and 14 mm thickness are to be joined by a butt weld. The joints is
subjected to a factored tension force of 430 KN. Due to the some reason the effective length of
the weld that could be provided was 175 mm only. Check the safety of the joint if,
a) Single – V groove weld is provided.
b) Double – V groove weld is provided
Grade of steel Fe 410, fy= 250 MPa, Plates to be shop welded.

2) A groove weld is to connect two plates 180 mm X 18 mm each. Determine the design bending
strength of the joint, if it is subjected to a moment of 13 kN-m. Also, determine the adequacy of
the joint if the shear force at the joint is 200 kN. Assume the welds to be of double – U, shop
welded, for Fe 410 steel, fy= 250 MPa, fu= 410 MPa.

Fillet Weld

3) Determine the size and effective length of the side fillets to connect two plates with cross
section of 150 X 10 mm and 100 X 10 mm, which are subjected to tension of 125 kN at working
load. The ultimate strength of the plate fu= 410 MPa.

4) Determine the size of end fillets to connect two plates with cross sections of 125 x 8 mm and
125 x 12 mm, which are subjected to a tension of 100 kN at working load. The ultimate strength
of the plate fu= 410 MPa.

5) In a truss angle 100 x 100 x 8 is subjected to the factored tension of 200 kN. It is to be connected
to a gusset using fillet welds at the toe and back. Find the length of welds required so that the
center of gravity of the welds lies in the plate of the center of the angle. Fu= 410 MPa

6) A tie member consisting of an ISA 80 x 50 x 8 mm. Fe 410 grade steel is welded to a 12 mm thick
gusset plate at site. Design welds to transit load equal to the design strength of the member.
Fy= 250 N/mm2
a. If the weld is to be done in its two side
b. If the weld is to be done in its three side

7) A tie member of a truss consists of double angle section, each 80 x 80 x 8 mm welded on the
opposite side of a 12 mm thick gusset plate. Design a fillet weld for making the connection in the
workshop. The factored tensile force in the member is 300 kN.

8) An ISLC 300 @ 324.7 N/m (Fe 410 grade of steel) is to carry a factored tensile force of 900 kN.
The channel section is to be welded at the site to a gusset plate 12 mm thick. Design a fillet
weld, if the overlap is limited to 350 mm.

Eccentric Welding Connection

9) Design a connection for a bracket using following welding to carry a factorial vertical load of 200
kN acting at 300 mm from the face of the column. The grade of the steel is E250, thickness of
the bracket is 12 mm.
a. Using Butt Welding. Site weld
b. Using Fillet Welding. Site weld

10) Design a connection of bracket connected in the plane of the flange of a column by fillet weld.
The width of the flange of the column is 200 mm. fy= 250 MPa and fu= 410 MPa. Thickness of
the bracket is 12 mm.
11) A bracket plate is used to transfer the reaction of a beam to a column flange as shown in fig. The
bracket plate is connected to the column flange by a 6 mm fillet weld. Compute the maximum
load that can be placed over the bracket plate at a distance of 75 mm from the flange of the
column section.
