It is observed from the results that the reinforced concrete walls having large cross-sections have greater torsional strengths and torsional stiffnesses. As a result of the study cracking and maximum torsional moments, torque-twist angle curves, torsional stiffnesses, energy consumptions, damage patterns of the reinforced concrete walls have been obtained. Moreover, it has been aimed to investigate the effects of the aspect ratio on torsional behavior using the tests.
The main purpose of the tests is to experimentally investigate the pure seismic torsional behavior of reinforced concrete walls which are under axial load. Thus, ten seismic torsion tests have been carried out by using these specimens. It has been tried to determine optimum load increase by changing load increments in the reference specimen test. The reference specimen test has been used for determining the loading protocol. In addition to these specimens, a reference specimen having a 6 aspect ratio has been produced. Three specimens have been produced from each aspect ratio. Reinforced concrete walls having 7, 6, and 5 aspect ratios have been produced on a 1/2 scale. In this paper, the seismic torsional behavior of reinforced concrete walls has been studied experimentally.
#CRITICAL COMBINED LOADING FOR FLEXTURE COLUMN CRACK#
Torsional strength and stiffness, twist angle, crack pattern, torsional behavior of structural system elements have been investigated by these experimental studies. 2010 Li and Belarbi 2011 Peng and Wong 2011 Okay and Engin 2012 Peng 2012 Chalioris and Karayannis 2013 Defialla et al. 2007 Tirasit and Kawashima 2007 Prakash 2009 Prakash et al. Torsional effects that may occur in reinforced concrete structural system elements have been investigated by many experimental studies in recent years (Wafa et al. 1974 Onsongo 1978 Narayanan and Kareem-Palanjian 1986). When these comprehensive studies are examined, it is seen that although there are studies related to columns and slabs, the studies are generally carried out on beams (Ersoy and Ferguson 19a Hsu 1968b Doudak and Ersoy 1969 Hsu and Kemp 1969 Onsongo and Collins 1972 Ersoy 1973 Karlson et al.
