Book excerpt: A number of bridges designed by the AASHTO Specifications and the Ontario Highway Bridge Design Code (OHBDC) were constructed during the early nineteen eighties. The AASHTO designs for the deck slabs were based on flexural considerations and required larger amounts of reinforcement than the minimum isotropic reinforcement required by the empirical method of the Ontario Code. Fourteen bridges were load tested to compare the performance of deck slabs designed by the two different techniques and built during this period. The applied test loads were generally less than 40 percent of the calculated punching shear capacity of deck slabs, but far exceeded the factored wheel load specified by both the AASHTO Specifications and the OHBDC. Under the test loads, the slab pannels displayed no visible signs of distress. The test data and the analysis of punching shear capacities show that the amount of reinforcement has a comparatively small effect on the strength and stiffness of the slab panels and that the slabs designed by the OHBDC have adequate strength to carry heavy wheel loads from modern trucks. The major parameters affecting the strength and stiffness are slab thickness, girder type and girder spacing. The measured deflections at the centre of slab panels were found to be significantly smaller than those calculated by the conventional plate-in-flexure analysis assuming a cracked section and concrete in tension being ineffective. The effect of 'tension stiffening' in concrete is investigated in order to explain a part of this difference. For the covering abstract of the Conference see IRRD Abstract No. 807839.

Download or read book Guidelines for the Supplementary Load Testing of Bridges written by Institution of Civil Engineers (Great Britain). National Steering Committee for the Load Testing of Bridges and published by Thomas Telford. This book was released on 1998 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bridge authorities in the UK are currently facing a large programme of bridge assessment and strengthening. This has been caused, in part, by the necessity of ensuring that the European Union deadline for allowing 40-tonne lorries on to UK roads can be met. Many bridges have failed theoretical assessments and some bridge owners, frustrated by the fact that many failed structures are apparently in good condition and showing no signs of distress, have resorted to load testing their bridges to try to provide additional information. A National Steering Committee for the Load Testing of Bridges was set up to examine the role of bridge load testing as a tool for assisting the assessment process. The National Steering Committee consists of representatives from all major bridge owners including the Highways Agency, the County Surveyors Society, the London Bridges Engineering Group, Railtrack and the British Waterways Board. It also includes representatives from consulting engineers and universities and has the support of the Institution of Civil Engineers. The overall objective of the National Steering Committee was to produce authoritative guidance on load-testing techniques; which could be used by the practising engineer to determine capacities of existing bridges/structures that are safe, prudent and minimize levels of restriction to the transport infrastructure. In June 1995 the committee appointed Rendel Palmer & Tritton in association with Peter Lindsell & Associates and supported by Professors Bakht, Clark and Harding as consultants to carry out a preliminary study of all the available information on bridge load testing. They were to recommend a detailed methodology which would form the basis of a brief to consultants appointed to produce authoritative guidelines for the load testing of bridges. Their report concluded that there is a place for load testing in the evaluation of bridges and other structures and that load testing is a valid tool for bridge managers. They also concluded that there was enough information and experience available to permit safe and effective guidelines to be written. As a result of the preliminary study the National Steering Committee decided to divide the second stage work and restrict the scope of this document to guidelines for supplementary load testing. Work on proof and proving load testing is being carried out by others under the auspices of the Highways Agency. The guidelines contained in this document were not drafted in a prescriptive form, but seek to provide advice on the appropriate use of supplementary load testing as an aid to assessment by calculation. The guidelines have been written to enable engineers to determine: when it is appropriate to consider the use of supplementary load testing; the level of risk, both public safety and economic, associated with load testing; how to plan and carry out a load test including the level of expertise necessary, the appropriate loading methods and the type and quantity of instrumentation required. In addition, the document is intended to be a source of information on load testing, measuring equipment and specialist techniques that engineers can use for reference.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research was performed to develop and test a new type of full-width partial-depth precast concrete panel (PCP) deck system for Texas bridge decks that can be implemented at the bridge overhangs. Twenty-four full-scale PCP specimens with embedded wire trusses were load tested. Test variables included specimen geometry, reinforcement detailing, and fabrication technique for the welded wire trusses. Results showed that the design generally performed in a ductile and relatively well-predicted manner using static analysis techniques. Specimens tended to reach a load plateau before failure. Some specimens with longer unbraced truss lengths tended to buckle after reaching a load plateau. Specimens with lower-strength trusses tended to avoid buckling-type failures altogether. Bundling additional reinforcing bars to the bottom chord also completely prevented buckling

This book was released on 1997 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis will be of interest to state department of transportation bridge design and structural engineers, bridge consultants, and others involved in applied and research methods for increasing the live load capacity of existing highway bridges. The synthesis describes the current state of the practice for the various methods used to increase the live load capacity of existing highway bridges. This is done predominantly for bridges in the short- to medium-span range. Information on the more common bridge material types is presented. There is an emphasis on superstructure rather than substructure strengthening.

This book was released on 2002 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: There exists in the state of Ohio a large inventory of short span reinforced concrete bridges, particularly on rural secondary highways, whose actual structural reliability cannot be accurately ascertained.
