concrete shear walls are the most prevalent structural systems resisting lateral loads due to earthquakes in high-rise buildings. very large in-plane stiffness of shear walls provides an excellent drift control in the structure. however, structural damages and early code shortcomings threaten the efficiency of existing structural walls against earthquake. recently, fiber reinforced polymer (frp...

the steel shear wall and composite steel plate shear wall is introduced in recent three decade and is considered and is spread rapidly. composite steel plate shear wall which is made of a layer of thin steel sheet with coating of reinforced concrete in one or both sides of steel palate is considered a third generation of resistance shear walls against lateral loads that in addition to increasin...

verifying the behavior of shear walls in a tall building requires reliable response results. this paper examined nonlinear fiber element modeling of a slender reinforced concrete shear wall during large-scale shaking table testing. the goal was to understand and validate the inelastic responses given by fiber models using time history analysis. reasonable agreement was found between the numeric...

The addition of steel fibers into concrete improves the postcracking tensile strength of hardened concrete and hence significantly enhances the shear strength of reinforced concrete reinforced concrete beams. However, developing an accurate model for predicting the shear strength of steel fiber reinforced concrete (SFRC) beams is a challenging task as there are several parameters such as the co...

the combination of flexural frame and shear wall is one of the suitable systems to apply in reinforced concrete buildings. the deflections of flexural frame become limited due to the high stiffness of wall and the interaction of these systems. tall buildings even higher than fifty stories can be designed by using frame- wall systems. with respect to special behavior of flexural frame or shear w...

Masonry infill has been widely used as building material due to its cost effectiveness and availability.  The failure of these masonry infill walls during the past earthquakes have underscored the importance of ensuring the safety of the infill walls when it is subjected to lateral loads. In-plane and out of plane failures have been observed in many reinforced concrete framed building with maso...

The main objective of this study was to numerically assess the effect of boundary elements with different types of steel and concrete materials on nonlinear behavior of composite steel–reinforced concrete wall (CSRCW) by employing ABAQUS software. Two types of common steel profiles including box and I-shaped sections, located at the middle and extremities of the wall, were employed to assess th...

Strengthening of the existing seismically deficient reinforced concrete (RC) buildings is an important issue in earthquake prone regions. Addition of RC shear wall as infill or external walls into the structural system has been a commonly preferred strengthening technique since the Big Erzincan Earthquake occurred in Turkey, 1992. The newly added rigid infill walls act primarily as shear walls ...
