Which of the following does not describe a weld type?
The maximum longitudinal pitch allowed in bolted joints of tension members is
When the effect of wind or earthquake load is considered in the design of rivets and bolts for steel structures, by what percentage the permissible stresses may be exceeded?
What is the safe load Pthat can be transmitted by the fillet-welded joint shown in figure below if the safe allowable shear stress in the fillet weld is 108 MPa?
The safe load that can be transmitted by the fillet welded joint is given by,
A 6 mm thick mild steel plate is connected to an 8 mm thick plate by 16 mm diameter shop rivets. What is-the number of rivets required to carry an 80 kN load?
For shop rivets permissible stresses are, In shearing, τs = 100 MPa
In bearing, σb = 300 MPa
The gross diameter of hole (D)
.= 16 + 1.5 = 17.5 mm
∴ Rivet value = 24.05 kN
Hence, number of rivets required
For field rivets, the permissible stresses are reduced by what percentage?
What is the permissible tensile stress in bolts used for column bases (fy is the yield stress of the steel)?
Permissible tensile stresses in bolts used for column bases is 120 N/mm2.
Which one of the following is correct?
The permissible stresses in a weld are usually taken as
What is the ratio of the yield stress in power driven shop rivets relative to the permissible bearing stress of mild steel?
The yield stress in power drive rivets is 200MPa and bearing stress of mild steel is 250MPa.
What is the maximum permissible longitudinal pitch in staggered riveted compression joints?
