Testing of an existing two story masonry building under lateral loads

Masonry structures constitute a significant portion of the building stock in many countries with high seismic regions. Understanding the load carrying mechanisms of such buildings and estimating the deformation capacities is important for seismic risk mitigation. In the process of developing new assessment guidelines for Turkey, a comprehensive research project was conducted in order to estimate the expected seismic performance of existing masonry buildings. Within the scope of this extensive research program, an existing two-story masonry building was tested under lateral cyclic loads on site. A seven meter high steel reaction frame capable of resisting 3000kN base shear force was constructed next to the test building. Afterwards, hydraulic actuators attached to the reaction frame were employed to impose one way cyclic displacement excursions. Flexural and shear deformations on a number of walls were measured and crack prorogations were monitored. The structure was tested up to a lateral strength drop of approximately twenty percent from the ultimate load, which occurred at a drift ratio of about 1.2%. The damage in the walls in the building, which were mostly diagonal tension, concentrated mostly in the second story. In addition, sliding shear failure between the second floor slab and walls are observed.

Lateral Load on Site Testing of a Two Story Masonry Building up to Near Collapse
Binici, Barış; Canbay, Erdem; Yakut, Ahmet (2015-11-06)
Masonry structures constitute a significant portion of the building stock in many countries with high seismic regions. Understanding the load carrying mechanisms of such buildings as a system and estimating the deformation capacities still remains as an important task for seismic assessment and retrofit. In this research, one-way cyclic test of an existing masonry building was performed to determine its lateral load resisting behaviour. The test building was sliced approximately in the middle and one side w...
Analysis on the mechanical properties of historical brick masonry after machinery demolition
Ucer, Deniz; Ulybin, Aleksey; Zubkov, Sergey; Elias Özkan, Soofia Tahira (2018-02-10)
The demolition process of a historical brick masonry building in St. Petersburg, Russia was observed as a case study and research was conducted on the possibility of reusing the resultant debris, which was composed of high quality brick masonry, as new building material. Therefore, samples from the demolition debris, i.e. brick, mortar and wall pieces were collected and tested for their mechanical properties, according to Russian standards, when available, and according to International Standards for the re...
Assessment of seismic behavior of traditional timber frame Ottoman houses: Frame tests
Aktas Erdem, Y. D.; Akyuz, U.; Erdil, B.; Türer, Ahmet; Şahin Güçhan, Neriman (2010-01-01)
There are numerous observations made following a number of historic and contemporary earthquakes, claiming that the Ottoman traditional timber-frame, himis, houses have an inherent seismic resistant property. It is argued that timber frame houses behaved better under earthquake loading, based on the fact that the number of collapsed timber structures is less than the other construction types. In most of the reported cases, however, comparisons made for the seismic performances of himis houses and the others...
A Critique on the Turkish Earthquake Code Regulations Regarding Masonry Construction
Erberik, Murat Altuğ; Ay, Bekir Özer (2008-11-07)
Masonry is still a commonly used type of residential construction in rural and even in urban regions. Unfortunately, the strength and stability of masonry structures are critical in the case of high amplitude cyclic lateral loads such as earthquake ground motion. Hence, the masonry buildings with structural deficiencies belong to the most vulnerable class of structures which have experienced heavy damage or even total collapse in previous earthquakes, especially in developing countries like Turkey. The dama...
Analysis of a multi-story reinforced concrete residential building damaged under its self-weight
Korkmaz, Hasan Husnu; Yakut, Ahmet; Bayraktar, Atilla (Elsevier BV, 2019-04-01)
Reinforced concrete framed residential buildings are remarkably common in Turkey. Observations after recent earthquakes revealed that a great portion of the present building stock has inadequate seismic resistance. Moreover, collapses of several multi-story reinforced concrete buildings under their self-weight have also been observed despite any dynamic activity. The tragic example of the collapse of the "Zumrut" residential building under its self-weight in 2004 and the death of its 93 occupants have highl...
