RISComparison of Reduced-Order Models to Analyze the Dynamics of a Tall Building under the Effects of Along-Wind Loading Variability
Publisher: American Society of Civil Engineers
Abstract: Aeroelastic vibration, influenced by wind load effects, is relevant to the structural design of tall buildings. In the framework of performance-based design of wind load–sensitive structures, the effects induced by variability ...
Life-Cycle Cost Analysis of a Point-Like Structure Subjected to Tornadic Wind Loads
Publisher: ASCE
Abstract: To quantify the monetary losses associated with damages induced by tornado wind storms, a numerical performance-based engineering framework complete with dynamic simulation of tornado-like wind fields, calculation of ...
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 ...
Practical Approach to Digitally Simulate Nonsynoptic Wind Velocity Profiles and Its Implications on the Response of Monopole Towers
Publisher: ASCE
Abstract: In the numerical simulation of stochastic nonstationary wind loads, rapidly varying wind speed fluctuations about a deterministic mean value typically represent the sole source of random variability. Adopted in ...
Damping of Taut-Cable Systems: Two Dampers on a Single Stay
Publisher: American Society of Civil Engineers
Abstract: The mitigation of in-plane stay oscillation in cable-stayed bridges is commonly addressed by placing an external mechanical damper, linear or nonlinear, on each stay or by introducing transverse cross-ties among cables. ...
Hydroelastic Instability of Low Aspect Ratio Control Surfaces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As the operational speeds of surface ships and submarines increase, so does the probability that unwanted vibrations caused by the hydroelastic instability (flutter) of the special class of ...
Performance-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 ...
Cost-Based Design of Nonstructural Elements for Tall Buildings under Extreme Wind Environments
Publisher: American Society of Civil Engineers
Abstract: The early stages of the design process of wind-excited tall buildings involve several decisions on structural typology, shape, orientation, optional control system, and type and distribution of nonstructural elements. ...
