Direct Strength Prediction Of Cold-Formed Steel Beam-Columns, American Iron And Steel Institute

American Iron and Steel Institute (AISI) Specifications, Standards, Manuals and Research Reports (1946 - present)

The Direct Strength Method (DSM) of cold-formed steel member design employs local, distortional, and global cross-section elastic buckling analysis with empirically derived “direct” expressions to predict member strength. DSM is an accepted design method in national design specifications (e.g., AISI-S100-16) and enables a unified, robust, and flexible design approach. However, for beam-columns DSM in current design specifications employs simplified linear interaction expressions based on combining the isolated axial and bending elastic buckling and strength response. Today, local, distortional, and global elastic buckling under any combination of axial load and bending moments may be found using elastic buckling analysis tools such …

Climate Change And The Delta, San Francisco Estuary And Watershed Science, Michael D. Dettinger, Jamie Anderson, Michael L. Anderson, Larry R. Brown, Daniel R. Cayan, Edwin P. Maurer

Civil, Environmental and Sustainable Engineering

Anthropogenic climate change amounts to a rapidly approaching, “new” stressor in the Sacramento–San Joaquin Delta system. In response to California’s extreme natural hydroclimatic variability, complex water-management systems have been developed, even as the Delta’s natural ecosystems have been largely devastated. Climate change is projected to challenge these management and ecological systems in different ways that are characterized by different levels of uncertainty. For example, there is high certainty that climate will warm by about 2°C more (than late-20th-century averages) by mid-century and about 4°C by end of century, if greenhouse-gas emissions continue their current rates of acceleration. Future precipitation changes …

Exploring Length-Based Vehicle Count Data, Byad Ahmed

Civil and Environmental Engineering Master's Project Reports

The development of Intelligent Transportation Systems (ITS) requires high-quality traffic information within most urban areas worldwide, and under growing pressure for improving traffic management, there has been an increasing urge to collecting and monitoring of traffic data. One of the most reliable and recommended technology for drive thru or traffic control is the loop vehicle detection system. On the Portland freeway system, new software has been installed that allows the reporting of vehicle length in bins. This research investigates the use of this data (length based) by exploring time series analyses of the vehicle counts as freight and non-freight movement.

Elastic Field And Frequency Variation In Extendable Wind Turbine Blades, Jeswin John, Donald W. Radford, Subhas Karan Venayagamoorthy, Paul R. Heyliger

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The behaviors of tip displacement, maximum stress, and natural frequency of vibration as a function of blade length are investigated for extendable wind turbine blades. A three-dimensional linear elasticity finite-element model of the blade is used along with a typical profile and representative material properties. The quasi-linear response and free vibration behavior are investigated for a sequence of blade geometries. These estimates are intended to give approximate measures of expected changes in the elastic and dynamic field as the operating length changes and provide preliminary guidelines for this novel class of structure.

Restoring Capacity In Compromised Glued Laminated Beams, Cole Moller

Graduate Theses & Non-Theses

After structural fires are extinguished, presuming the structure is not a total loss, structural wood members can be inspected for residual properties. Through this research, we explored alternative methods aimed at keeping structurally compromised wood member’s in service when they would otherwise warrant replacement. For this study, we used 24F-V8 DF/DF glued laminated beams that had been loaded to their max capacity; both non-fire damaged and fire damaged. In situations where physical and mechanical changes occur, and the beam warrants individual replacement, a new restoration procedure could be used to salvage the member. Salvaging the member could mean to keep …

Evaluation Of Slope Stability Quantifying The Effect Of Vegetation, Roberto José Marín, Juan Pablo Osorio

Conference papers

The present study evaluates the shallow landslides susceptibility triggered by rainfall by means of multiple numerical simulations. The simulations integrate a transient rainfall infiltration model with an infinite slope stability model, both of them developed for unsaturated soils in a basin scale. TRIGRS’ infiltration model is used to calculate pore water pressure. The geotechnical model includes the evaluation of two parameters related to vegetation: root reinforcement and tree surcharge due to the weight of the vegetation. These simulations were carried out using multiple values of these parameters so that their behavior is analyzed for the topographic conditions of the watershed …

Changing Trends In Wave Heights In The U.S. Mid-Atlantic Region, Hillary Lane

Civil & Environmental Engineering Theses & Dissertations

The pace and effects of climate change are an area of constant focus for coastal engineers as evolving patterns in the atmosphere worldwide affect the oceans and coasts on a regional and global scale. Surface waves respond to changing wind patterns both locally and from propagating swell, and the difficulty in predicting future wind patterns is well-established. Expectations that climate change will result in more frequent and intense coastal storms and consequently greater wave heights in the North Atlantic are still unrealized, and recent forecasts from a variety of atmosphere-ocean coupled global climate models instead predict decreasing wave heights through …

Effects Of Surrounding Water Table On A Forested Wetland Habitat In East Coast Of Virginia, Lane Stokes

Civil & Environmental Engineering Theses & Dissertations

Exchanges into and out of a wetland, including surface water flow, groundwater flow, and constituents in the flows, usually determine the wetland physicochemical characteristics and biodiversity. To date, of these three exchanges, groundwater flow is the least studied, particularly in the United States of America. In this thesis, field observations were conducted at a forested non-tidal wetland, located on a flat hilltop. The position of the wetland is such that groundwater outflow is the only significant exchange that could be impacted by the surrounding land use. In addition, a spatially variable steady-state model was set up to extrapolate the observations …
