Evaluate the seismic performance of a masonry bearing wall structure in IRAQ

The masonry wall is more types of building systems sensitivity against earthquakes and the fact that this system of construction is widespread in Iraq, especially condominiums. And the fact that Iraq subjected to many earthquakes in recent years and is expected to be subjected to more intensities of earthquakes in the future, engendered an urgent need to investigate the behaviour of this type of construction under the influence of earthquakes. The finite element method used to represent the three-dimensional model using ABAQUS (6-13) program. Model is built with dimensions (5 × 20 m) from the common house models in Iraq. compressive strength of bricks (17MPa) type A and compressive strength of mortar(15MPa) with mixing ratio 1:3 was used to represented of the properties of construction materials in Iraq. The nonlinearity behavior of the materials is considered in this paper. The model is subjected to PGA (0.5g) from EL-Centro Earthquake (1940 N-S) as input ground motion to determine its seismic performance.
