To withstand tensile stresses, structural concrete members are typically designed with reinforcement. Reinforced structural concrete can incorporate various materials to provide a composite material with higher tensile and shear capacity compared to unreinforced concrete. Some specialized materials used for reinforcement include polymer microfibers and fiberglass rods. However, the term “reinforced concrete” generally refers to concrete incorporating bar reinforcement (also known as bar reinforcing steel or rebar) . In some cases, welded steel wire reinforcement, placed in specific patterns and locations within a concrete structure, may be specified for concrete reinforcement.  \nThis chapter primarily covers bar reinforcement and its installation, focusing on contract requirements and best practices for installation. It highlights the types of inspections Structure Construction (SC) staff are expected to conduct. Additional guidance can be found in Construction Manual, Section 4-52 , Construction Details – Reinforcement, and SC’s Outline of Field Construction Practices.  \n4-2 Technical Resources  \nBridge Construction Memo (BCM) 52-1 , Reinforcement – General, and its accompanying attachments provide supplemental information to the topics presented in this chapter. The attachments include rebar details such as radius, hook, and bend lengths, as well as bar reinforcement identifications. The radius and hook details in the BCM 52-1 attachments conform to the Building Code Requirements for Structural Concrete published by American Concrete Inst","cbCaibphcKTCS72m","https://ap.wps.com/l/cbCaibphcKTCS72m","pdf",4163227,44,"English","# Chapter 4: Reinforcement\n## 4-1 Introduction\n## 4-2 Technical Resources\n## 4-3 Contract Requirements and Preparation\n## 4-4 Construction\n## 4-4.01 Shipment\n## 4-4.02 Material and Fabrication Verification\n## 4-4.03 Placement\n## 4-4.04 Safety\n## 4-5 Corrosion Protection\n## 4-5.01 Epoxy-Coated Reinforcement\n## 4-5.02 Galvanized Reinforcement\n## 4-5.03 Galvanic Anodes\n## 4-6 Headed Bar Reinforcement\n## 4-7 Splices\n## 4-7.01 Splicing Methods\n## 4-7.02 Service Splices and Ultimate Butt Splices\n## 4-7.03 Sampling and Testing – Service and Ultimate Butt Splice\n## 4-8 Drill and Grout Dowels/Drill and Bond Dowels","[{\"question\":\"Why does reinforced structural concrete need reinforcement?\",\"answer\":\"Concrete is strong in compression but weak in tension.
