connector

Hello All,

I am trying to build a homogenized model of beam elements and 2D solid elements in abaqus 6.12. I tried connecting beam elements with plane stress elements through sharing (common) nodes with basic interaction module. The node of beam element (lower end) and node of solid element (upper) are connected through a wire offered in interaction module. This wire have been assigned connector properties. I tried to connect with axial (translation) + rotation connector, so the bending of beam can be transferred to solid elements. But I did not get expected behavior.

<p>Hi everyone. I want to model the fasteners connecting a wood sheathing to a steel frame in Abaqus. I want to input the same force-displacement behavior for all translational directions in the plane of the sheathing (like a radial spring). <br /> <br /> I was using spring element type Spring2 (nonlinear) but I could define behavior in only 2 translational directions in the sheathing plane (X and Z). This made my model overly stiff after the elastic range. I read about the RADIAL-THRUST connector element but it does not seem to be the one.

Very urgent two enquires:

1. How to model rotational spring element in order to define a curve
like M=k*(theta) where theta is the rotaional angle? It seems that
abaqus could only provide F=kx model.

2. there is a dashpot connector element which behaves like F=C * V
(where C is a constant), can I ask how to model F=C*(dv/dt)=C*a(where a
is the derivative of change of velocity)?

Thanks.
