Available in PDF, EPUB and Kindle. Book excerpt: The Proceedings of the NATO Advanced Study Institute on Analysis and Design of Bridges held at ~e§me, lzmir, Turkey from 28 June 1982 to 9 July 1982 are contained in the present volume. The Advanced Study Institute was attended by 37 lecturers and participants from 10 different countries. The Organizing Committee consisted of Professors P. Gtilkan, A. C. Scordelis, S. T. Wasti and 9. Yl. lmaz. The guidelines set by NATO for the Advanced Study Institute require it to serve not only as an efficient forum for the dissemination of available advanced knowledge to a selected group of qualified people but also as a platform for the exploration of future research possibilities in the scientific or engineering areas concerned. The main topics covered by the present Advanced Study Institute were the mathematical modelling of bridges for better analysis and the scientific assessment of bridge behaviour for the introduction of improved design procedures. It has been our observation that as a result of the range and depth of the lectures presented and the many informal discussions that took place, ideas became fissile, the stimulus never flagged and many gaps in the engineering knowledge of the participants were "bridged". Here we particularly wish to mention that valuable informal presenta tions of research work were made during the course of the Institute by Drs. Friedrich, Karaesmen, Lamas and Parker.

This book was released on 1993 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: A layered finite element model with material nonlinearity is developed to trace the nonlinear response of horizontally curved reinforced concrete box-girder bridges. Concrete is treated as an orthotropic nonlinear material and reinforcement is modeled as an elastoplastic strain-hardening material. Due to the fact that the flanges and webs of the structure are much different both in configuration and in the state of stresses, two types of facet shell elements, namely, the triangular generalized conforming element and the rectangular nonconforming element, are adopted to model them separately. A numerical example of a multi-cell box-girder bridge is given and the results are compared favourably with the experimental results previously obtained.

Available in PDF, EPUB and Kindle. Book excerpt: The analysis of highway bridges such as slab-on-girder bridges, box-girder bridges, cable-stayed bridges etc. is a very complicated undertaking. Analytical methods are applicable only for the simplest structures. Finite element method is the most powerful and versatile tool, which can be applied to analyze any types of bridge and any load cases. However, the efficiency of that method needs to be improved because the finite element solutions usually require too much computer time, too large core storage and too many input data.

Available in PDF, EPUB and Kindle. Book excerpt: "A splayed girder bridge is a bridge which consists of a deck slab supported on girders with linearly varying spacing. The simple formulas and approximate design procedures in the AASHTO LRFD Bridge Design Specifications are supposed to be used with regular bridges, where the girders are parallel and the deck slab width is constant. For splayed girder bridges, the specifications suggest a refined method of analysis, which could be expensive and time-consuming. Extending the simple live load girder distribution factors and the deck slab strip method to splayed girder bridges would be very helpful for bridge designers. The objective of this research is to investigate the effect of girder splayedness in slab-on-steel-girder bridges on the dead and live load distribution in the deck slab as well as among the interior and exterior girders. Fifteen composite steel girder bridges are analyzed by the finite element method using the computer software ANSYS. In the computer model, 4-node rectangular shell elements were used for the steel girder flanges and web, 2-node beam elements for the cross-bracing, and 8-node solid elements in the deck slab. Linearly-elastic material behavior is utilized and the model is verified against laboratory and field tests of actual bridges. The effects of the girder splayedness angle, girder spacing, number of girders, deck slab thickness, span length, girder stiffness, and presence of cross-bracing are considered. The study showed that the tributary width concept is reliable for determining the dead load on the splayed girders. Also, the girder distribution factors for flexure in the AASHTO LRFD specifications can be reasonably used for splayed girder bridges if the specific girder spacing at the location of each axle of the truck in the longitudinal direction is considered. On the other hand, the lever rule can provide a good estimate of the live load distribution among splayed girders when subjected to shear. With regard to the live and dead load effect in the deck slab, the equivalent strip method can be a reasonable predictor of the critical positive and negative bending moments in the slab interior regions and in the overhang, provided more than one strip are taken at some discrete locations along the bridge centerline.

