تم في هذا البحث مناقشة معايير الاختيار و التقييس لسجلات زمنية حقيقية لتوافق كود
التصميم السوري. تم استخدام اجراءات التقييس في مجال الزمن و مجال التردد لتقييس
عدد من السجلات الحقيقية المتوفرة لتلائم طيف الاستجابة السوري. تم تحري و مقارنة
السجلات الزمنية الناتجة من ناحية مناسبتها كمدخل للتحليل بالسجل الزمني لحالات أبنية
قائمة.
In this study, basic methodologies and procedures for generation
synthetic time histories in time domain and frequency domain are
summarized. These synthetic time histories are matching Syrian
spectrum and compatible with wide range of buildings models and
soil types according to the seismic parameters of Lattakia city. This
paper will discuss the Selection and scaling criteria of three real
time history records available in strong ground motion databases to
satisfy the Syrian spectrum, and the suitability as input to time
history analysis of civil engineering structures.
