Predefined damage patterns for limit analysis on non-engineered masonry buildings

2018-06-18
Non-engineered masonry construction still constitutes a significant percentage of building stocks, especially in earthquake-prone Mediterranean, Asian and South American countries. It is not easy to quantify the seismic performance of this building type, because the analytical and numerical methods, which have been developed so far, generally work for engineered masonry buildings with specific design and construction practices. For such buildings, it is easy to define the load transfer paths through well-defined structural members. However, nonengineered masonry buildings generally do not have well-quantified material properties, rigid floor diaphragms and adequate floor-to-wall or wall-to-wall connections in order to ensure such a load path. Hence the use of conventional analysis tools become meaningless or even misleading since the seismic behavior of nonengineered buildings contradicts with the fundamentals of structural analysis and modeling, on which these analysis tools are based on. In such cases, the use of kinematical approach, which is mostly based on observed performance and damage on the considered building type, may provide a practical solution. This study aims to propose prescribed in-plane damage mechanisms and crack patterns for solid and perforated masonry walls by using the available post-earthquake field data obtained from damaged masonry buildings and experimental data obtained from masonry specimens. These predefined damage and crack patterns can be used as an input for limit analysis theorems in order to estimate the lateral load capacity of non-engineered masonry buildings.

Testing of an existing two story masonry building under lateral loads
Aldemir, Alper; Binici, Barış; Canbay, Erdem; Yakut, Ahmet (null; 2017-01-13)
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 progr...
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...
Integrated Management of Archaeological Heritage: Mediterranean Coasts of Turkey
Nayci, Nida; Şahin Güçhan, Neriman (2007-11-17)
Mediterranean coastal areas possess great amount of historic and archaeological assets joined up with ecological and natural values. Many of these fragile environments were originally constructed on the dry-lands, which have been transformed into different environmental context with the evolution of coastal areas Over centuries and millennia. Today, increased population and poorly planned coastal activities are conflicting with the conservation principles of these fragile environments.
Modeling of lithology induced chemical anomalies in the aquifer systems of the Kazan Trona deposit area, Ankara, Turkey
Çamur, Mehmet Zeki; Yazıcıgil, Hasan (2008-04-01)
The study was carried out in order to investigate existing hydrogeochemical relationships between groundwater environment and geological units in the Kazan trona deposit area, Ankara, Turkey. Evaluations indicate that concentrations of alkalinity, boron, chloride and sodium in the upgradient groundwater of the Eocene sedimentary units gradually increase toward downgradient by the interactions of saline minerals (searlesite, shortite, northupite and pyrite) present in the secondary structures (microfractures...
