Comparison Of Two Typical Equivalent Linearization Procedures For Different Classes Of Site

We Will Adopt Ground Motion Parameters When We Conduct The Seismic Safety Assessment Of The Construction Site. The Ground Motion Parameters Include The Ground Motion Peak(The Peak Acc Eleration, The Peak VElocity, The Peak Displacement), The Response Spectrum And The Intensity Env Elope Function. Among Them, The Most Commonly Used Are Ground Motion Peak And Acc Eleration And Acc Eleration Response Spectrum.The 1-D Analysis Mod El Conducting The Seismic Analysis Of Earthquake Response Is Applied To The Ground, Soil And The Site Which Have Flat Bedrock Surfaces. The Main Current Programs Are SHAKE2000 And LSSRLI-1. The Common Points Of These Two Programs Lie In Both Of Them Are Based On The Equivalent Linearization Method To Calculate The Seismic Response Of The Soil Layer.Among Them, The LSSRLI-1 Equivalent Linearization Procedure Which Is Wid Ely Used In China At Present Origins From 1980 s And Has Some Differences In The Calculation Results Of The SHAKE2000 Which Represents The Advanced Lev El In The International. This Paper Considers SHAKE2000 As Reference And Compares The Calculation Results To Understand Their Differences And Provide Foundation For The Next Step Procedure Improvement.The Main Contents Of This Paper Are:1. Introduce The Research Status Of The Reaction Analysis Method, Introduce The Method Of Equivalent Linearization, Introduce LSSRLI-1 And SHAKE2000.2, Building Profile Mod Els,SElecting Inputing Waves And Non-Linear Curves Of Soil.3, Use The Two Program LSSRLI-1 SHAKE2000, On Four Types Of Sites And Make Comparison Of The Peak Ground Acc Eleration, The Surface Acc Eleration Response Spectrum And Soil Shear Strain Between The Two Programs.4, The Calculation Of Four Classes Of Sites Under The Condition Of Two Programs, Get The RElationship Between The Differences Of The Two Programs And Site Classification, Input Earthquake Wave, Soil Nonlinear Conditions, Discussing Applicability Of The Programs.
