Background
At present, on building structures with higher requirements on earthquake resistance, such as nuclear power building fields, tie bars are usually arranged between main bars to enhance the earthquake resistance of buildings.
The installation mode of lacing wire has three kinds: the tie bar is close to the hoop and hooks the longitudinal main bar, the tie bar is close to the longitudinal main bar and hooks the hoop, and the tie bar hooks the longitudinal main bar and the hoop at the same time. The 16G101 atlas specifies that in an earthquake-resistant structure, for a lacing wire with a diameter d, the bending length is 10d or 75mm whichever is greater. In the field of nuclear power buildings, main reinforcements are generally 40-specification, the spacing is 200mm, lacing wires are 16/18/20/22/25-specification, and if 25-specification lacing wires are adopted, the bending length is 250mm.
