Abstract AR
تقدم الكودات العالمية معادلات وضعية لحساب زمن الذبذبة الأساسية للمنشآت متعددة الطوابق بنظام الإطارات الخرسانية المسلحة.
القيمة الناتجة لزمن الذبذبة الأساسية من هذه المعادلات تختلف في كثير من الأحيان عن القيمة الفعلية و ذلك لإهمال هذه المعادلات لعوامل هامة تؤثر في زمن الذبذبة.
في هذا البحث تم عمل تحليل لتسجيلات محطة خدمات الهندسية الزلزالية و المثبت أجهزتها في مجموعة المنشآت القائمة و المستخدم فيها نظام الإطارات الخرسانية المسلحة.
هذه المنشآت متعددة الطوابق و مقامة على تربة تأسيس مختلفة الخواص.
تم استنتاج معادلات وضعية لحساب زمن الذبذبة الأساسية لهذا النوع من المنشآت مع الأخذ في الاعتبار نوعية الرتبة و أبعاد المنشأ في المسقط الأفقي.
Abstract EN
At the present time most current building codes specify equations to be used for the calculation of the base shear and lateral loads.
For the determination of these lateral loads, it is necessary to determine first the period of vibration of the building.
As is known, the period of vibration of buildings can be determined theoretically or experimentally.
The theoretical design values of the period of vibration are different from the experimental ones.
Significant differences have been observed for RC multistory frame buildings and in a lesser degree for other building types such as: masonry, stone, large-paneled, and large-beams buildings.
The natural periods of vibration of 53 multistory RC frame buildings have been measured by the station of Engineering-Seismometeric Services (ESS).
These 53 buildings have different number of stories, different dimensions in plan (with different plan length to width ratios) and erected on different soil conditions.
On the basis of these data an improved simple empirical equation relating the period of vibration and the number of stories of the building is proposed to estimate the fundamental period of vibration of RC multistory frame buildings.
In this paper the effect of soil condition and the dimensions of the building in plan on the period of vibration have been studied. Comparison of periods determined using the proposed relationships and the adopted ones shows rather well agreement.
