Although performance based assessment procedures are mainly developed for reinforced concrete and steel buildings, URM buildings occupy significant portion of building stock in earthquake prone areas of the world as well as in Turkey. Variability of material properties, non-engineered nature of the construction and difficulties in structural analysis of perforated walls make analysis of URM buildings challenging. Despite sophisticated finite element models satisfy the modeling requirements, extensive experimental data for definition of material behavior and high computational resources are needed. Recently, nonlinear equivalent frame models which are developed assigning lumped plastic hinges to isotropic and homogenous equivalent frame elements are used for nonlinear modeling of URM buildings. The work presented in this thesis is about performance assessment of unreinforced brick masonry buildings in Turkey through nonlinear equivalent frame modeling technique. Reliability of the proposed model is tested with a reversed cyclic experiment conducted on a full scale, two-story URM building at the University of Pavia and a dynamic shake table test on a half scale, two story URM building at the Ismes Laboratory at Bergamo. Good agreement between numerical and experimental results is found. Finally, pushover and nonlinear time history analyses of three unreinforced brick masonry buildings which are damaged in 1995 earthquake of Dinar is conducted using the proposed three dimensional nonlinear equivalent model. After displacement demands of the buildings are determined utilizing Turkish Earthquake Code 2007, performance based assessment of the buildings are done.

A simplified method for determining sway in reinforced concrete dual buildings and design applications TEKELİ, Hamide; Atimtay, Ergin; TÜRKMEN, Mustafa (2013-10-25) Sway analyses of reinforced concrete buildings generally are carried out with computer programs. However, as the number of iterative solutions increase, the process may become tedious. This paper proposes a simple analytical method to evaluate sway of dual buildings subject to various types of lateral loads. The proposed method is based on the continuum model. Story drift limited by building codes can be controlled by the proposed method. Likewise, design engineers can use the simple analytical expressions ...
A comparative study on different analysis approaches for estimating the axial loads on columns and structural walls at tall buildings Kurç, Özgür (Wiley, 2013-04-01) Estimating axial loads on columns and structural walls at tall buildings is a complicated task because time-dependent deformations of concrete and the way the building is constructed affect the way the gravity loads are carried by them. The accurate computation of axial loads is crucial for determining the size and strengths of columns and structural walls. This study investigates several analysis approaches commonly used during the design of such buildings. Construction sequences, time-dependent deformatio...
The Impact of surface texture and wind on convective heat transfer from building façades Öztürel, Necil; Elias Özkan, Soofia Tahira; Department of Building Science in Architecture (2013) In this study, the impact of the surface texture of finishing materials and wind conditions on heat loss from the building’s facade are investigated. Three sets of samples (Set A, B and C) are tested and observed under varying wind speeds and varying wind angles in a wind tunnel. Both Sets A and B are composed of seven samples each, all having different surface textures. Set A samples were prepared from gypsum plaster and Set B samples from cement plaster mix. Set C consists of five different samples of con...
Evaluating the impact of different atria configurations on the energy performance of buildings in different climates Farhoudi, Meysam; Elias Özkan, Soofia Tahira; Department of Building Science in Architecture (2016) Generally, the impact of the building sector on the world energy consumption and environmental protection is considerable; in fact, the building sector holds the half of the world total energy consumption share. Nowadays, energy efficiency phenomena as the result of several challenges that the world is encountering has become an important issue. Meanwhile, the atrium as a tool to improve the energy performance of a building can be utilized to address the high energy consumption of the conventional buildings...
Modelling of strengthened hollow brick infills BARAN, MEHMET; Ozcelik, Ramazan; Sevil, Tugce; Canbay, Erdem (2013-02-01) Strengthening the existing hollow brick infill walls by bonding high-strength precast concrete panels or applying steel fibre reinforced mortar was found to be an occupant-friendly seismic retrofitting technique for the buildings in use with deficient reinforced concrete structural systems. Both techniques convert the existing non-structural hollow brick infill walls into load-carrying structural members. To verify the effectiveness of the techniques, 20 reinforced concrete frames with hollow brick infill w...
