RISPerformance-Based Wind Engineering of Tall Buildings Examining Life-Cycle Downtime and Multisource Wind Damage
Publisher: ASCE
Abstract: Structural performance against wind hazards is necessary in modern tall building design. In current wind engineering practice, most efforts focus on structural safety, such as the avoidance of large deformations. Besides ...
Physics-Based Method for the Removal of Spurious Resonant Frequencies in High-Frequency Force Balance Tests
Publisher: American Society of Civil Engineers
Abstract: The high-frequency force balance (HFFB) test is a widely used method for estimating lateral turbulent wind loads on tall buildings in a wind tunnel. The method relies on use of a highly accurate force sensor placed at the ...
Poromechanical Microplane Model with Thermodynamics for Deterioration of Concrete Subjected to Freeze–Thaw Cycles
Publisher: ASCE
Abstract: Mechanical deterioration of concrete structures by freeze–thaw cycles has been widely spotted, mainly in temperate zones. In order to incorporate the icing-induced microdefects into global damage, a poromechanical model ...
Data-Based Windstorm Type Identification Algorithm and Extreme Wind Speed Prediction
Publisher: ASCE
Abstract: The extreme wind speed estimation method, which is critical for designing wind load calculation for building structures, should consider windstorm climate types for mixed climates. However, it is very difficult to obtain ...
Non-Gaussian Turbulence Induced Buffeting Responses of Long-Span Bridges
Publisher: ASCE
Abstract: Conventionally, for turbulence-induced buffeting vibrations, the Gaussianity assumption is applied to all three subsequent stages of turbulence, wind loads, and structural vibrations because of its wide applicability and ...
Mesoscopic Analysis of the Compaction Characteristics of Rockfill Materials Considering Gradation and Shape
Publisher: ASCE
Abstract: The development of high rockfill dams has imposed greater demands on the compaction quality of rockfill materials. However, because rockfill particles are subjected to crushing under the compaction of a high-powered roller, ...
Life-Cycle Assessment of Long-Span Bridge’s Wind Resistant Performance Considering Multisource Time-Variant Effects and Uncertainties
Publisher: ASCE
Abstract: This paper examines the life-cycle wind resistant performance of a constructed long-span suspension bridge in the coastal region of China, aiming to quantify the multisource time-variant effects and uncertainties and ...
Wind-Induced Buffeting Vibration of Long-Span Bridge Considering Geometric and Aerodynamic Nonlinearity Based on Reduced-Order Modeling
Publisher: ASCE
Abstract: Aeroelastic instability and buffeting are two wind-induced phenomena for long-span bridges. In the traditional method, aeroelastic instability and buffeting are analyzed separately. If geometric and aerodynamic nonlinearity ...
Aerostatic Stability and Bifurcation for Long-Span Bridges Based on Reduced Order Modeling via Singular Value Decomposition
Publisher: American Society of Civil Engineers
Abstract: The traditional nonlinear aerostatic instability of long-span bridges is based on a two-layer iteration method that accurately predicts the structural equilibrium path before the critical buckling point. Due to strong ...
Process Simulation and Mesoscopic Analysis of Rockfill Dam Compaction Using Discrete Element Method
Publisher: ASCE
Abstract: To investigate the mesoscopic mechanism of rockfill dam material compaction, the discrete element method is used to simulate the entire compaction process. An irregular aggregate model is first established using laser ...
