Hi All,
To date I have been using openSees to complete most of my NLTH analysis and I quite like like using this programme. However, my company have decided to go with sap2000 for future NLTH analysis projects. My question is quite general but hopefully might start a discussion. I am quite sure...
Hi All,
Can anyone out there tell me how to extract modal amplitudes for a set of nodes from Etabs 2015. I am completing a modal analysis for a slab, I can obviously see the modal amplitudes (for each node) on screen as well as all other displacements for my given load cases. However, if I go...
Hi All,
I am trying to figure out whether a seismic static lateral force analysis (or equivalent static analysis or lateral force method) gives absolute or relative storey forces. My aim is to convert the obtained floor forces (Fi) (from the static analysis) into pseudo floor accelerations...
Hi,
Has anyone been using Revit structure to build their SAP models and if so how good is it?
Is there bi-directional compatibility and what versions of each software work best?

Hi all,
I am trying to perform an Explicit direct-integration dynamic analysis.
I am simulating a single degree of freedom (SDOF) structure initially to test my method and the results.
My structure is a simple strut (cantilever column, see attached) which is fixed at its base and free at the...
Hi all,
I have an issue with convergence when modelling a steel brace member with two lines of symmetry and using shell elements (S4R).
I am trying to compare the cyclic hysteresis response of the brace to existing test data. I am using a symmetric tensile/compressive displacement controlled...
Hi,
I am performing a low cycle fatigue analysis of a strut member subjected to cyclic loading using ABAQUS/CAE.
I have all my material properties working using a combined isotropic/kinematic hardening model. My difficulty lies in implementing the life parameters detailed below:
Fatigue...
Hi,
I am trying to carry out a cyclic (tension and compression) analysis on a steel strut in Ansys WB. I am trying to obtain the force-displacement response of the strut under displacement controlled loading.
What is of primary interest is the buckling behaviour of the strut and so to model...
Does anybody know how to combine two material models in Ansys Workbench v12.
I am trying to perform a cyclic analysis and the most accurate material model to use is an isotropic/kinematic one. In particular a bilinear isotropic hardening model with a chaboche nonlinear kinematic hardening law...
