Abstract :
Abstract: There are several restoration methods for brick building such as embedding FRP hank and etc. but using of those have been limited for restoration of historical building because restoration must cause minimum change inappearance. We could retrofit brick building using expandable grout with pre-stressed technique but behaviors of these mortars usually have been unknown for experts. Most of these constructions were used in domes in Iran and numerous domes in historical building indicate essentiality of this research. In this research mechanical properties of expandable grout have been determinate by experiments and then dome of Qazvin mosque was modeled using ABAQUS software as major and minor modeling combination. Results show that depending on little effect of these mortar on dome form, obtained uniform pre-stressing lead to tensile and deformation reduction and finally crack decreasing that this could be effective through the earthquake.
