RISWind Loads on Low-Profile, Tilted, Solar Arrays Placed on Large, Flat, Low-Rise Building Roofs
Publisher: American Society of Civil Engineers
Abstract: The author examined wind loads on low-profile, roof-mounted solar arrays, placed on large, low-rise buildings with nearly flat roofs by using scale models in a boundary layer wind tunnel. The author also examined the effects ...
Comparisons 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 ...
Database-Assisted Design of Low-Rise Buildings: Aerodynamic Considerations for a Practical Interpolation Scheme
Publisher: American Society of Civil Engineers
Abstract: Database-assisted design (DAD) is becoming a realistic possibility whereby archived wind pressure time series on building envelopes from wind tunnel experiments are directly used in structural analysis software for building ...
Glass Breakage Tests under Fluctuating Wind Loads
Publisher: American Society of Civil Engineers
Abstract: The current North American design codes for wind loads have dealt with the unique characteristics of glass using the observed failure mechanism of static fatigue, which is based on the concept of damage accumulation as ...
Examination of Load Resistance in Window Glass Design
Publisher: American Society of Civil Engineers
Abstract: The glass failure prediction model has been used as a calculation method for the load resistance (LR) of glass specified in North American design codes. However, because of the technology available, this model has only ...
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 ...
Storm and Gust Duration Effects on Design Wind Loads for Glass
Publisher: American Society of Civil Engineers
Abstract: Duration effects on the design wind loads for glass are examined with respect to ASCE 7-10. Pressure time histories are created by combining variations of wind speed and wind direction from a “design cyclone” with pressure ...
Effects of Pressure Equalization on the Performance of Residential Wall Systems under Extreme Wind Loads
Publisher: American Society of Civil Engineers
Abstract: During strong windstorms, sheathing and siding on residential, wood-framed, wall systems have commonly failed. In the current study, a clear difference is observed in the rate of failure occurrence for wall sheathing above ...
Fragility Assessment of Roof-to-Wall Connection Failures for Wood-Frame Houses in High Winds
Publisher: American Society of Civil Engineers
Abstract: The enhanced-Fujita scale (EF-scale) is used to identify tornado intensity. It uses several damage indicators (DIs), each of which has descriptions of the degrees-of-damage (DOD) along with associated wind speeds. Recent ...
Evaluation of Quasi-Steady Theory Applied to Windborne Flat Plates in Uniform Flow
Publisher: American Society of Civil Engineers
Abstract: This paper analyzes models based on the quasi-steady theory for the flight of windborne plate debris. It is shown that the effects of the rotational lift, drag, and pitching moment are important and are included in the ...
