RISGlass 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 ...
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 ...
A New Delayed Resonator Design Approach for Extended Operable Frequency Range
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The operable frequency range of the delayed resonators (DR) is known to be narrow due to stability issues. This study presents a novel approach for DR design with a combined feedback strategy that consists of a delayed ...
Novel Piston-Type Synthetic Jet Actuator with Auxiliary Air Inlet
Publisher: American Society of Civil Engineers
Abstract: A novel piston-type synthetic jet actuator (SJA) is developed which has an auxiliary air inlet close to bottom dead center (BDC) to alleviate the difficulty during suction duration. The flow characteristics of the novel ...
Sea Ice Motion Vector Retrievals from AMSR2 89-GHz Data: Validation Algorithm with Simultaneous Multichannel Observations
Publisher: American Meteorological Society
Abstract: In retrievals of sea ice motion vectors (SIMVs) based on passive microwave observations, the use of the high-resolution 89-GHz channel of the Advanced Microwave Scanning Radiometer 2 (AMSR2) has the advantage of enhancing ...
Uncertainties in the Estimation of Local Peak Pressures on Low-Rise Buildings by Using the Gumbel Distribution Fitting Approach
Publisher: American Society of Civil Engineers
Abstract: The lack of a standard accepted method to estimate local peak pressure coefficients from wind tunnel data can lead to inconsistent definitions and interpretations, particularly because cost and time constraints associated ...
Composite Deck Having Transverse Stiffeners Bonded with a Cementitious Adhesive Subjected to Moving-Wheel Fatigue
Publisher: American Society of Civil Engineers
Abstract: This paper presents the behavior of a new composite deck system for twin-girder bridges subjected to moving-wheel fatigue load. The one-half scale system consists of a RC slab with transverse rib stiffeners welded to steel ...
