Air-Supported Roof Redux
Long-span, low profile, air-supported roofs have been dramatic additions to a dozen public arenas built in the 1970s and early 1980s. The advantages of these roofs were overshadowed by...
Distributed Modeling of Snowmelt and Influence of Wind
Scientific Basis of Precipitation Enhancement
What Controls the Ultimate Load of a Glulam Dome?
A glulam dome is analyzed with the finite element method to determine the governing failure mode and ultimate snow loads. The dome consists of a triangulated network of curved glulam beams,...
Experimental Study on the Strut Type of Cable Net Membrane Structures
In this paper a new type of suspension membrane structure combined with a cable net is proposed, in which the supporting struts are arranged between the membrane surface and the cable...
Atmospheric Circulation and Snowpack in the Gunnison River Basin
Winter mean 700-millibar height anomalies over the eastern North Pacific Ocean and the western United States are related to variability in snowpack accumulations measured on or about April...
On the Snow-Plough Effect when Cutting Water Saturated Sand with Inclined Straight Blades
Winter Storm Mapping a Geographic Information Systems Transportation Applications
The Winter Storm Mapping System (WSMS) has grown out of our Geographic Information System for Transportation (GIS-T). The development of this project began the spring of 1991 on the State...
Effects of Drifting on Snow Loads on Large Roofs
In areas that experience significant snow fall, snow loads typically produce the governing environmental load cases for a large span roof. Therefore for large span roofs there are considerable...
Design of Connections in Wood Structures: LRFD vs. ASD
This paper provides a comparison of connection design capacities using load and resistance factor design (LRFD) procedures and allowable stress design (ASD) procedures....
Steel Bar Joist Performance: Design Deficiencies and Defects
Several failures of steel bar joist roofs have been investigated by the authors in the past decade. Many of these failures or performance problems have corresponded to bar joists manufactured...
Snow from Recycled Wastewater is not New
A Spatial Decision Support System for Vehicle Routing
This paper describes the design, development, and implementation of a computer aided system for planning efficient network maintenance routes. The system has been used to design snow and...
Colorado Dome
Innovative engineering and precise design helped engineers overcome a building's unique shape and difficult site to deliver the $71.5 million Jefferson County Government Center...
A Revised Snowstorm Maximization Method for Canadian Boreal Regions
A proposed refinement in the development of design snowpacks for use in the derivation of probable maximum floods (PMF) estimates in the Canadian Boreal is presented. Shortcomings in the...
Snow Estimation?A GIS Application for Water Resources Forecasting
In the Western United States approximately 75 percent of the annual runoff results from snowmelt. Observations of the snow cover provide an important source of information for forecasting...
Acidity and Chemistry of Arizona's Snowpacks
Acid snow, the frozen version of the acid rain phenomena, has been sampled in several western states, e.g., California, Nevada, Montana, and Oregon. Measurements of snowpack acidity in...
Spatial and Temporal Precipitation Characteristics in Southwest Idaho
The USDA-ARS, Northwest Watershed Research Center operates a precipitation gage network on the Reynolds Creek Experimental Watershed in southwest Idaho. Analysis of the 30-yr (1962-1991)...
Getting Ahead of Snow and Ice
Winter maintenance is not the same anymore. New weather forecasting technologies are permitting snow and ice fighters to better predict when unsafe winter weather conditions will occur....
Snow and Ice Control in Japan and United States
Both Japan and the United States experience severe winter conditions that require major resources and large expenditures for maintaining highways. The maritime climate that prevails in...
