CHARACTERISTICS AND APPLICATION OF LIGHT STEEL STRUCTURE
Comparing with traditional concrete structure , light steel structure is homogeneous , strong and with short construction period As well as , light steel struck-sure is remarkable anti-seismic and high percentage recovery ? Strength and elasticity modulus of steel is several times higher than bricks , so steel structure is light mass under the condition of same load On damage side , ht steel structure has e omen of deformation and belongs Ductile fracture structure , which can identify risks , so that it can avoid risks.
Steel structure has following advantages : light weight , convenient , economic hot construction period , large span , durable structure , building new aesthetic etc Light steel structure mainly apply on large span factory , warehouse cooling storage , high-rise building ,office building multi-storey car park and residence.
LIGHT STEEL STRUCTURE PERFORMANCE
1. Material is high strength and light weight
Both steel strength and elasticity modulus are high And comparing with concrete and wood , the ration between steel density and its yield strength is low , so steel structure has small component section and light weight under same stress condition , which can apply on large-span , high , weight structure.
2 .Steel is good toughness , ? good ? plasticity homogenous and its structure is safe
Light steel structure can withstand the impact and dynamic loading and has good anti-seismic function.Steel internal organization structure is on average and is similar to isotropic plasmids . Steel structure is work well on theory of computation in practice.
3 Light steel structure has high mechanization degree on production and installation
Light steel structural member is convenient to product and assemble Mechanization makes high precision steel structural member , high efficiency production , high speech assembly and short construction period . Light steel structure is a structure with highest industrialization degree.
4 Light steel structure has well seal function
Welding structure can be sealed completely , so it can be such structure with good air tightness and water tightness as high pressure vessel , large oil pool and pressure piping.
5 light steel structure is heat-proof but not fire-proof.
Steel property just change little bit under 150 so light steel structure can apply on hot procedure workshop On the contrary , structure need to be protected by heat insulation board when its face suffers 150 C heat ? radiation . Steel strength and its elasticity modulus go down obviously in 300 c-400 C Steel strength tent to be zero in about 600 C . In a building with special fire roof requirement steel structure must to use fire-proof materials for upgrade fire-proof level.
Steel strength just change a few when surface temperature is under 150 C , so light steel structure can apply on hot procedure workshop Steel strength tent to zero in 500 c-600 C . Therefore , steel structure will collapse suddenly in fire disaster for s fire-proof time is short . In a building with special fire proof requirement , steel structure must to use fire-proof materials.
7 . low-carbon , energy saving , environmental and recycle.
Construction rubbish almost will not emerged in dismantlement of steel structure .And steel can be recycled.
