| Abstract | ||
| The behavior of thin composite elements using various kinds of reinforcement meshes was investigated by conducting flexural tests on simply supported twenty four cases of composite, with three identical specimens of each case, under two symmetrical point loads. The parameters of this study include: the effect of the various kinds of reinforcement meshes (stainless steel meshes and E-fiberglass meshes), number of mesh layers and various mesh diameters with opening size, as well as various kinds of mortar materials as matrix (cement grout mortar and polymer-cement grout mortar) on the first crack load, bending stiffness, ultimate flexural load, load-deflection behavior, crack characteristics, energy absorption capacity and ductility index. The results indicate that the use of stainless steel meshes as reinforcement system in the composite elements has a significant contribution to the improvement of bending performance of thin composite elements than that of using fiberglass meshes, as well as, increasing the number of mesh layers has an appreciable effect too. While, for the same number of mesh layers, using the various diameters with opening size of stainless steel meshes has a relatively small favorable effect. However, using the various mortar materials as matrix, behaves very similarly. The method outlined by ACI Building Code is used to compute ultimate moment capacities. The results obtained using this method is compared with the experimental results. | ||
