This book was released on 2017 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: Protection of bridges from blast load due to terrorist attacks or accidental explosions is necessary. For this we require to study the performance of a bridge when blast loads are applied above the deck slab. The research presented in this thesis represents the response of AASHTO type VI girders of a bridge subjected to blast loading. This research focusses on the material properties by varying the strength concrete i.e. 6 ksi (41.4 MPa) and 15 ksi (103.42 MPa) and structural point of view by varying the point of application of blast load i.e. above the pier and at mid-span. For this work CSI Bridge software has been used for developing the model, applying blast load and analyzing results. The bridge model used for this experiment has been designed in accordance with “AASHTO LRFD Bridge Design Specifications (Second Edition, 1998, including interims for 1999 through 2002)”. The blast load has been applied in three different levels i.e. high level, medium level and low level. The blast pressure on each element due to different levels of blast load is calculated in accordance with “Unified Facilities Criteria - Structures to Resist the Effects of Accidental Explosions” (UFC 3-340-02). The blast pressure has been applied on each element with the help of a time history function. The experimental results studied were end moments of each girder, a maximum moment in each girder and maximum deflection in each case. Some conclusions were drawn out after comparing the obtained results with allowable limits of moment and deflection.
Book Synopsis Blast/explosion Resistant Analysis of Composite Steel Girder Bridge System by : Fang Zhou
Download or read book Blast/explosion Resistant Analysis of Composite Steel Girder Bridge System written by Fang Zhou and published by . This book was released on 2009 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design of bridge structures to resist explosive loads has become more of a concern to the engineering community. This thesis proposes a method to evaluate the effects of conventional blast loads on a two span continuous composite steel girder bridge system. The bridge design is based on AASHTO LRFD method. Resistance capacities of bridge deck and composite steel girder are calculated according to AASHTO specifications. Equivalent blast pressures on the bridge components are obtained. Response and performance of concrete deck, steel girders, and supporting piers are evaluated under typical blast loads. The blast induced force in the bridge components are computed in the static analyses for varying amounts of TNT. The blast effects in the supporting pier are determined using both static and dynamic analyses. Further research needs to be done in the dynamic analysis of the bridge system subjected to blast loads.

Book Synopsis Assessment of Prestressed Reinforced Concrete Box Girder Bridges Under Blast Loads by : Ahmed Abdel Rahman A. Ibrahim
Download or read book Assessment of Prestressed Reinforced Concrete Box Girder Bridges Under Blast Loads written by Ahmed Abdel Rahman A. Ibrahim and published by . This book was released on 2010 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Significant research has been performed on the response and retrofit of buildings under blast loads. Limited research exists on the response prediction and protection of bridges under near-field blast loads. This research focuses on the evaluation of box girder bridges under blast loads. The objective of this research is to develop analytical and numerical models to predict the damage level in a concrete deck under blast loading and the corresponding dynamic response of the damaged bridge system. The numerical analysis starts from the verification of blast pressure in the free air using explicit LS-DYNA with the Arbitrary Lagrangian Eulerian (ALE) system of equations, followed by predicting the damage level on concrete panels under different charge weights and standoff distances and finally evaluating the dynamic response of bridge superstructure using the predominant damage levels. In addition, an analytical formulation will be presented to predict damage level of concrete structures under blast loading. Key parameters were studied during the analysis, such as the weight of the charge, the standoff distance, and concrete deck properties. Preliminary simulation results compared well with existing experimental blast test data on concrete panels for predicting the damage level. Simple analytical models for predicting the spalling/breaching of concrete walls under blast are development and will be refined using the numerical parametric study. An Artificial Network model (ANN) for predicting the concrete damage under near field blasts is also developed based numerical simulations of 125 slab blast configurations. The results compared reasonable well with existing empirical methods.

Available in PDF, EPUB and Kindle. Book excerpt: The successful design and construction of iconic new buildings relies on a range of advanced technologies, in particular on advanced modelling techniques. In response to the increasingly complex buildings demanded by clients and architects, structural engineers have developed a range of sophisticated modelling software to carry out the necessary structural analysis and design work. Advanced Modelling Techniques in Structural Design introduces numerical analysis methods to both students and design practitioners. It illustrates the modelling techniques used to solve structural design problems, covering most of the issues that an engineer might face, including lateral stability design of tall buildings; earthquake; progressive collapse; fire, blast and vibration analysis; non-linear geometric analysis and buckling analysis . Resolution of these design problems are demonstrated using a range of prestigious projects around the world, including the Buji Khalifa; Willis Towers; Taipei 101; the Gherkin; Millennium Bridge; Millau viaduct and the Forth Bridge, illustrating the practical steps required to begin a modelling exercise and showing how to select appropriate software tools to address specific design problems.
