Steel Ductibility Features
Steel is a ductile material by nature, which also has a stable behavior under load investments and has a convenient strength-to-weight ratio. Steel can accept significant deformations beyond the elastic limit without failing, so it has the capacity to allow inelastic deformations that may be required. It can be used to construct statically indeterminate structures that meet seismic design requirements. It is therefore very convenient for buildings located in areas of high seismicity. However, the intrinsic ductility of steel is not necessarily preserved in the finished structure, so care must be taken during design and construction to avoid the loss of this property. It is this property, intrinsic characteristic of structural steel , that does not exhibit any other construction material in a completely clear way, and that makes possible the application of plastic analysis to the design of structures. Not all steels meet the ductility requirements that are required in area...
