Hi!,

While performing basering analysis for a vessel in Analyze Option
the result is as below:
Required Area for Each Bolt, Based on Max Load 7.2919 cm²
Area Available in a Single Bolt (Corr) 3.5548 cm²
Area Available in all the Bolts (Corr) 42.6580 cm²
Bolt Stress Based on Approximate Analysis 285.7 N./mm²
Allowable Bolt Stress 139.3 [Fact] 139.279 N./mm²

i.e Insufficient Anchor bolt area.

and with the same inputs i tried Brownell & Young analysis method, the results with this analysis is passed.

Please advice if i can use the Brownell & Young analysis method instead of only Analyze option.

Is there any criteria to use any of the above methods?

Thanks in advance for your time in this matter.

Best Regards.

Raghav,

Did you choose Neutral-Axis shift method with the "Analyze" option.

The Brownell and Young method is based on Neutral Axis shift method (steel on concrete).

I have choosen "Simplified or Steel on Steel" for "Analysis" option and Neutral-Axis shift for Brownell and Young.

The Brownell and Young option utilizes the Neutral-Axis shift method which accounts for difference in the Young's mod. of steel versus concrete.

They will give you different results. I will suggest that you read about Neutral-Axis shift method in the literature.

You have to use the option that applies for your case, if you have steel on steel then you the simplified method and if you have steel on concrete then you the Neutral-Axis shift method.
