海外项目系列(Ⅱ)：美标模块之抗震参数篇

海外项目系列（Ⅱ）：美标模块之抗震参数篇(1)彭志丰随着“一带一路”的深入发展，中国设计师参与海外项目日益增多；随着新冠的有效控制，海外项目脚步逐步加快；为了使中国设计师能够快速胜任海外项目的设计，近期将结合盈建科欧美模块推出海外项目设计系列知识期刊。盈建科欧美模块支持中文和英文两种语言，语言可以自由切换。海外项目在某些设计理念与国内设计存在明显差别，第二期为“美标模块之抗震参数篇”，分为四部分，主要介绍美标模块抗震参数和某工程案例地震参数选取，以便用户快速掌握美标地震参数意义和确定流程。由于笔者英语水平有限，以免翻译错误，误导读者，本篇也将美标条文详细呈现，以便读者查阅。YJKCAD-Input Parameters-Earthquake Information Earthquake InformationGeneralEarthquake Information Earthquake InformationControl Info.of Calculat.Seismic Design CategoryDamping Ratio of the Structure(%)Control ParametersBudkding AnalysisSeismic CoeffidentsParameters of Eigenvalue AnalysisWind Load Information0.2 Sec Spectral Accel.Ss0.5Basic ParametersConvertType of AnalysisWYD-RITZCustom Wind Load1 Sec Spectral Accel.S10.2L6C97OCustom Number of Vibration Modes15Earthquake InformationAuto Generate Number of Vibration ModesEarthquake InformationLong-Period Transition Period TLCustom Factor CurveSum of Modal Participating0Ampification FactorSite ClassMass Ratio(%)Design Information150Site Coefficient.Fa1.2Maximum Number of VibrationComponent Design Info.Component Design Info.Site Coeffident.Fv1.6Accidental EccentricityEnvelope DesignConsider Accidental EccentricityMaterial InformationCaloulated CoefficentsX Direction 0.05YDirection 0.05Material ParameterssDs=(2/3)℉asg0,4Caloulation Method:Steel Bar StrengthBasement InformationD1=(2/3)午v*s10.213333Equivalent Torque Method (Traditional)Load CombinationRayleigh-Ritz Me thod (New)Combination FactorsFactorsTable of CombinationResponse Modfication.R6Consider Bi-directional Earthquake ActionCustom Load Case CombO5R55○1"+0.3Overst女engt.Omega02.5Deflection Amplification.Cd5.5oaennrocod9Occupancy Importance.I1口t3S8Redundancy factor,Rou1.3ento6sCombination Coefficient for Variable0.5ActionDuctiity Classs of Shear WallsSpecialUpper Limit Factor of PeriodDuctiity Classs of Concrete FramesIntermeFactor ofCt0.0488Factor of x0.75Ductiity Classs of Steel FramesOrdinaryImport ExportOKCancel图1.K美标模块英文地震参数设置页
