Question
How can I enter or read out a response spectrum via the COM interface in DYNAM Pro?Answer
The COM interface allows you to read out or create a user-defined response spectrum in RFEM and RSTAB.
For the conversion, it is necessary to get the interface to the module (IDynamModule) via the interface to the RFEM model (IModel). This interface is then used to create the module case (IModuleCase). IModuleCase includes the GetRSParams function, which can be used to read out the parameters for the response spectrum. On the other hand, the SetRSParams function can write new data. The following example code clarifies it:
Dim iApp As RFEM5.ApplicationDim iMod As RFEM5.modelSet iApp = GetObject(, "RFEM5.Application")
Dim rs_no As Integerrs_no = 1
On Error GoTo e
' Checks RS-COM license and locks the application for using by COM. iApp.LockLicense
Set iMod = iApp.GetActiveModel
' get module interface Dim iDyn As IDynamModule Set iDyn = iMod.GetModule("DynamPro")
' get module case interface Dim iDynCase As IModuleCase Set iDynCase = iDyn.GetData ' set response spectra parameters Dim rspara As RSParams rspara = iDynCase.GetRSParams(rs_no) Dim rs_spec(0 To 10) As RSTableRow Dim index As Integer index = 0 rs_spec(index).s = 0.6 rs_spec(index).T = 0 index = 1 rs_spec(index).s = 1.33 rs_spec(index).T = 0.153 index = 2 rs_spec(index).s = 1.33 rs_spec(index).T = 0.4 index = 3 rs_spec(index).s = 1.204 rs_spec(index).T = 0.443 index = 4 rs_spec(index).s = 1.07 rs_spec(index).T = 0.5 index = 5 rs_spec(index).s = 0.7 rs_spec(index).T = 0.761 index = 6 rs_spec(index).s = 0.508 rs_spec(index).T = 1.051 index = 7 rs_spec(index).s = 0.367 rs_spec(index).T = 1.453 index = 8 rs_spec(index).s = 0.267 rs_spec(index).T = 1.995 index = 9 rs_spec(index).s = 0.16 rs_spec(index).T = 2.584 index = 10 rs_spec(index).s = 0.16 rs_spec(index).T = 5

First, an array of the RSTableRow type with 11 elements was created, filled with data, and then saved under the UserDefinedTable property. The transfer is carried out using the SetRSParams command.

In RFEM 5 and RSTAB 8, it is possible to assign nonlinearities to member end releases. In addition to the nonlinearities ‘Fixed if’ and ‘Partial activity’, you can also select ‘Diagram’. If you select the ‘Diagram’ option, you have to specify the according settings for the activity of the member end release. For the individual definition points, it is necessary to specify the abscissa and ordinate values (deformations or rotations and the according internal forces) that define the release.

Material Model Orthotropic Masonry 2D
The material model Orthotropic Masonry 2D is an elastoplastic model that additionally allows softening of the material, which can be different in the local x- and y-direction of a surface. The material model is suitable for (unreinforced) masonry walls with in-plane loads.
