Analysis and assessment of seismic drift of reinforced concrete mixed (shear wall-frame) structures

Deprem yüküne maraz perdeli-çerçeveli bir yapının yatay ötelenmesini belirlemek için analitik bir metot önerilmektedir. Analitik metodun geçerliliği farklı yükseklikteki üç boyutlu binalar üzerinde test edilmiştir. Analitik metot ile bulunan yatay ötelenme değerleri bilgisayar ile bulunan değerlere çok yakındır. Önerilen analitik metodun yüksek deprem riskli bölgelerdeki perdeli-çerçeveli yapılara uygulaması üzerinde durulmuştur. Önerilen analitik metotla hangi binanın depreme karşı dayanıksız olduğu ve güçlendirilmesi gerektiği de kolayca tespit edilebilmektedir.

Betonarme karma (perdeli-çerçeveli) yapılarda sismik kat ötelenmesinin analizi ve değerlendirilmesi

An analytical method is proposed to determine the sway of a mixed structure (frame + shear wall) subject to seismic forces. The validity of the analytical method is tested on 3-D buildings of different heights. The sway results obtained by the analytical method and computer agree well. The implementation of the proposed analytical method to shear wall - frame buildings in regions of high seismic risk is emphasized. The determination of which building is earthquake prone and should be strengthened can easily be done by the analytical method proposed.