This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The inability to accurately predict the non-composite steel girder deflections that occur during the deck construction of skewed and stage-constructed bridges is a problem that has resulted in many costly construction delays and maintenance and safety issues for the North Carolina Department of Transportation (NCDOT). In an effort to correct these problems, NCDOT has funded this research (Project Number 2004-14) that involves developing a simplified method of more accurately predicting the non-composite deflections of steel plate girder bridges. This study involved quantifying the inability to accurately predict the non-composite deflections of steel plate girders by measuring the deflections for several bridges in the field as the concrete deck was placed. By measuring the deflections as they occurred, the true non-composite deflection behavior of the bridge was captured and compared to the behavior predicted by the current analysis method used in the design. The current analysis method incorporates single girder line models to predict the non-composite girder deflections without accounting for any transverse distribution of the construction dead loads through the cross-frames that connect the girders. It was concluded from this study that the current analysis method over predicts the non-composite deflections by an average of 38 percent for the interior bridge girders and an average of 6 percent for the exterior girders. In order to more accurately represent the non-composite deflection behavior, detailed three dimensional finite element models were created for each of the actual bridges measured in the field. Parameters such as bridge skew, cross-frame stiffness, stay-in-place metal deck forms, and partial composite action were considered in the development of the finite element models. These models more accurately represented the torsional behavior of the bridge girders and allowed dead loads to be distributed transversely via the cross-frames used to connect th.

This book was released on 2005 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: A bridge approach slab serves as a structural slab to bridge any void that is created by any differential settlement between the bridge structure and the approach embankment. It provides a gradual transition from the pavement into the bridge. The primary causes of approach slab failures are undermining, settlement and cracking. Undermining and settlement of the slab can be treated by either mud jacking or by pumping grout material to fill the voids beneath the slab. Transverse and longitudinal cracking leads to distress of the slab and reduces its life expectancy. Repair and rehabilitation of the system is a heavy financial burden on the state department of transportation. This dissertation aims in mitigating the causes of cracking and also location of cracks by doing a finite element analysis of the slab. The factors affecting the cracks has also been studied. This study helps prove the utility of finite element analysis for reinforced concrete structures.
Download or read book Semi Quantitative Assessment Framework for Corrosion Damaged Slab on Girder Bridge Columns Using Simplified Nonlinear Finite Element Analysis written by Amina Mohammed and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Most of existing North American bridge infrastructure is reported to be deficient. Present infrastructure management mainly relies on qualitative evaluation, where bridge safety and serviceability are judged through routine visual inspection. With the successive increase in the number of severely deficient bridges and the limited available resources, it is crucial to develop a performance-based quantitative assessment evaluation approach that enables an accurate estimation of aging bridges ultimate and seismic capacities and ensures their serviceability. Reinforcement corrosion is the main cause of most of North American concrete infrastructure deterioration. Experimental investigations prove that reinforcement corrosion results in reduction of the steel reinforcement cross sectional area, localized (or global in very extreme cases) loss of bond action, concrete spalling, loss of core concrete confinement, and structural collapse. Field observations show that damage due to reinforcement corrosion in reinforced concrete (RC) bridge columns is localized in highly affected zones by splash of deicing water. In this thesis, an innovative performance-based semi-quantitative assessment framework is developed using newly developed simplified nonlinear static and dynamic finite element analysis approaches. The framework integrates the bridge's available design and after-construction information with enhanced inspection and additional material testing as sources for accurate input data. In order to evaluate the structural performance and the capacity of the corrosion-damaged bridge columns, four nonlinear static and dynamic analysis approaches have been developed: (i) simplified nonlinear sectional analysis (NLSA) approach that presents the basis of the analysis approaches to estimate the ultimate and seismic capacities, and serviceability of bridge columns; (ii) simplified nonlinear finite element analysis (NLFEA) approach, which enables estimating the ultimate structural capacity of corrosion-damaged RC columns; (iii) simplified hybrid linear/nonlinear dynamic finite element analysis (SHDFEA) approach to evaluate the serviceability of the bridge; and, (iv) simplified non-linear seismic analysis (SNLSA) approach to evaluate the seismic capacity of the bridge columns. The four analysis approaches are verified by comprehensive comparisons with available test experimental and analytical results. The proposed semi-quantitative assessment framework suggests three thresholds for each performance measure of the evaluation limit states to be decided by the bridge management system team. Case studies are presented to show the integrity and the consistency of using the proposed assessment framework. The proposed assessment framework together with the analysis approaches provide bridge owners, practicing engineers, and management teams with simplified and accurate evaluation tools, which lead to reduce the maintenance/rehabilitation cost and provide better safety, and reduce the variation in the data collected using only traditional inspection methods.
