Performance Prediction of a Sub-Slab Heat Exchanger for Geothermal Heat Pumps
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A large portion of the installation cost of a ground-coupled heat pump system is for the excavation necessary for ground coil placement. One possible method of reducing this cost is to place ...
Sensitivity of Load Distribution in Light-Framed Wood Roof Systems due to Typical Modeling Parameters
Publisher: American Society of Civil Engineers
Abstract: Because failure of roof systems in past high wind events has demonstrated the consequences of not maintaining a continuous load path from the roof to the foundation, many studies have been conducted to better understand ...
Seismic Performance Assessment of Simply Supported and Continuous Multispan Concrete Girder Highway Bridges
Publisher: American Society of Civil Engineers
Abstract: Seismic evaluations of typical concrete girder bridges are conducted for both a multispan simply supported and a multispan continuous girder bridge common to the Central and Southeastern United States. These evaluations ...
Scaling Bias and Record Selection for Quantifying Seismic Structural Demand
Publisher: American Society of Civil Engineers
Abstract: Lack of sufficient earthquake records for a given site and hazard level is a frequent challenge in seismic response assessment. This paper considers the response of several simple nonlinear systems to “amplitude-scaled” ...
Behavior of Light-Framed Wood Roof-to-Wall Connectors Using Aged Lumber and Multiple Connection Mechanisms
Publisher: American Society of Civil Engineers
Abstract: Ensuring a complete load path in light-framed wood structures is critical in providing proper load transfer during wind and seismic events. Roof-to-wall metal-connectors are often used to accomplish this goal. Currently, ...
Bridge Damage and Repair Costs from Hurricane Katrina
Publisher: American Society of Civil Engineers
Abstract: Hurricane Katrina caused significant damage to the transportation system in the Gulf Coast region. The overall cost to repair or replace the bridges damaged during the hurricane is estimated at over $1 billion. This paper ...
Applications of a New Handheld Reference Point Indentation Instrument Measuring Bone Material Strength
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A novel, handheld Reference Point Indentation (RPI) instrument, measures how well the bone of living patients and large animals resists indentation. The results presented here are reported in terms of Bone Material Strength, ...
