RISModeling of Coupled Shear Walls and Its Experimental Verification
Publisher: American Society of Civil Engineers
Abstract: Coupled shear wall is one of the main structural elements in high-rise buildings. In this paper, a nonlinear macromodel is proposed to simulate the behavior of coupled shear walls. This model is composed of a multivertical-element ...
Experimental Hysteretic Behavior and Application of an Assembled Self-Centering Buckling-Restrained Brace
Publisher: ASCE
Abstract: In this paper, we propose an assembled self-centering buckling-restrained brace (ASCBRB), which eliminates the residual drift of structures after a major horizontal displacement. The ASCBRB also represents an advanced ...
Tendon Model for Nonlinear Analysis of Externally Prestressed Concrete Structures
Publisher: American Society of Civil Engineers
Abstract: The present study describes a nonlinear analysis model developed for externally prestressed structures. This model is capable of simulating the slip of the tendon on the deviator and the friction at the interface of the ...
Shaking Table Test and Numerical Analysis of RC Frames with Viscous Wall Dampers
Publisher: American Society of Civil Engineers
Abstract: This paper presents a comprehensive investigation on viscous wall dampers (VWD) used for seismic response mitigation of reinforced concrete (RC) frames. First, a shaking table test on a large-scaled three-story RC frame ...
Local Buckling Restraining Behavior of Thin-Walled Circular CFT Columns under Seismic Loads
Publisher: American Society of Civil Engineers
Abstract: The local buckling restraining behavior of thin-walled circular concrete-filled tubular (CFT) columns is examined under seismic loads by conducting a bidirectional cyclic loading and a bidirectional shaking table test. ...
Length Scales Interaction in Nonlocal Plastic Strain Localization of Bars of Varying Section
Publisher: American Society of Civil Engineers
Abstract: In computational mechanics, strain softening generates ill-posed boundary value problems, which cannot be solved without being regularized, e.g., through the introduction of an internal length scale. This paper investigates ...
Experimental Study of Self-Centering Shear Walls with Horizontal Bottom Slits
Publisher: American Society of Civil Engineers
Abstract: This paper introduces a new design form for prestressed shear walls with horizontal bottom slits utilizing cast-in-place technology. Horizontal slits are placed symmetrically at the wall-foundation interface of prestressed ...
Ultimate State of Thin-Walled Circular Steel Columns Subjected to Biaxial Horizontal Forces and Biaxial Bending Moments Caused by Bidirectional Seismic Accelerations
Publisher: American Society of Civil Engineers
Abstract: To check the safety of thin-walled circular steel columns used for bridge piers of elevated-girder bridges, a versatile interaction equation is derived to specify the ultimate state of the columns under the coupling of ...
Influence of Axial Load Ratio on the Seismic Behavior of Steel Fiber–Reinforced Concrete Composite Shear Walls
Publisher: ASCE
Abstract: The seismic behavior of shear walls is significantly influenced by the axial load ratio (ALR), and a maximum ALR limit is generally specified by current seismic design code. To achieve improved performance under a high ...
