Abstract


The main objective of the current researches is estimating the structure performance of ferrocement domes reinforced with composite material. The current paper presented an experimental program included casting and testing up to failure four ferrocement domes. All specimens have 1000mm diameter and 500mm height; respectively and they were reinforced with welded wire meshes (for the first and second dome), fiberglass meshes (for the third dome) and polyethylene wire meshes (for the fourth dome). The second dome is the same as the first dome except that the second dome has two opening with 100x100mm dimensions to indicate the effect of the opening in the structure behavior of ferrocement dome. Also FE simulations for all tested domes were employed. The results of the experimental program indicated that the dome reinforced with fiberglass mesh has the highest service load and ultimate load and the dome reinforced with welded wire meshes achieved highest ductility ratio and energy absorption. Additionally comparing the results of FE simulations with the experimental results showed that the results of FE simulation is closed the experimental results.
