Mechanical Responses of Steel Fiber–Reinforced Concrete after Exposure to High Temperature: Experiments and Mesoscale Discrete Modeling
(ASCE, 11/1/2021)The mechanical responses of steel fiber–reinforced concrete (SFRC) thermally damaged at high temperature needs a deeper evaluation via a mesoscopic model that explicitly treats the fibers. For this demand, the lattice ... -
Time-Domain Method for Correction of Aerodynamic Loads in High-Frequency Force Balance Tests
(ASCE, 10/1/2021)The high-frequency force balance (HFFB) technique is commonly used in wind tunnels to investigate the wind loads and wind-induced responses of high-rise buildings. This paper presents a time-domain correction method for ... -
Two Different Approaches for Collapse of Nonsymmetric Masonry Arches: Monasterio’s Treatment versus Limit Equilibrium Analysis
(ASCE, 10/1/2021)This research can be viewed as a development of the critical review of the Monasterio’s manuscript Nueva teórica sobre el empuje de bóvedas, proposed by the authors in previous studies; this unpublished manuscript is devoted ... -
Modeling of Disc Spring Self-Centering Energy Dissipation Braces from Inactive State to Design Limit State
(ASCE, 10/1/2021)This paper focuses on modeling the hysteretic behavior of disc spring self-centering energy dissipation braces (DS-SCEDBs) from the inactive state to the design limit state, and proposes two restoring force models for ... -
Advanced Modeling of a Historical Masonry Umbrella Vault: Settlement Analysis and Crack Tracking via Adaptive NURBS Kinematic Analysis
(ASCE, 11/1/2021)In this work, the study of a complex masonry umbrella vault located within Masegra Castle (Museum of Sondrio territory, Northern Italy) is presented. Built during the renewal of the castle in the 16th century, the umbrella ... -
Scaling Laws for Rigid-Body Response of Masonry Structures under Blast Loads
(ASCE, 10/1/2021)The response of masonry structures to explosions cannot be exclusively investigated relying only on numerical and analytical tools. Experimental tests are of paramount importance for improving current understanding and ... -
Numerical Block-Based Simulation of Rocking Structures Using a Novel Universal Viscous Damping Model
(ASCE, 11/1/2021)Unreinforced masonry structures, particularly façade walls, are seismically vulnerable due to their weak connections with adjacent walls, floors, and/or roofs. During an earthquake, such walls formulate local mechanisms ... -
Spatial Variation in Sensitivity of Hurricane Surge Characteristics to Hurricane Parameters
(ASCE, 10/1/2021)Mitigating losses from a storm surge requires an accurate prediction of its peak, duration, and current speed along the coastline. Because this prediction depends on varying atmospheric and oceanic conditions, the uncertainty ... -
Inelastic Response of Base-Isolated Tall Buildings under Nonstationary Winds: Response History Analysis and Statistical Linearization Approach
(ASCE, 10/1/2021)This study investigated uncoupled crosswind and alongwind responses of base-isolated tall buildings under nonstationary wind excitations. The base isolation system has hysteretic restoring force characteristics represented ... -
Interpretation of Real-Time Hybrid Simulation as Neutral and Retarded Delay Systems for Its Stability Analysis
(ASCE, 10/1/2021)As an economical and effective testing method, real-time hybrid simulation (RTHS) can be understood as a dynamic system with substructure feedback, where the time delay in feedback caused by servo-hydraulics may destabilize ... -
Simultaneous Assessment of Damage and Unknown Input for Large Structural Systems by UKF-UI
