Comparative Study of Frames Using Viscoelastic and Viscous Dampers
Publisher: American Society of Civil Engineers
Abstract: Identical mathematical expressions for viscoelastic and viscous damper-brace components are derived as the function of two fundamental nondimensional parameters. These two parameters are used to investigate the properties ...
Spectral Relative Motion of Two Structures due to Seismic Travel Waves
Publisher: American Society of Civil Engineers
Abstract: This paper proposes a spectral difference method to estimate the maximum relative displacement between adjacent elastic structures subjected to seismic traveling waves. The method, based on random vibration theory, seeks ...
General Behavior of WF Steel Shear Link Beams
Publisher: American Society of Civil Engineers
Abstract: The behavior of different length wide flange (WF) links in eccentrically braced steel frames with or without axial force application, were experimentally investigated using a subassemblage system simulating the frame action. ...
Cyclic Web Buckling Control for Shear Link Beams
Publisher: American Society of Civil Engineers
Abstract: Shear links employed in Eccentrically Braced Frames (EBFs) must be appropriately stiffened in order to prevent premature web buckling and retain energy dissipation capability for subsequent cyclic loading. Criteria for web ...
Analysis for a Type of Structural Pounding
Publisher: American Society of Civil Engineers
Abstract: The formulation and solution of the multiple degree of freedom equations of motion for a type of structural pounding are presented. The subject building undergoes pounding at a single floor level with a rigid adjacent ...
Discussion of “<i>Applications of Viscoelastic Dampers to High‐Rise Buildings</i>” by C. S. Tsai and H. H. Lee (April, 1993, Vol. 119, No. 4)
Publisher: American Society of Civil Engineers
Passive Control Systems for Seismic Damage Mitigation
Publisher: American Society of Civil Engineers
Abstract: This paper proposes a simplified theory to predict and compare the seismic performance of viscoelastical (VE)- and elastoplastical (EP)-damped passive control systems, and to demonstrate their ability to protect structures ...
Inelastic Vibration Phase Theory for Seismic Pounding Mitigation
Publisher: American Society of Civil Engineers
Abstract: Pounding between closely spaced structures can be a serious hazard in seismically active metropolitan areas. One of the key issues is estimating the required separation distance to avoid or reduce pounding of adjacent ...
Rotation Capacity of I-Shaped Beams with Concrete Slab in Buckling-Restrained Braced Frames
Publisher: ASCE
Abstract: Buckling-restrained braced frames (BRBFs) are attracting interest worldwide by virtue of their extraordinary response reduction performance. The system relies strongly on the energy dissipation of buckling-restrained braces ...
Rotation Capacity of I-Shaped Beams under Alternating Axial Forces Based on Buckling-Mode Transitions
Publisher: ASCE
Abstract: During earthquakes, I-shaped beams (I-beams) in a braced structure are subjected to the flexural moment synchronized with reversed axial forces transmitted from buckling restrained braces. A prior study used the modified ...
