Hi, guys!
I need to model soil-structure interaction for a large building (approx 68x68x70 meters). I am using NIST GCR 12-917-21 "Soil-structure interaction for building structures" as a reference document. I have calculated lumped spring-dashpot coefficients for vertical translations...
Hi guys!
Currently I am involved in a benchmark project for the ICOLD (International Committee for Large Dam) for risk assessment of an embankment dam. One of the failure modes is of course sliding instability of the downstream slope. For the project a very simple approach is proposed for the...
My question is if there is anybody in the forum who participated in past GEO-SLOPE Workshops in Canada or in Europe and if they found them usable. I am GeoStudio 2012 user for about an year and a have and I am not sure if the topics are beginner- or higher level.
The structural team I work for is currently assessing a structure for tornado loading. Since most civil code have little or no information on tornadoes other than hazard maps we are using the US NRC Reg Guide 1.76 Design-Basis Tornado and Tornado Missiles for Nuclear Power Plants. Regarding the...
I am performing strength and deflections checks of an existing 150 m tall RC concrete chimney with varying cross section according to Eurocodes.
In EN1991-1-4 (Wind Loading) we can find this text:
E.1.2 Criteria for vortex shedding
(1) The effect of vortex shedding should be investigated when...
Considering the Kuhlemeyer and Lysmer criterion to transmit a maximum frequency fmax the mesh size should be L<C/(10fmax), where C is the wave velocity. My question is if I am using second-order finite elements (8-node rectangular for example)what is L - the size of the FE or the distance...
Can you recommend me a good textbook on retrofit and strengthening of earth retention walls? I need something more graphic - with examples and different design approaches rather than just calculations.
In Eurocode 3 (EN 1993) is there a procedure to calculate the reactions in lateral restraints of compressive members (columns, truss chords) or compressive flange of beams? I am currently designing a single-story industrial building and I want to use the purlins as lateral restraints of the...
Hello, everybody!
I am designing roof beams (purlins), according to Eurocode 3. I chose cold-formed U-section - 140x60x4. Should I use EN 1993-1-3 for this section, or I can use the simpler procedure in EN 1993-1-1, because the section is class 3 when calculated, according to Table 5.2 in...
I am looking for an open source/academic code which is able to calculate the frequency-dependent impedance functions for Soil-structure interaction in the case of layered soil deposit.
Thank you!
Hi, guys! I have a FE model of a frame steel structure (mezzanine for a turbine foundation), built in Staat Pro v2007. I want to use this model for calculations with SAP2000 v14 and I want to export it. Is there a smart way to do it, so I can keep as many properties as possible (frame and...
Hi, everyone! I am looking forward to start making structural design drawings (outsourcing) for projects in New Zealand. I have no expirience in the region, so I am interested in the typical pricelist for such services - detail design drawings, preliminary calculations etc. It's about...
Hi, guys! I've just started using SHAKE for calculation of wave propagation in soils. I have two questions about the syntax of the code, because I use the Fortran version and not the new SHAKE2000 (with GUI). I have the source code and it is possible, but not preferrable to make changes and...
Hello guys! I am looking forward for buying a new notebook in the middle price range (700-800 euro/900-1100 dollars). I want to use it also for solving some not very big models - both linear and non-linear models. I am thinking of some machine with 8GB RAM and i5 2-3 GHz CPU and preferring Dell...
Hi, guys! A friend of mine, who is still in the university has this very simple problem to solve with FEA:
As you see this is a rectangular wall with some uniform edge loads. The problem the girl encountered when analyzing with SAP2000 v.12 was infinitely large displacement of the bottom...
