Abstract: Lognormal probability distribution functions for both ground snow loads and the ground‐to‐roof conversion factor are used to establish lognormal probability distribution functions for roof snow loads. Site specific values ...

Abstract: The response of a buried pipeline to seismic waves is controlled by differential movements along its length. The axial movement of the pipeline is restrained by friction forces at the soil-pipe interface. Tests performed ...

Abstract: A case study of damage to a welded steel pipeline in Mexico City, caused by the 1985 Michoacan earthquake, is presented. Seismic damage to pipelines in past earthquakes is briefly reviewed. The damage has typically been ...

Abstract: A database of snowdrift case histories on multilevel flat roofed structures has been established and is statistically analyzed. Drifted snow loads on multilevel roofs account for a large percentage of the roof losses in ...

Abstract: The lateral loads imposed on a structure during an earthquake are functions of the peak ground acceleration and the total mass of the structure among other parameters. For structures located in snowy regions, the question ...

Abstract: Seismic design of structures that are long in plan, such as bridges and buried pipelines, requires information on the spatial variation of ground displacements along their lengths. This variation in ground motion results ...

Abstract: Water seepage into interior spaces and the resultant staining of wall and/or ceiling surfaces is a common problem with eave ice dams. If the outdoor temperature is below freezing, the roof is poorly insulated, and if the ...

Abstract: The behavior and design of a straight buried steel pipe subject to permanent ground deformation (PGD) where the movement is parallel to the pipe axis is considered. The PGD zone is characterized by the amount of movement, ...

Abstract: This paper provides an assessment of tactile pressure sensors for geotechnical applications. A tactile pressure sensor is an array of small sensing units, called sensels, embedded in a polymeric sheet or pad that measures ...
