Characteristics of Steel Structures

 


1、 Lightweight and high-strength


Q235 steel density: 7850kg/m ³


Strength: 215N/m ²


C30 concrete density: 2450kg/m ³


Strength: 14.3N/m2


Lightweight - the ratio of mass density to strength of a material ρ/ F small


Q235 steel ρ/ F=1.7-3.7x10-4/m


C30 concrete ρ/ F=17x10-4/m


2、 Good plasticity and durability


Reflection on the Wenchuan earthquake damage: Steel structure buildings have good ductility and strong integrity, excellent seismic performance, and rarely experience overall damage or collapse during earthquakes.


3、 Convenient manufacturing and short construction cycle


Prefabrication of components in the factory, with short construction cycle


4、 Good heat resistance, poor fire resistance


5、 Poor corrosion resistance


6、 Low temperature cold brittleness tendency
