Abstract:

The applicability of the Shear-Friction Theory to Ferro cement push-off test specimen panels based on the following theoretical models such as; the applicability of the proposed empirical equation of the author, The American Concrete Institute Building Code 318-83 of Section 11.7, Pre-stressed Concrete Institute Shear- Friction Theory, Bikerland and Bikerland Shear-Friction Hypothesis and the Modified Compression-Field Theory has been investigated. The Ferro ement push-off test specimen panels of different water-cement ratio and different wire mesh reinforcement content have been cured for fourteen (14) days and were tested at twenty eight (28) and fourteen (14) days under monolithic loading to failure using Universal testing machine. The failure of the Ferro cement shear plane is characterized by yielding of the wire mesh reinforcement crossing the shear plane and by slip along the parallel crack surface.
