engineering recuitment GATE CE 2023-24 Test Series Design of Steel Structures Structural Fasteners Bolted Connections
A bolt is subjected to a shear stress of fab and a tensile stress of ftb. If the permissible stresses in shear and tension are fasb and fatb respectively then the stress should satisfy:
1
\(\frac{{{f_{sb}}}}{{{f_{asb}}}} + \frac{{{f_{tb}}}}{{{f_{atb}}}} \le 1.0\)
2
\({\left( {\frac{{{f_{sb}}}}{{{f_{asb}}}}} \right)^{1.4}} + {\left( {\frac{{{f_{tb}}}}{{{f_{atb}}}}} \right)^{1.4}} \le 1.0\)
3
\(\frac{{{f_{sb}}}}{{{f_{asb}}}} + \frac{{{f_{tb}}}}{{{f_{atb}}}} \le 1.4\)
4
\({\left( {\frac{{{f_{sb}}}}{{{f_{asb}}}}} \right)^{2}} + {\left( {\frac{{{f_{tb}}}}{{{f_{atb}}}}} \right)^{2}} \le 1.0\)
