- Effects of Infilled Masonry Walls on Nonliner Structural Behavior of Precast Concrete Structures in Turkey

- Description
- Turkey is one of earthquake prone country. 90% of its buildings is under earthquake risk. 1998 Adana and 1999 Marmara earthquakes caused high damages not only in high rise buildings but also in important industrial buildings too. In the recent earthquakes, large numbers of people have died or heavily injured in the complete collapse of buildings constructed with reinforced and precast concrete structures. In Turkey, most of the industrial buildings are prefabricated structures. In industial zones precast concrete structures are prefered
because of their economic and rapid production. It is a fact that a large part of the industrial regions are located on high risk earthquake zones. In the design of precast concrete structures, frames are generally analyzed in two dimensions. The infill masonry walls increase the stiffness and lateral capacity of the frame structures. Although, infill masonry walls increase these parameters, infill walls are generally not taken into consideration in the lateral load capacity of precast concrete structures. In the present study, in order to determine the effects of infill walls in earthquake behavior of single story hinged prefabricated industrial buildings in Turkey, the capacities of these buildings which were related with different parameters as concrete strength, column dimension, reinforcement ratio, soil class, story height and truss span, were determined. In the analyses, diagonal strut model is adopted for modeling masonry infill walls. Structural behaviors and load deformation relationship of precast concrete structures both with and without infilled walls are evaluated and compared.

- A Rational Approach to Analytical Modeling of Masonry Infills in Reinforced Concrete Frame Buildings

- Description
- Masonry infills, which generally have high stiffness and strength, play a crucial role in lateral load response of reinforced concrete (RC) frame buildings. Geographically, there is a large variation in material properties of masonry. Moreover, masonry behaves in a highly nonlinear manner. Therefore, a generalized yet rational model is required for masonry infills that can efficiently incorporate its linear and nonlinear material properties and common failure modes in RC members and masonry infills under the action of lateral forces. Interestingly,
national codes of most of the countries do not specify modeling procedures for such structural systems. On the other hand, several analytical models for masonry infills are available in literature, for example, equivalent diagonal strut models, finite element models, etc. Therefore, a comparative study was carried out considering different analytical models for masonry infills using experimental results for nonlinear material properties of masonry infills. Analytical models considered in the present study include single-strut model, 3-strut model, and finite element models. By linear and non-linear analyses, it was observed that the 3-strut model can estimate force resultants in RC members with sufficient accuracy, in addition to modeling the local failures in infills and in beams and columns due to interaction between masonry infills and RC frame. It was also observed that the single-strut model can be effectively used in cases where masonry infill walls are discontinued in the first-storey to generate parking space (for example, soft or open storey buildings).

- Keywords: unreinforced masonry ; hysteresis model
- Description
- Unreinforced masonry (URM) walls have been traditionally perceived to possess very little displacement capacity with respect to out-of-plane loading. This view, which has arisen due to low tensile strength of URM and therefore small displacements at which such walls begin to crack, has led to the widespread misconception among engineers that such walls possess no ductility and perform poorly under earthquake loading. However,
both theoretical and experimental research have in fact shown that URM walls have the capacity to undergo significant deformations before collapse occurs, due to the rigid block action and frictional resistance mechanisms present in such walls. In addition, walls supported at their vertical edges have been shown to possess good energy dissipation characteristics which is further beneficial to seismic resistance. This paper presents a time history analysis model developed for simulating the dynamic response of URM walls subjected to out-of-plane loading. The hysteresis model incorporated into the analysis is capable of representing the nonlinear load versus displacement behaviour of walls with a range of boundary conditions that include one-way and two-way walls. The various parameters in the model can be calculated as a function of the properties of the URM wall, including the dimensions, material properties, axial loading and boundary support conditions. Comparisons of the analytical model with experimental shaketable tests show promising results.
