Abstract
Background: Many historical and archaeological masonry structures located in seismically moderate and active areas are not capable of sustaining seismic and dynamic actions. Furthermore, recent earthquakes in urban areas like Cairo, Egypt have clearly demonstrated an urgency to upgrade and strengthen these deficient historic masonry structures. Retrofitting with CFRP is now extensively being used as a seismic retrofitting method all over the world. It increases the load bearing capacity of structural elements like beams, slabs, walls and columns; Improve the seismic ductility of masonry stone and brick columns and piers; Improve the seismic response of concrete beam-column connections, shear walls and collector elements; Improve the seismic performance of masonry shear walls and in-fill walls; Restore structural capacity to damaged or deteriorated historic and modern concrete structures.
Objective: The aim of the present research is to investigate the application and durability of historical circular masonry stone columns completely strengthened by carbon fiber reinforced polymer (CFRP) laminates. This paper presents a comprehensive review with complete project experimental and implementation of CFRP in strengthening and seismic retrofitting of eight internal circular masonry stone supporting columns in the Saint George church in old Cairo area in Egypt and other important monuments in Cairo.
Results and Conclusion: Strengthening and seismic retrofit with CFRP materials has gained notable acceptance from the archaeological structural restoration communities in recent years. CFRP is characterized with high strength to weight ratio, excellent resistance to creep and fatigue, extremely durable and low aesthetic impact. Its benefits include the add strength without adding dead load, Withstands sustained and cyclic load conditions, extremely resistant to wide range of environmental conditions, and easy to conceal.
