An OVERVIEW on EARTHQUAKE LOAD REDUCTION FACTOR of REINFORCED CONCRETE BUILDINGS

Abstract

In this paper, analytical study has been performed to determine earthquake load reduction factor of reinforced concrete (RC) buildings, to investigate parameters affected to earthquake load reduction factor and their influence values. 48 RC residence buildings have been modelled according to the TEC-2007 criteria and then static pushover analyses have applied to these buildings. After analyses, lateral load- lateral displacement curves have been obtained for each building. Using load-displacement curves, overstrength factor which is a parameter of load reduction factor has been calculated. The obtained values have been compared with TEC-2007 values for releated building types and the results have been interpreted. According to the obtained values from the study, a new point of view has been developed for TEC-2007.

BETONARME BYNALARIN DEPREM YÜKÜ AZALTMA KATSAYISI ÜZERYNE YENY BYR BAKI?

Öz

Bu çaly?mada betonarme yapylaryn deprem yükü azaltma katsayylarynyn tespiti, deprem yükü azaltma katsayylarynyn ba?ly bulundu?u parametreler ve etki de?erleri için analitik bir çaly?ma yapylmy?tyr. Çaly?mada konut türü 48 adet betonarme bina TDY-2007 normlaryna göre modellenerek statik itme analizine tabi tutulmu?tur. Statik itme analizi neticesinde yapylaryn her biri için yük deplasman e?rileri elde edilmi?tir. Yük deplasman e?rilerinden, her bir yapy için deprem yükü azaltma katsayysynyn bir parametresi olan dayanym fazlalyly?y katsayylary elde edilmi?tir. Elde edilen verilerle TDY-2007'de yer alan ilgili yapy türü için tanymlanan deprem yükü azaltma katsayylary kar?yla?tyrylarak sonuçlar yorumlanmy?tyr. Mevcut verilere göre deprem yükü azaltma katsayysynyn tanymlanmasyna yönelik yeni bir baky? açysy geli?tirilmi?tir.
