Building Structure

Performance index

1、Strength 

The strength index of steel consists of elastic limit as σe, yield limit as σy and tensile limit as σu. In design, steel bases on yield strength which is designed to reduce steel weight to save amount of steel and construction cost. Yield limit as σy refers to the maximum stress the steel can sustain before being damaged. Meanwhile, the structure might lose it basic function because of plastic deformation. Even though the deformation changes significantly, the steel can be collapsed which can meet the requirement for anti seismic function.

2、Plasticity 

The plasticity of the steel refers to property the steel has that can be plastically deformed but not be ruptured after stress valve passes limit of yield. The main index to measure steel deformation are extensibility as δ and reduction of area as ψ.

3、Behavior of cold bending 

Cold bending behavior measures resistant ability to crack created as plastically deformed when being process under the normal temperature. Cold bending behavior is to test bend and deformity of steel when being under given bend degree in the cold and bend experiment.

4、Impact toughness 

Impact toughness refers to an ability steel has to absorb the mechanical kinetic power during the process of rupture under effect of impact load. It also is a mechanical capacity that measures the steel’s ability to resist impact load and to see if it lead to the brittle rupture because of low temperature and intensive stress.

5、Welding performance 

Welding performance refers to a property that can be able to have a good performance of wielding joint under the given wielding process. Welding performance can be divided into welding performance in welding process and welding performance in usability. Welding performance in welding process refers to sensibility to which there is no hot crack and Cooling shrinkage crack on the welding line or metal arranged around the lines. Good welding performance can ensure that there is no trace of crack on the welding metal and its adjacent base metal under the given welding process. Welding performance in usability refers to ductility in the impact toughness and thermal affect area within welding lines and mechanical property of steel within impact toughness and thermal affect area Is no less than that of base metal.
