Implementing AISC 360-10 Bolt Check in SDC Verifier

SDC Verifier implements Bolts and Threaded parts (AISC 360-10 Chapter J3. specification). You can easily perform following checks for your FEA Model: Tensile and Shear Strength of Bolts and Threaded parts; Combined tension and shear in Bearing-Type connections; High-Strength bolts in Slip-Critical connections; Bearing strength at bolt holes; SDC Verifier can […]

Checking according to EN13001 standard in SDC Verifier

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 […]

Design with Finite Elements. Lecture 2: How to model with FEM

SDC Verifier is different in the lecture slides than then current SDC verifier  Element stress vs Nodal stress Mesh Size and type Warping and torsion How detailed should the crane be modelled? Modeling details: Stiffeners, Mass distribution, Hinge points and plate hinges, Stiff connections and constraints Modeling: Beam simplification: No […]

Design with Finite Elements. Lecture 6: FEM Calculation Methods

What is a normal deflection of your boom tip I have very small eigenfrequencies what to do / My constraints do not work Forces in SDC & Warping Low eigenfrequencies 0.4 (not small!) how to increase How to stiffen boom What does an offset do? Non-linearities Stress stiffening and spin […]

Design with Finite Elements. Lecture 3: Load according to standards

I cannot mesh because the orientation is colinear with the element orientation Element with zero length Fatal Error: singularities found (how can we find them – Modal analysis to find loose objects) Solve error singularity: Check eigenfrequencies: if eigenfrequencies are 0 there is no stiffness HELP! Split elements: No nodes […]

Design with Finite Elements. Lecture 4: Load combinations according to standards

What to do with the engine room Constraints on bogie set Where to apply constraints Constraints are not working – constraintsets Dimensions of the crane Which loads to apply M-factor Weight info (engine room, structural parts, wind) Hoisting factor Hoisting weight + safe working load Inertia due to movements (trolley […]
