Abstract:
In understanding the dynamic behaviour of many structures where analytical modelling
does not suffice and in the development of the codal provisions, experimental testing has
remain the common thing to rely on. Many experimental testing procedures have been
developed in the past and is still being updated based on the requirement of the testing.
Pseudodynamic testing procedure is one of the many testing methods for large scale testing
which has the simplicity of quasi-static testing and the reliability of the shake table testing
method. Here, various testing methods has been described and then the development of
pseudodynamic testing method is presented. The testing procedure, numerical techniques
and the error in the testing method is discussed further. For the development of this testing
facility in pseudodynamic laboratory at IIT Roorkee, this study is done. For the analytical
simulation of pseudodynamic testing, a code is developed which updates the stiffness of
the non-linear member during dynamic analysis. The code is verified with a solved example
and then is used for the analytical simulation of a steel cantilever column as a SDOF
system. The simulation is done for three different earthquakes and the results are presented
thereafter
