Re: UHPC (Ultra-High Performance Concrete) model
Dear Roshen, dear Amr Masoud, Personally, it is not clear to me why a new constitutive model would need to be implemented in SeismoStruct in order to be able to analyse structures with UHPC. Indeed, I would immagine that, by appropriately setting the parameters of one of the already implemented mate...

Re: Viscoelastic damper curve type
Hi Ali, I carried out a search on the term "Kelvin" in SeismoStruct User Manual and Help System, and found the following: The dashpt element may be employed whenever the need arises for the introduction of a Maxwell model (i.e. series coupling of damping and stiffness), by placing in serie...

Re: How to calculate maximum base shear capacities Hmax2 and Hmax3 and maximum base moment capacities Mmax2, Mmax3, Tmax
Sukalyan,
If you download this report and search "Hmax" and "Mmax", you should be able to find some useful guidance.

Re: How to simulate the soil-structure interaction
Hi langxuzeng, There are a number of publications that describe how to estimate soil damping coefficients (which can be used to represent both radiation and material/hysteretic damping). The two that come more quickly to my mind are: - Gazetas, G. [1991] “Foundation vibrations,” Foundation Engineeri...

Re: Viscoelastic damper curve type
Dear ali_hssn, While there is indeed not a dedicated viscoeleastic damper element in SeismoStruct's elements library, can you not follow one of the two following alternative modelling strategies: - introduce link+dashpot elements in parallel in order to directly reproduce the velocity-dependent beha...

Re: Fluid Viscous Dampers internal force
Personally, I tend to avoid the inclusion of equivalent viscous damping in my models, which has been extensively shown to be problematic and to potentially lead to important underestimation of the response of structures, especially when these are pushed highly into the nonlinear range. There is real...

Re: Post Tension Rocking Wall
Hi Kirkaguel, There are many ways in which post-tensioned rocking walls may be modelled in Finite Element programs, either using nonlinear spring/link elements alone or through a combination of nonlinear frame/shell elements plus nonlinear springs/links. As an example, I can point you to Chapter 2 o...

Re: Damping Recommendation from ATC 72
Kirkaguel, Just a quick note to support the (always wise) comments of huffte; there is no such thing as A correct or superior equivalent viscous damping model option. Indeed, if you do a thorough literature review on the subject, you will quickly realise that over the past 20 years many different pr...

Re: How to model waffle slabs.
Peit, This response probably comes too late, but let me in any case suggest the work of A. Benavent on modelling of waffle slabs in seismic regions (including comparisons with experimental tests). You may find his papers by e.g. carring out a search in Google Scholar (using "Benavent waffle sla...
