Abstract:
To examine the behavior of rigid plastic structure several methods have been employed, one of
which is the linear complementarity approach. However, numerical model of linear
complementarity problems (LCP) under small displacement subjected to extreme dynamic loading
model can further be refined to predict exact response of structures. In the current study, a
numerical model has been established by incorporating large displacement along with the strain
rate effect by taking into account the nonlinearity of geometry due to axial forces in an RCC beam
in order to obtain precise and more accurate response of structures subjected to impact loading.
The maximum mid span deflection obtained from the proposed model under impact loading is
statistically compared to the experimental dataset of tested RC beams carried out in various
researches available in the literature. Furthermore, the model is then tested through
experimentation work under impact testing by constructing an assembly of impact loading and
Drop Hammer. A parametric study is conducted by varying the drop height of hammer and
thereafter the results of mid span deflections obtained from experimental work are compared with
those obtained from the proposed model to ensure the efficiency and reliability of the model
