چکیده
The beam-only connected reinforced concrete shear wall (BRW) is used as a reinforcing component to enhance the seismic performance of concrete-filled, double-skin steel tube (CFDST) frames. effects BRW on risks CFDST frames are investigated. Three levels limit states defined and described according typical failure test specimens existing definition current guidance. A simplified numerical model calibrated for frame-BRW structures, results validate it. Nonlinear dynamic analyses nine-story CFDST-BRW building performed investigate reducing risk buildings. show that reduces probability collapse frame 2.76% in 50 years, which can effectively reduce different degrees damage service cycle structure. provide information risk-informed decision-making design structures.

Seismic Behavior of Steel Reinforced Concrete Beam-Columns and Frames
The ability to perform accurate nonlinear simulations is a key component in the assessment of the behavior of seismic force resisting systems. A three-dimensional distributed plasticity formulation for composite beam-columns suitable for nonlinear static and dynamic analyses of composite seismic force resisting systems has been developed. New uniaxial constitutive relations are developed for th...
متن کاملSeismic Performance of Steel Plate-Reinforced Concrete Composite Shear Wall
In tall buildings the reinforced concrete (RC) shear wall is one of the predominant structural components used to resist lateral loads induced by earthquakes around the world. Previous research demonstrated that shear walls displayed a sudden loss in lateral capacity due to the wall corner and web crushing in the plastic zone. In addition, it was found that large shear distortions in shear wall...

متن کاملA Macro-model for Nonlinear Analysis of 3D Reinforced Concrete Shear Walls
Architectural limitations in many situations make it necessary for the RC shear walls to be extended in plan in different directions at a single location that makes them a 3D configuration. Analysis of such walls is very challenging. In this research about 450 cases of 3D shear walls are considered with different shapes and heights. L, T and H-shape walls are studied. They are nonlinearly analy...
