RISComparisons of Aerodynamic Data with the Main Wind Force–Resisting System Provisions of ASCE 7-16. I: Low-Rise Buildings
Publisher: ASCE
Abstract: This study assesses the wind load provisions for low-rise buildings with Chapters 27 and 28 in ASCE 7-16 and analyzes the dependence of the aerodynamics on the building geometric parameters. A systematic analysis of an ...

Comparisons of Aerodynamic Data with the Main Wind Force–Resisting System Provisions of ASCE 7-16. II: Mid- and High-Rise Buildings
Publisher: ASCE
Abstract: The purpose of this study is to investigate the effects of building geometry on tall-building aerodynamics, accompanying the analysis for low-rise buildings found in the companion paper. Aerodynamic data for total of 30 ...
Smart Meter Analytics to Pinpoint Opportunities for Reducing Household Water Use
Publisher: American Society of Civil Engineers
Abstract: Knowledge of when, how, and by whom water is being used is crucial for planning ways to conserve drinking water. The goal of this paper is to identify groups of similar households (whom) based on their regular high-magnitude ...
Improve Sight Distance at Signalized Ramp Terminals of Partial-Cloverleaf Interchanges to Deter Wrong-Way Entries
Publisher: American Society of Civil Engineers
Abstract: Providing drivers with open sight distance on entrance ramps can help prevent wrong-way entries at interchange terminals. For partial-cloverleaf (parclo) interchange terminals with close-spaced two-way ramps, appropriate ...
Finite-Element Modeling of Concrete-Filled Steel Tubular Columns under Axial Compression
Publisher: American Society of Civil Engineers
Abstract: Concrete-filled steel tubular (CFST) structures involve pouring concrete into steel tubes, which exert a constraining role, significantly enhancing the ductility of the concrete. Such structures are gaining popularity in ...
Direct Adaptive Control Scheme for a Quadrotor Helicopter with Actuator Failures via Quantum Logic
Publisher: American Society of Civil Engineers
Abstract: This study considers the attitude control problems of a quadrotor helicopter with actuator failures and external disturbance and thus proposes a self-repairing control scheme via adaptive control and quantum logic. An ...

Influence of Different Rim Widths and Blowing Ratios on Film Cooling Characteristics for a Blade Tip
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Three-dimensional simulations of the squealer tip on the GE-E3 blade with eight film cooling holes were carried out. The effect of the rim width and the blowing ratio on the blade tip flow ...
Shear Behavior of Soil–Rock Mixture Composed of Diorite-Porphyrite Considering Weathering Sequence
Publisher: ASCE
Abstract: Due to the weathering process, diorite-porphyrite dikes break up into a soil–rock mixture (SRM), which is crucial to the stability of dams and reservoirs that are under frequent fluctuations of water level. However, the ...
