Abstract EN

In the present paper, the postcracking strength of an RC shear wall element which follows the construction practices applied in Greece during the 70s is examined by taking into account the complex geometry of the crack of the wall and the mixed friction-plastification mechanisms that develop in the vicinity of the crack.

Due to the significance of the crack geometry, a multiresolution analysis based on fractal geometry is performed, taking into account the size of the aggregates of concrete.

The materials (steel and concrete) are assumed to have elastic-plastic behaviour.

For concrete, both cracking and crushing are taken into account in an accurate manner.

On the interfaces of the crack, unilateral contact and friction conditions are assumed to hold.

For every structure corresponding to each resolution of the interface, a classical Euclidean problem is solved.

The obtained results lead to interesting conclusions concerning the influence of the simulation of the geometry of the fractal crack on the mechanical interlock between the two faces of the crack, a factor which seems to be very important to the postcracking strength of the lightly reinforced shear wall studied here.
