About on Low-Alloy Coupled Steel Bars Concretes Rigidity and Crack Opening Model Formula Establishment
Coupled steel bars have already more than 30 year historical development. But, it was made by HPB235, Plasticity and ductility were very poor, so, only use in planking component. Now, we made coupled steel bars by Low-alloy steels. According to tentative data, model building formula that’s rigidity and crack Opening. Provide the basis for the project construction.
