Semiactive Control Algorithms for Structures with Variable Dampers
Publisher: American Society of Civil Engineers
Abstract: Semiactive control systems combine the features of active and passive control to reduce the response of structures to various dynamic loadings. They include: (1) Active variable stiffness, where the stiffness of the structure ...
Discussion: Vibration Control of Tall Buildings Using Mega Subconfiguration
Publisher: American Society of Civil Engineers
Peak Non-Gaussian Wind Effects for Database-Assisted Low-Rise Building Design
Publisher: American Society of Civil Engineers
Abstract: Current procedures for estimating the peaks of the stochastic response of tall buildings to wind are based on the assumption that the response is Gaussian. Those procedures are therefore inapplicable to low-rise buildings, ...
Modeling and Analysis of Single-Plate Shear Connections under Column Loss
Publisher: American Society of Civil Engineers
Abstract: This paper presents a computational assessment of the behavior of single-plate shear (shear tab) connections in gravity frames under column-loss scenarios. Two-span beam assemblies without floor slabs are considered under ...
Linear Procedures for Structures with Velocity-Dependent Dampers
Publisher: American Society of Civil Engineers
Abstract: Passive energy dissipation devices are used to reduce the damage from earthquakes by absorbing a portion of the earthquake-induced energy in structures. Wide acceptance of these devices in structures will depend on the ...
Discussion of “Definition of Wind Profiles in ASCE 7” by Yin Zhou and Ahsan Kareem
Publisher: American Society of Civil Engineers
Progressive Collapse Resistance of Steel-Concrete Composite Floors
Publisher: American Society of Civil Engineers
Abstract: This paper discusses the progressive collapse resistance of steel-concrete composite floors in which steel beams are attached to columns through shear tabs. This is a common type of system used for the gravity bay portions ...
Closure to “Progressive Collapse Resistance of Steel-Concrete Composite Floors” by Yasser Alashker, Sherif El-Tawil, and Fahim Sadek
Publisher: American Society of Civil Engineers
Database-Assisted Wind Load Capacity Estimates for Low-Rise Steel Frames
Publisher: American Society of Civil Engineers
Abstract: A comparative study is presented of the estimated wind load capacities of low-rise steel building frames based on loading patterns (magnitude and distribution) established from aerodynamic databases on the one hand, and ...
Robustness of Composite Floor Systems with Shear Connections: Modeling, Simulation, and Evaluation
Publisher: American Society of Civil Engineers
Abstract: This paper presents a computational investigation of the robustness of a typical concrete deck–steel beam composite floor system with simple shear connections in the event that a center column has been removed. The study ...
