TR. 27.4 Multilinear Spring Support Specification When soil is modeled as spring supports, the varying resistance it offers to external loads can be modeled using this facility, such as when its behavior in tension differs from its behavior in compression.

The Create Support dialog opens to the Multilinear Spring tab. In the table, type the Spring Stiffness constant which corresponds to a Displacement. These should be in order starting with the minimum displacement (e.g., this may also be the largest negative displacement) to the …

Jun 27, 2017 · I've question regarding multilinear spring supports, in order to assign the spring support I have to enter the displacement and spring stiffness values. The displacement values to be entered are actual displacements or proportional/relative to maximum displacement? In STAAD help following is defined; UNIT … MULTILINEAR SPRINGS

Feb 01, 2010 · You can accomplish your goal by using a FIXED BUT support with a very low initial spring constant in the X and Z directions, and then layer on a MULTILINEAR SPRING support which will have that same low spring constant through the 6 mm delta, and then an appropriate spring constant to represent the stiffness that will be experienced when the "bolts" reach the end of the "slots".

Multi Linear Spring (allows the user to model the support type for which the resistance offered to external loads varies with the extent of deformation of the support node)

You may use the multilinear springs which allows one to specify different spring stiffness values corresponding to the support displacements. So one can specify the value for spring stiffness as 1200 K/in for all negative displacements ( support in compression ) and specify spring stiffness as 800 K/in for all positive displacements ( support in tension ).

The multilinear spring is considered at the middle support. Now under this UDL , tension should develop at this spring , but the stiffness being zero for tension there is no reaction and it simply behaves as a beam just supported at both ends.

I am working on a method to use STAAD for lateral pile analysis using multilinear soil springs. I have written a spreadsheet to create the py curves and spring constants for a pile in sand (I am using API RP-2A method). The STAAD model is working and seems to be creating reasonable results.
