Change in modal parameters of cracked single-edge notched plain concrete Beams

[EN]The aim of this work is looking into the possibility of capturing the change in the modal properties (natural frequencies, modal shapes and modal damping ratio) of plain concrete elements due to the presence of cracked areas by using a simple continuum damage zone numerical model.

Impedance functions of end-bearing inclined piles.

[EN]In this work, stiffness and damping functions of pile foundations with inclined end-bearing piles have been computed for square 2X2 and 3X3 pile groups embedded in a soft stratum overlaying a rigid bedrock. The paper algo invetigates the influence that the assumption of a perfectly rigid bedrock and fixed boundary conditions at the pile tips have on the impedance functions.
