Abstract:: Current AASHTO-LRFD specifications use many disparate design provisions to establish live load demands in bridge decks. As an example, approximately 17% of Chapter 4 addresses the analysis of decks. One of the AASHTO-LRFD analysis methods for decks uses an orthotropic plate model. The present AASHTO-LRFD orthotropic plate model has a...

Abstract:: Measures to prevent progressive collapse of structures include protection of critical elements such as columns. In support of this goal, nine tests were conducted to assess the as-built performance of typical columns and the effectiveness of carbon fiber jackets in improving their performance. A quasi-static load protocol was developed to...

Abstract:: A numerical investigation is presented on effects of plan configuration on seismic responses of single-story, wood-frame dwellings. 151 models were developed using observations of 412 dwellings of rectangular, L, T, U, and Z-shapes in Oregon. A nonlinear, time-history program, Seismic Analysis Package for Wood-frame Structures, was the analysis platform. Models...

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...

Creator:: Leon, Arturo S., Kanashiro, Elizabeth A., and González-Castro, Juan A.
Abstract:: We present a new model for unsteady flow routing through dendritic and looped river networks based on performance graphs. The model builds upon the application of Hydraulic Performance Graph (HPG) to unsteady flow routing introduced by Gonzalez-Castro (2000) and adopts the Volume Performance Graph (VPG) introduced by Hoy and Schmidt...

Abstract:: The model presented herein is the same as that of Leon et al. (2010b), except that it has been modified to preserve "lake at rest" conditions in sloped prismatic conduits. The results of the new model (present paper) are identical to those of Leon et al. (2010b) for non-rest conditions....

Abstract:: After the collapse of the I35W Bridge in Minneapolis, MN in 2007, transportation agencies began evaluating and rating their inventories of gusset plate connections. Connection evaluations require accurate drawings that detail the plate, member, and fastener geometries. These structural details should also accurately reflect the as-built conditions. For some connections,...

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...

Abstract:: Previous research has found that distracted driving measurably increases driver response times to unanticipated roadway hazards. These instances are of particular consequence as they tend to be highly correlated with vehicle crashes resulting in property damage and/or injury. However, comparatively little attention has been allocated to quantifying the negative impacts...
