Wooden beams of ceilings in historical buildings in Cairo are suffering from overloads, biodeterioration, and human and environmental deterioration that is causing cracks, deflection, and twisting or broken wooden beams. Study of wooden ceiling conditions in the Ganem Albahlawan mosque in Cairo found a five broken beams and deterioration of wooden panels in the ceiling. A numerical study and specific survey of this case study was made through structural calculation for each wooden beam, and an intervention proposal. Furthermore, an experimental study is presented about use of fiber reinforcement polymers (FRB) to treat broken wooden beams. Three groups of wooden samples were used: small, medium and full-scale sample beams. The samples were evaluated by bending and testing strength, while the experiment study used many methods of treatment, changing the type of FRP or applying different methods to be calculated and suitable for the span, condition, and the load capacity of wooden beams. Results showed the ductility of wooden beams increased, to absorb loads of more ten times than before treatment; this revives the historical wooden beams so they can continue their function.
