Response of RC panels accounting for crack development and its interaction with rebars

Miguel Fernández Ruiz, Eckart Hars, Filip Niketic

The response of reinforced concrete (RC) elements subjected to in-plane shear and axial stresses is governed by various potential failure mechanisms. For structural panels subjected to uniform stress states, their ultimate strength can be governed by yield ...

Experimental investigation on the load-carrying capacity of thin webs including post-tensioning tendons

Aurelio Muttoni, Miguel Fernández Ruiz, Eckart Hars

The presence of post-tensioning tendons in webs decreases the load-carrying capacity of the compression struts that are necessary to transfer shear forces. This effect has been known for a long time, but was initially not included in design codes. In parti ...

Effect of Duct Type on the Shear Strength of Thin Webs

Aurelio Muttoni, Olivier Burdet, Eckart Hars

A series of 16 specimens of concrete web panels 23.6 x 23.6 x 4.9 in. (600 x 600 x 125 mm) was tested in compression to investigate the effect of the presence of various types of post-tensioning ducts on the strength of the shear-induced compression struts ...

Zum Querkraftwiderstand von Stahl- und Spannbetonträgern mit dünnen Stegen

Eckart Hars

The design of reinforced and prestressed concrete girders is usually performed so as to avoid any non ductile failure mode. Amongst these failure modes, one of the most undesirable occurs by crushing of concrete in the web. To avoid this brittle type of fa ...
