stiffnesses

EK385

The load should not be shared between welds and fasteners of different stiffnesses.

EK170

Due to the great differences in the stiffnesses of joints using different type of connectors, it is usual not to allow the joint force to be shared between slip and […]

EK103

The secant stiffness method requires secant flexural and axial stiffnesses to be updated with each iterative cycle of the load step. This method differs to the Newton-Raphson and modified Newton-Raphson […]

EK102

Calculation procedures for the modified Newton-Raphson method are the same as for the Newton-Raphson method, except the stiffnesses for the first cycle are held constant for each iterative cycle of […]

EK101

In a Newton-Raphson method at the start of the load step, element stiffnesses are set to the values from the end of the previous step.
