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 ...
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 ...
La résistance à l’effort tranchant d’une poutre précontrainte dépend d’une part de la résistance effective à la compression de l’âme et d’autre part de la reprise d’effort tranchant par les câbles de précontrainte inclinés et probablement par l’aile compri ...
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 ...
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 ...
