How to set classification for DNV RP-C203

For calculation of fatigue, the type of loading, the different load cycles and the calculation method, rainflow counting vs spectral fatigue calculation and allowable fatigue stress vs direct fatigue damage is important, but also the resistance of the material and in case of welded structures the influence of welds […]

Implementing EN 1993-1-8 (2005) Bolt Check in SDC Verifier

Another great feature of SDC Verifier is described here. Connections made with bolts according to EN 1993-1-8 (2005) Chapter 3 can now be checked with SDC Verifier directly within your standard FEA program. For the EN 1993-1-8 bolt check the following checks can be performed: Shear connection A. bearing type; […]

Checking according to EN13001 standard in SDC Verifier

Crane Standard EN 13001-3-1+A2 Limits States and proof competence of steel structure is implemented in SDC Verifier. The standard is to be used together with EN13001-1 and EN13001-2: EN 13001-3-1 standard deals only with the limit state method. The allowable stress method is reliable in specific cases – for cranes […]

AISC 360-10 Examples

Design Examples of AISC 360-10 Here is the list of examples from Design Examples of AISC (official version 14.1). All examples modeled in Femap and calculated with SDC Verifier. These examples demonstrate that SDC Verifier calculations according to ANSI/AISC LRFD 360-10 standard is valid. You can also download tutorial on […]

Eurocode3 Member Checks

The Eurocode3 rules estimate the risk of global and local buckling limits of the steel beam members with a classification based method. For the explanation of the checking procedure with the SDC Verifier software the beam member below is used.

DIN15018 Fatigue

Fatigue criteria Fatigue is a progressive structural damage of materials under cyclic loads. Most of engineering failures are caused by Fatigue that is why it is very important to perform a Fatigue Check. SDC Verifier implement two methods of Fatigue Check: the stress difference method the stress difference method with […]

EN280/13001

Four checks accroding to EN280/13001 were performed for Crane: Static strength, Static strength for welds, Fatigue check and Fatigue check for welds.

ISO 19902

For checking of large (offshore) lattice structures according to ISO 19902 the joints and members need to be recognized in the standard FEA model.

ABS 2004 and 2014 Comparison

SDC Verifier implements 2 different ABS plate buckling checks: Guide for Buckling and Ultimate Stress Assessment for Offshore Structures, APRIL 2004 (Updated February 2012): ABS 2004 Rules for Building and Classing Floating Product Installations, July 2014: ABS 2014 There are 3 small differences in calculation of Ultimate Strength Limit. Buckling […]

Allowable fatigue stress

For cranes as for most other dynamically loaded structures very important. The allowable fatigue stress depends on the following: The material (or the elasticity limit) of the construction. The sign of the stress (tension or compression). The k-factor (the ratio between the maximum and the minimum stress). The number of […]
