Abstract
The Strength Capacity of Confined Masonry Column is One of the Topics that Need to Be Studied. in This Study, the Efficiency of using Different Types of Advanced Composite (Non-Corrosive Materials) Such as Fiber Reinforced Polymer (FRP), Fiber Reinforced Cementitious Matrix (FRCM), or Steel Reinforced Grout (SRG) in Confining Masonry Columns is Investigated. a Wide Range of Experimental Database of Masonry Column Specimens Has Been Collected from the Results that Available in Scientific Literatures. Different Theoretical Standards and Proposed Models that Used to Predict the Capacity of Masonry Columns Confined with FRP and FRCM Are Evaluated based on Collected Experimental Database. Since There is No Standard Code or Specific Proposed Model for SRG System, the Confined Capacity of This System is Predicted and Evaluated using the FRCM Proposed Models. the Justification of using These Models is that Both FRCM and SRG Systems Have the Same Concept of using Inorganic Material as a Paste Material. an Index Named "Equivalent Fiber Reinforcement Index (EFRI)" is Proposed to Capture the Key Factors that Control the Behavior of the Confined Masonry Columns with Different Advanced Composite. This Index is Used as Reference Parameter for the Purpose of the Comparison between Different Strengthening Systems. as a Result, All Types of Advanced Composite Presented a Significant Increase in Ultimate Capacity. Also, the Behavior of the Masonry Columns Was Significantly Dependent on the Type of Fabric Used. Different Modes of Failure Were Reported, Including Crushing of Masonry Block, as Well as a Deboning of FRP from the Masonry Substrate and Deboning or Slippage of Fabric within Inorganic Paste Matrix. Compared with Other Models and Standards, the American Concrete Institute Committee 440 (ACI 440) and American Concrete Institute Committee 549 (ACI 549) Shows Very Good Predictions for the Confined Capacity of Masonry Columns Strengthened by FRP and FRCM or SRG Respectively.
