Unfortunately, SeismoStruct does not support inclined bars at the beam edges. The best thing to do is to employ hard calculations for the estimation of their contribution in the shear capacity.

Re: Diaphragm
You can define semi-rigid diaphragms either with the shell4 element or with the rigid diaphragm with reduced stiffness coefficients (see Program Settings).

Re: Shear capacity calculation problem
The shear capacity is determined by several other factors, apart from the geometry and the transverse reinforcement, e.g. the axial loads, the ductility demand, the Lv=M/V ratio, and the longitudinal reinforcement. In particular for the Greek code, see equation (G.1) in Annex 7G. This is the ...

Re: How are Average Misfit and Max Misfit calculated in SeismoMatch?
The maximum misfit is the maximum difference of the spectral values between the target spectrum and the response spectrum of the derived accelerogram inside the period range that has been specified by the user. The average misfit is the average of all the differences in the specified period range ...

Re: Cracked/Uncracked stiffness for Pushover
You may use the displacement-based plastic hinge model for a linear M-theta diagram. (Main Window>Analysis Parameters>Advanced Settings>Advanced Building Modelling)
The default setting for the frame elements is with fiber-modelling.

Re: Cracked/Uncracked stiffness for Pushover
Section 7.2.3 of KANEPE refers to the elastic methods of analysis. In the Nonlinear Static Procedures the uncracked stiffness should be employed, in the execution of both eigenvalue and pushover analysis. Specifically, in pushover the analysis starts with the uncracked/undamaged members and the ...

Re: Estimating Tp for records with pulse period larger than 4
No, there are no constraints in the pulse identification algorithm of SeismoSignal.
In some cases, there are inconsistencies between the NGA database parameters and the SeismoSignal calculations with records that are NOT pulse-like. In these cases, since the algorithm employed is different ...

Re: Changing Damping does not change
Where exactly does this happen? In which code, specifically? We checked it and the spectrum changes, when the user changes the damping value.

Re: First Mode Period of Steel MRF
The wizard create a sample model that is not necessarily correct technically, for instance in steel buildings there are no steel braces (which is the main reason for the very large fundamental period). It is just a way to introduce the program quickly to new users.

Re: Modeling of Friction Pendulum in Seismobuild Advanced
Can you be more specific? What do you mean with "the parameters (of the Friction Pendulum isolators) that can be entered in the modeling window, are derived directly from the one for elastomeric isolators"?
If you mean that the two types of isolators have the same input, this is not correct. The ...
