Analysis Of Seismic Response Of HSLC High Speed Railway Building Structure

High-strength lightweight concrete (HSLC) is both structural and functionalcharacteristics material, with high strength and light weight, thermal insulationperformance.energy-saving effect is remarkable, crack effect is obvious, high durability, highfire resistance,low cost of project.HSLC has a good prospects of the green buildingmaterials.The U.S., Germany, Japan, Norway and other countries used HSLC widely inhigh-rise buildings, public buildings, marine engineering, bridge engineering and other fields.In recent years, as Chinese high-speed railway booming developed,a large number ofhigh-speed railway station house begin construction,using this energy-saving, environmentalprotection, high efficiency, green building materials in high-speed rail building structure, toachieve high-speed rail station house structure of technological innovation, energy saving isimportant. In this paper,study the high-speed railway stations, carried out the elastic andinelastic seismic response analysis. Provides a theoretical basis of HSLC material using inpublic buildings.In this thesis, we analyzed the different responses under7degree earthquake betweenHSLC and traditional concrete railway building structure:(1) Designed the structure ofHSLC railway building and traditional concrete building, due to the material’s character oflight weight, compared with ordinary concrete materials, HSCL structure can significantlyreduce the dead load proportion, reduce structural forces, HSLC has a good potential in largespan structural.(2) By modal and spectrum response analysis, the period of LC40lightweight concrete structure is greater than C40ordinary concrete structures, base reactionsand member forces are smaller, however, the structural layer displacement becomes greater.Suffice the requirements of the code for seismic design of buildings.(3) Conducted thedynamic nonlinear time history analysis,Studied the HSLC high-speed rail station’s reactionunder the action of seismic waves at different peak acceleration, the different spectralcharacteristics, analysis the substrate reaction force, vertex displacement, story drift, driftangle and part of the member forces. Indicated that the structure suffice "no collapsing withstrong earthquake", we can conclude that HSLC structure has a good seismic performance.
