Non-linear shear model for R/C piers
The work presented has been developed within the Prenormative Research in support of EuroCode 8 (PREC8) programme of the European Commission. The EuroCode 8 (EC8) are the provisional European standards for the design of civil engineering structures in seismic prone areas. This programme included experimental test on a series of bridge structures that have been tested under Pseudo-Dynamic conditions.
Experimental tests were carried out to study the behaviour of bridge piers under cyclic loading. The results from these tests underlined the need to improve an existing fiber model to represent the non-linear behaviour of structures where the influence of the shear forces is not negligible. Thus, a strut-and-tie formulation coupled with the classic fibre model for flexural forces was developed. This formulation is based on the analogy of a R/C structure damaged with diagonal cracking with a truss made of concrete diagonals and steel ties.
The model is applied to a set of bridge piers tested at the ELSA laboratory and the results are compared with the experimental response.
