Reinforcing Steel CRSI

Most people are familiar with reinforcing steel commonly called quot rebar quot It is used in bridges buildings skyscrapers homes warehouses and foundations to increase the strength of a concrete structure Rebar is used in concrete to provide additional strength as concrete is weak in tension while steel is strong in both tension and compression

What is lap length in reinforcement bars General rules

2021 01 28 nbsp 0183 32 The maximum length of the reinforcement bars is limited to 12 2m or 40 ft This limited standard length is to facilitate the smooth manufacturing process and to avoid rebar transportation problems When we construct the multistorey buildings the length of the single bar is insufficient to reach the top building height from the footing level
