RISProgressive Collapse of Steel Moment Frames Subjected to Vehicle Impact
Publisher: American Society of Civil Engineers
Abstract: Structures are often subjected to vehicle collision, which can be accidental or intentional as in the case of a terrorist attack. This study investigated the performance of three-story steel moment frames with span length ...
Seismic Performance Evaluation of Nonseismic Designed Flat-Plate Structures
Publisher: American Society of Civil Engineers
Abstract: In this study the seismic performance of flat plate system structures designed without considering seismic load was investigated. Both the capacity spectrum method provided in ATC-40 in 1996 and nonlinear dynamic analyses ...
Displacement-Based Design of Supplemental Dampers for Seismic Retrofit of a Framed Structure
Publisher: American Society of Civil Engineers
Abstract: The procedure of direct displacement-based design (DBD), presented in the SEOAC
Damage Mitigation of a Steel Column Subjected to Automobile Collision Using a Honeycomb Panel
Publisher: ASCE
Abstract: This study investigates the performance and design of an aluminum honeycomb panel attached to the face of a steel column for reducing local damage caused by vehicle collision. The dynamic plateau stress of the honeycomb ...
Seismic Retrofit of Framed Buildings Using Self-Centering PC Frames
Publisher: ASCE
Abstract: In this study, self-centering post-tensioned precast concrete (PC) frames are developed for seismic retrofit of reinforced concrete (RC) framed structures. The cyclic loading test of a RC frame retrofitted with a SC-PC ...
Seismic Retrofit of Structures Using Hybrid Steel Slit–Viscoelastic Dampers
Publisher: ASCE
Abstract: A hybrid steel slit–viscoelastic damper (HSVD) has been developed to enhance seismic performance of a structure. To model viscoelastic behavior, an analytical model is developed based on the Kelvin–Voigt and Bouc–Wen–Baber–Noori ...
Seismic Performance Evaluation and Retrofit of Fixed Jacket Offshore Platform Structures
Publisher: American Society of Civil Engineers
Abstract: In this study the seismic performances of the fixed-base jacket structures with various bracing configurations were evaluated by nonlinear static and dynamic methods, and the effects of various retrofit schemes were compared. ...
Investigation of Progressive Collapse-Resisting Capability of Steel Moment Frames Using Push-Down Analysis
Publisher: American Society of Civil Engineers
Abstract: In this study the vertical push-down analysis was conducted to investigate the resistance of steel moment frames for progressive collapse. The analysis was carried out by gradually increasing the vertical displacement in ...
Thermodynamic Behaviors of a Viscoelastic Plate for Vibration Control with Nonlocal Effect and Temperature-Dependent Properties when Subjected to a Moving Heat Source
Publisher: ASCE
Abstract: Viscoelastic materials are used widely for seismic mitigation and vibration suppression in civil engineering, and have obvious advantages in energy dissipation. Viscoelastic materials and devices are often used in a ...
Experimental and Theoretical Study on Nonlinear Behavior of Compression-Mode Viscoelastic Dampers under Different Excitations and Temperatures
Publisher: ASCE
Abstract: This work designs a new compression-mode viscoelastic (VE) damper to avoid bonding interface failure in classical shear-mode VE dampers. However, most existing mathematical models based on the shear deformation at the ...
