Nonlinear Concrete Behaviour, Marian Sabau, Traian Onet Nov 2011

Nonlinear Concrete Behaviour, Marian Sabau, Traian Onet

Marian Sabau

This paper presents an overview of nonlinear behaviour in reinforced concrete structures. Structural concrete is a nonlinear material both at strength limit states and service loads. Are presented terms of effects that are primarily observed in concrete, steel or a combination of the two. When considering nonlinear behaviour, an important aspect is whether or not strain localization will occur as size effects. The model must first be validated by experiments and benchmark tests to ensure the safety and reliability criteria. In nonlinear finite element procedures, engineers must check their finite element discretization and modelling assumptions used in their analyses. Advanced …

Comparison Of Design-Build And Design-Bid-Build Performance Of Public University Projects, James David Fernane Aug 2011

Comparison Of Design-Build And Design-Bid-Build Performance Of Public University Projects, James David Fernane

UNLV Theses, Dissertations, Professional Papers, and Capstones

With an unsure market and scarce work, owners across the United States, especially universities, are finding themselves in situations where they are unable to complete their projects within cost and schedule using the traditional delivery method: Design-Bid-Build (DBB). Under the DBB project delivery method, many competent contractors are electing to send low bids on projects just to keep work on their books, with plans to receive change orders once the project is underway; this practice is leading to cost and schedule overruns. Public universities across the United States are beginning to elect to use Design-Build (DB) as an alternate project …

The Impacts Of Road Capacity Removal, Jason E. Billings May 2011

The Impacts Of Road Capacity Removal, Jason E. Billings

Master's Theses

The road infrastructure of North America is aging, and many governments are faced with a critical decision: do we repair or remove freeways from our urban centers? Freeway repair is exceptionally expensive, but removing a freeway is widely seen as a risky venture which may result in negative traffic effects. Therefore, it is necessary to gain a clearer understanding of how removing road capacity effects traffic distribution. Three freeway segments were ultimately selected for case study analysis: two in San Francisco and one in Milwaukee. This analysis consisted of identifying changes in the traffic volumes and volume-capacity (V/C) ratios in …

Methodology To Convert A Transportation Planning Origin-Destination Matrix Into A Microscopic Traffic Simulation Origin-Destination Matrix, Jose Osiris Vidana-Bencomo Jan 2011

Methodology To Convert A Transportation Planning Origin-Destination Matrix Into A Microscopic Traffic Simulation Origin-Destination Matrix, Jose Osiris Vidana-Bencomo

Open Access Theses & Dissertations

Microscopic traffic simulation (MTS) is a cost-effective approach for the evaluation of traffic conditions in urban highways networks. In MTS models, traffic demand that is entered into the network is specified by one or several Origin-Destination (O-D) matrices. A major challenge in the application of MTS for large urban networks is the specification of the O-D matrices. This dissertation proposes a methodology that may be used to transform a O-D matrix from a transportation planning model (which is based on Traffic Analysis Zone, or TAZ, and is readily available) into a O-D matrix for a MTS model (which is traffic …

A Financial Impact Assessment Of Ld 1725: Stream Crossings Presentation, New England Environmental Finance Center Jan 2011

A Financial Impact Assessment Of Ld 1725: Stream Crossings Presentation, New England Environmental Finance Center

Economics and Finance

This report looks at the potential financial impact of LD 1725 on the estimated 30,000 stream crossings in the State of Maine that would be affected by the law. Our research for this report included the analysis of nearly 2000 stream crossings and the data collection necessary for the development of extensive stream crossing replacement cost models. We found that the 1.2 bankfull requirements in LD 1725 would result in a 75% ‐ 250% increase in structure widths for stream crossing projects across the state. An upsize of this magnitude would increase the cost of replacing stream crossings statewide by …
