Acceleration Response-Based Adaptive Strategy for Vibration Control and Location Optimization of Magnetorheological Dampers in Multistoried Structures
Publisher: ASCE
Abstract: Optimization and deployment of control systems with multiple control devices incorporated into a structure is a daunting task. The optimum location of the control device is intrinsically connected to the design parameters ...
Influence of Pulse-Like Near-Fault Ground Motions on the Base-Isolated Buildings with LRB Devices
Publisher: ASCE
Abstract: Seismic base isolation is a passive structural control system that has been effectively utilized as an innovative seismic-resistant design method in the past decades. The properties of earthquake ground motions have ...
Risk-Based Evaluation of Economic Feasibility for Strengthening of Low-Code RC Structures
Publisher: ASCE
Abstract: In this study, the economic feasibility of strengthening several types of low-code RC structures in Bucharest is analyzed. Using recently compiled information regarding the characteristics of the residential building stock ...
Adequacy of Equivalent Static Analysis Method Employing Caltrans, AASHTO, and ATC-32 Provisions in Response Estimation of Vibration-Controlled Bridges
Publisher: ASCE
Abstract: Bridges are among the key elements of the transportation network. Many bridges are severely damaged or destroyed when subjected to earthquakes. One of the effective methods to reduction of a bridge’s seismic damage is to ...
Seismic Loss Estimation Using Experimental Fragility and Vulnerability Functions: Case Study of Buzau County, Romania
Publisher: ASCE
Abstract: This paper is focused on the seismic risk assessment of Buzau County in Romania. This county overlays the most active seismic source in the region, namely, the Vrancea intermediate-depth seismic source which has produced ...
Effect of Flexibly Attached Secondary Systems on Dynamic Behavior of Light Structures
Publisher: ASCE
Abstract: This paper investigates the effect of flexibly attached secondary systems (FSS) on the dynamic behavior of primary structures (PS) under harmonic and seismic ground excitations. An FSS affects the main structure during ...
Enhancing the Structural Performance of RC Beam-Column Joints Using a Novel Optimized Stochastic Lattice Structure
Publisher: ASCE
Abstract: Beam-column (BC) joints play an important role in the seismic performance of moment-resisting RC frame structures. Several techniques have been suggested to improve the seismic efficiency of BC joints, but these techniques ...
Seismic Performance Upgrade of Elevated Water Tanks Utilizing Friction Dampers
Publisher: ASCE
Abstract: Water storage tanks are essential structures in water distribution supply systems. During an earthquake, the damages incurred to water tanks may lead to disastrous loss of life and property. This is due to the low ductility, ...
Nonlinear Seismic Performance Evaluation of Hybrid Base Isolation Systems
Publisher: American Society of Civil Engineers
Abstract: A variety of base isolation systems and their combinations with dampers are applicable in practice. However, most previous studies focused on few numbers of the isolation systems. Therefore, a more comprehensive investigation ...
Wind-Induced Structural Response of Skylights: A Eurocode-Based Assessment
Publisher: ASCE
Abstract: The installation of structural glass systems, such as skylights and curtain walls, may improve the aesthetic and functional value of a building. These attractive systems have practical benefits like increased efficiency ...
