Pad eye design acc to AISC?

Pad eye design acc to AISC?

Pad eye design acc to AISC?

(OP)
Dear Engineers,

In europe we design a pad eye according to the formula of bleich or poocza. This is an very fine tuned method.

How ever our customer in America wants it calculated acc to
AISC 9 th edition ASD or an american regulation.

I can not find a chapter in the AISC 9 th edition ASD, which copes with a pad eye design, where an engineer can calculate, the average stress in the padeye, surface stress from the shaft in the hole, the eye stress and the shear stress in teh pad eye.

The question is, can anybody help me which rules i have the use to design this pad eye.

It may als be calculated according to API 4F.
 
So far thanks,

ir Ilhan Ozturk

RE: Pad eye design acc to AISC?

AISC has some excellent papers on design of Padeyes.
The code has rules within it ,edge distance, thickness, clearance that are relevant for padeye and pin connections. Look under pin connections. etc

RE: Pad eye design acc to AISC?


can you point me in the direction of some papers on bleich or poocza, I have recently started looking at padeye design and these would be quite usefull

RE: Pad eye design acc to AISC?

Hi Ilhan,

I am currently looking at formalising padeye design for my company & would be very interested in having a look at the Bleich and poocza methods. I have had very good results when I apply curved beam theory.

RE: Pad eye design acc to AISC?

AISC quaterly journal published a paper several years ago on the design of lifting beams. Also covered pad eyes.I believe it was by David Pason. Excellent paper. They could probably pull it and send you a copy.

RE: Pad eye design acc to AISC?

In the US the following may help guide guide you:
ASME B30.20a-2001 Structual and Mechanical Lifting devices. Section 20-1.2.2 Construction
CMAA crane requirements
AASHO 1.6.17
Steel Construction Manual-AISC
Occupational Safety and Health Administration (OSHA) 29 CFR standard 1926.753(e)(2) and 1926.251
American Society of Testing and Materials Specifications A391
Naval Facility Command NAVFAC-307
American National Standards Institute, "Below The Hook Lifting Devices"

eBook - Rethink Your PLM
A lot has changed since the 90s. You don't surf the Web using dial-up anymore, so why are you still using a legacy PLM solution that's blocking your ability to innovate? To develop and launch products today, you need a flexible, cloud-based PLM, not a solution that's stuck in the past. Download Now
White Paper - Using Virtualization for IVI and AUTOSAR Consolidation on an ECU
Current approaches used to tackle the complexities of a vehicle’s electrical and electronics (E/E) architecture are both cost prohibitive and lacking in performance. Utilizing virtualization in automotive software architecture provides a better approach. This can be achieved by encapsulating different heterogeneous automotive platforms inside virtual machines running on the same hardware. Download Now
White Paper - The Criticality of the E/E Architecture
Modern vehicles are highly sophisticated systems incorporating electrical, electronic, software and mechanical components. Mechanical systems are giving way to advanced software and electronic devices, driving automakers to innovate and differentiate their vehicles via the electric and electronic (E/E) architecture. As the pace of change accelerates, automotive companies need to evolve their development processes to deliver and maximize the value of these architectures. Download Now
