A Systems Approach to Civil Engineering Decisions

Creator:: Rodriguez-Nikl, Tonatiuh and Brown, Colin B.
Abstract:: While contemporary civil engineering projects are increasingly complex, the cognitive abilities of the decision maker remain limited. There is a conflict between the complexity that is required to describe a scenario with all its relevant properties and the limited number of ideas that can be included in rational considerations and...

Effects of Roof Pitch and Gypsum Ceilings on the Behavior of Wood Roof Diaphragms

Creator:: Kirkham, William J., Gupta, Rakesh, and Miller, Thomas H.
Abstract:: Ten full size (3.7 x 4.9 m) plywood roof diaphragms were constructed using metal plate connected (MPC) common and hip wood trusses or joists, typical of single-family dwelling (SFD) construction. The specimens included three gable roof slopes of 33, 67 and 100%, a hip roof of 33% slope, and a...

Hinged, pseudo-grid triangulation method for long, near-linear cliff analyses

Creator:: Olsen, Michael J., Kuester, Falko, and Johnstone, Elizabeth
Abstract:: LIDAR scanners can rapidly collect high resolution, cm-level accurate point clouds representing topography, suitable for change detection if scans are repeated over time. To perform meaningful volumetric change analyses, point clouds are commonly triangulated to produce continuous, digital terrain models (DTMs). However, DTM creation methods generally require a fixed look...

Behavioral Thresholds in Mixtures of Sand and Kaolinite Clay

Creator:: Simpson, D. C. and Evans, T. M.
Abstract:: Nearly all soils are comprised of mixtures of coarse and fine particles. Behavior under mechanical and thermal loading of soil is strongly influenced, and in some cases governed, by the ratio of coarse to fine particles. A better understanding of the fundamental behavior of soil mixtures will provide insight to...

A Dual-Objective-Based Tornado Design Philosophy

Creator:: van de Lindt, John W., Pei, Shiling, Dao, Thang, Graettinger, Andrew, Prevatt, David O., Gupta, Rakesh, and Coulbourne, William
Abstract:: Tornadoes represent a unique natural hazard because of the very low probability of occurrence, short warning times (on the order of only a few minutes), and the intense and destructive forces imposed on engineered and non-engineered buildings. The very low-probability very high-consequence nature of a tornado strike makes designing for...

Practical Analysis for Horizontal Diaphragm Design of Wood-Frame Single-Family Dwellings

Creator:: Kirkham, William J., Miller, Thomas H., and Gupta, Rakesh
Abstract:: Seismic design of wood-frame single-family dwellings’ (WFSFD) lateral force–resisting systems requires determination of the stiffness of horizontal diaphragms and shearwalls. During design, sizes and locations of shearwall openings are often changed, altering shearwall stiffness and loads and requiring a significant redesign effort. Rigid and tributary area method analyses are examined...

Manpower pattern prediction for multi-project situations

Creator:: Olsen, Eldon D.
Abstract:: The use of logistic-type growth curves in the prediction of future engineering manpower utilization patterns is a viable technique. When a work environment consists of a large number of repetitive type project the use of regression analysis and Weibull curve shapes gives a reliable forecast of the time-phased utilization of...

Is the intensifying wave climate of the U.S. Pacific Northwest increasing flooding and erosion risk faster than sea level rise?

Creator:: Ruggiero, Peter
Abstract:: The relative contributions of sea level rise (SLR) and increasing extra-tropical storminess to the frequency with which waves attack coastal features is assessed with a simple total water level (TWL) model. For the coast of the U.S. Pacific Northwest (PNW) over the period of wave-buoy observations (~30 years) wave height...

Evaluation of Remediation Techniques for Circular Holes in the Webs of Wood I-Joists

Creator:: Polocoser, Tiberiu, Miller, Thomas H., and Gupta, Rakesh
Abstract:: Remediation methods and strength predictions were evaluated for wood I-joists with single, circular holes in the webs, leaving utilities in place. A full-scale bending test using four equally-spaced point loads was applied to three depths of joists with varying flange widths and span lengths of 4.88 m and 2.44 m....
