Pin/Bolt Safety Check
You can determine if a bolt or a pin in an assembly can safely carry
the applied loads, or if it will fail.
The software calculates the combined load ratio a connector withstands
and compares it with the user-defined factor of safety.
The pass/no-pass check for connectors
is available for linear and nonlinear static studies. For nonlinear studies,
the software displays the pass/no pass status of all pin and bolt connectors
for each solution step.

Axial load ratio |
Ra = F/(At*S) |
F = axial
load calculated by the software
At = tensile area
S = strength value of connector's material or grade (could be yield,
ultimate, proof or shear strength based on application) |
|
Bending load ratio |
Rb
= D*M/(2*S*I) |
M = Bending
moment calculated by the software,
D = nominal shank diameter
S = strength value of connector's material or grade (could be yield,
ultimate, proof or shear strength based on application)
I =0.25*p*r^4 |
|
Shear load ratio |
Rs
= V/(At*S) |
V = Shear load calculated by the software
At = tensile area
S = strength value of connector's material or grade (could be yield,
ultimate, proof or shear strength based on application) |
|
Combined load ratio |
(Ra + Rb)^2
+ Rs ^3 |

|
Connector pass criterion |
1 / ((Ra + Rb)^2
+ Rs ^3) >
SF |
SF = user-defined factor of safety |
|
Connector no pass criterion |
1 / ((Ra + Rb)^2 + Rs
^3) < SF |
