There are three types of analysis right
-linear static
-non-linear static analysis
-linear dynamic

Elastic analysis is considered as what???
Is there such thing as non linear dynamic???
Finite Element?? Response Spectrum? What category do they belong???
Working Stress Design and Ultimate Strength is applicable to all to types of analysis???
Could you use Finite element analysis with USD analysis??
then there's geometrically non-linear analysis and material non-linear analysis??

Are these used to determine frame reactions??


RE: Im lost pls help me

It looks as though you have been reading the headings from a number of books so that what is called one thing one place has a different name in another book. You are trying to start at the end, go back to the beginning and learn statically determinate analysis and grow on from there.

You are combining a lot of different and not necessarily related topics.

There are 4 types of lateral analysis that is typically done.

Linear Static- Typically this is the pseudo lateral force procedure in the building codes. Essentially you assume that the lateral behavior of the structure is governed by the first mode and assign an equivalent loading pattern that is consistent with this mode shape. This is typically an inverted triangular load.

Linear Dynamic- This would either be a response spectrum analysis or a linear time history analysis. Both of these would take into account the effect of multiple building modes to better represent the actual dynamic behavior.

Nonlinear Static - This is typically a "pushover analysis". In this approach you take into account nonlinearity of yielding elements by creating load deformation curves. You then create a force deformation curve for the entire structure by slowly incrementing the force or displacement at a target node. Once you have this curve developed you can then try and estimate the buildings actual expected displacement to see where you fall on this curve and use those results to determine the deformations in the members / joints and to check if they are within accepted limits.

Nonlinear Dynamic - This is a time history analysis that takes into account the nonlinearity of the yielding elements.
