In Situ Lateral Load Testing of a Two-Story Solid Clay Brick Masonry Building

The seismic behavior of unreinforced masonry (URM) structures has usually been investigated by conducting laboratory tests. Such efforts, although useful in order to understand the response of single walls or subassemblages, cannot fully mimic the in situ seismic response of masonry buildings. In this study, in situ lateral load testing of a two-story full-scale URM building was conducted. First, forced vibration tests were performed to determine the vibration frequencies of the building. Afterwards, the building was tested by reacting against a braced steel frame built behind the test building and imposing one-way cyclic displacements. The building was pushed until 20% loss of lateral load capacity, which corresponds to a drift ratio of approximately 0.8%. The diagonal tension cracking of the walls was followed by sliding of the second-story concrete slab over the walls. A three-dimensional nonlinear finite-element analysis of the test building was conducted to simulate the behavior of the test building. The results showed that upon careful selection of the contact cohesion at the slab-wall interfaces, the numerical model provided reasonable estimations of the global structural behavior in terms of load-deformation response.


Analytical Investigation of Lateral Strength of Masonry Infilled RC Frames Retrofitted with CFRP
Erdem, Ibrahim; Akyüz, Uğurhan (American Society of Civil Engineers (ASCE), 2010-07-01)
In this study, two reinforced concrete frames with hollow clay tile masonry infill walls, retrofitted with diagonally applied carbon fiber-reinforced polymer (CFRP), which were tested previously, were analytically investigated. A simple material model for the masonry infill wall strengthened with CFRP is suggested. The lateral strength of each rehabilitated frame was obtained by pushover analysis of four different models using a commercially available finite-element program, and the results were compared wi...
Seismic Performance Assessment of Masonry Buildings Using In Situ Material Properties
Cobanoglu, Baran; ALDEMİR, ALPER; Demirel, Ismail Ozan; Binici, Barış; Canbay, Erdem; Yakut, Ahmet (American Society of Civil Engineers (ASCE), 2017-08-01)
Seismic performance assessment of existing buildings requires the existing material's properties to be determined as this has a significant influence on the seismic risk. As one of the most common construction type in Turkey, masonry buildings are assessed generally based on the recommended material properties specified in relevant codes as opposed to testing of samples taken from the existing buildings. However, due to different material types and workmanship quality, the specified properties might be quit...
Seismic behaviour of roller compacted concrete dams under different base treatments
Gharibdoust, Ali; ALDEMİR, ALPER; Binici, Barış (Informa UK Limited, 2019-09-09)
The effect of base roughness on the seismic behaviour of roller compacted concrete gravity dams were investigated by pseudo-dynamically testing two 1/75 scaled specimens with smooth and rough base treatments. Both specimens were tested under the effect of three different hazard level earthquakes and also a pushover experiment was conducted to obtain the capacity curve of each specimen. The smooth base specimen exhibited significant sliding under the effect of the maximum credible earthquake motion. In contr...
Probabilistic assessment of earthquake insurance rates for important structures: Application to Gumusova-Gerede motorway
Yücemen, Mehmet Semih; ERDİK, MUSTAFA ÖZDER (Elsevier BV, 2008-01-01)
A probabilistic model is presented for the assessment of the earthquake insurance rates for important engineering structures, for which the seismic losses could be quite significant. The proposed model is used to estimate the earthquake insurance premiums for the structures taking place in the Bolu Mountain Crossing in the Gumusova-Gerede motorway Section, Turkey. The model requires two types of studies, namely: seismic hazard analysis and estimation of potential damage to structures based on damage probabi...

A stochastic framework is developed, in terms of the theory of homogeneous random functions, to estimate the seismic hazard associated with linearly extending seismic sources. The formulation is carried out in the space-time domain. An earthquake having at least a magnitude of m is assumed to occur whenever the total strain energy accumulated over the potential rupture plane exceeds the energy level corresponding to this magnitude, m. An alternative formulation, in which an earthquake is generated when the ...
