Bridge Engineering Automated Vehicle Application

The general philosophy governing the design of bridges is that, subject to a set of loading rules and constraints, the worst effects due to load application should be established and designed against. The process of load application can be complex as governing rules can impose interdependant parameters such as loaded length on a lane, lane factors and load intensity. To obtain the maximum design effects, Engineers have to try many loading situations on a trial and error basis. This leads to the generation of many live loadapplication instances and a large volume of output data that has to be combined with dead load effects as well. In view of the above, a computer program has been developed to minimise the load application process while complying with national code requirements. Users can avoid the trial and error approach and eliminate any possible errors arising from inaccuracies associated with it. The program is based on the use of influence surfaces, which are generated by STAAD.Pro as part of the loading process. An influence surface for a given effect on a bridge deck relates its value to movement of a unit load over the area of interest. The influence surface is a three dimensional form of an influence line for a single member. STAAD.Pro will automatically generate influence surfaces for effects such as bending moments for elements, deflection in all the degrees of freedom of nodes and support reactions. The engineer will then instruct the program to utilise the relevant influence surfaces and, with due regards to code requirements, optimise loadpositions to obtain the maximum desired effects. Once the influence surfaces have been generated, they are saved and can be used for any further investigation that may be required. This will remain valid as long as the user has not altered the structural model. Changes to the structural model can alter the pattern of the influence surfaces and the user must ensure that a further run takes place before any further processing.  The Engineers knowledge and judgement is critical in deciding which effects are required and at what position to obtain them. This is where users can save a lot of processing time and also, can ensure critical positions are not missed.

Application of Precast Decks and Other Elements to Bridge Structures

Author: Bell II, Charles M French, Catherine E Shield, Carol K | Size: 6.29 MB | Format: PDF | Quality: Original preprint | Publisher: University of Minnesota, Twin Cities | Year: 2006 | pages: 271

A number of countries have incorporated precast components in bridge superstructures and substructures. Precast components include deck, abutment, and wall elements. Benefits of using precast elements in bridge construction include the high level of quality control that can be achieved in plant cast production compared to field cast operations and speed of construction afforded by the assembly of precast elements at the site rather than the time consuming on site forming and casting required in cast-in-place construction. Key components in the application of precast concrete to bridge structures are the connection elements. Connection details include the use of posttensioning systems, and various connection details such as weld plates, studs in grout pockets, and shear keys. The Minnesota Department of Transportation (Mn/DOT) constructed a bridge incorporating precast elements to enable rapid construction. The objective of this study was to develop an instrumentation plan to enable investigation of the performance of this bridge. Researchers developed an instrumentation plan based on information provided by the Mn/DOT bridge office regarding the specific bridge details and behaviors to be investigated. The instrumentation plan included the types and locations of the instruments.

Bridge Aeroelasticity: Sensitivity Analysis and Optimum Design (High Performance Structures and Materials)

 

Author: J.A. Jurado (Author), S. Hernandez (Author), F. Nieto (Author) | Size: 34.50 MB | Format: PDF | Publisher: WITPress / Computational Mechanics | Year: 2011 | pages: 368 | ISBN: ISBN10: 184564056X & ISBN13: 9781845640569

This book is dedicated to the study of an aeroelastic phenomenon of cable-supported long-span bridges known as flutter, and proposes very innovative design methodologies, such as sensitivity analysis and optimization techniques, already utilized successfully in automobile and aerospace industries.

The topic of long-span suspension and cable-stayed bridges is currently of great importance. These types of bridge pose greattechnical difficulties due to their slenderness and often great dimension. Therefore, these bridges tend to have problems caused by natural forces such as wind loads, some of which we have witnessed in our history, and we are currently seeing a very high incidence of bridge construction to overcome geographical obstacles such as bays, straits, or great estuaries. Therefore, it seems very appropriate to write a book showing the current capability of analysis and design, when up until now, the information could only be found partially in technical articles.

This book will be useful for bridge design engineers as well as researchers working in the field. This book only requires previous knowledge of structural finite element models and dynamics, and it is advisable to have some previous knowledge in bridge engineering. Nevertheless, this book is very self-contained in such a way that all the information necessary to understand the theoretical developments is presented without the need of additional bibliography.

Computer Aided Analysis and Design of Multi-Storeyed Buildings

The principle objective of this project is to analysis and design a multi-storeyed building [G + 21 (3 dimensional frame)] using STAADPro. The design involves load calculations manually and analyzing the whole structure by STAAD Pro. The design methods used inSTAAD-Pro analysis are Limit State Design conforming to Indian Standard Code of Practice. STAAD.Pro features a state-of-the-art user interface, visualization tools, powerful analysis and design engines with advanced finite element and dynamic analysis capabilities. From model generation, analysis and design to visualization and result verification, STAAD.Pro is the professional’s choice. Initially we started with the analysis of simple 2 dimensional frames and manually checked the accuracy of the software with our results. The results proved to be very accurate. We analysed and designed a G + 7 storey building [2-D Frame] initially for all possible load combinations [dead, live, wind and seismic loads].
 

STAAD.Pro has a very interactive user interface which allows the users to draw the frame and input the load values and dimensions. Then according to the specified criteria assigned it analyses the structure and designs the members with reinforcement details for RCC frames. We continued with our work with some more multi-storeyed 2-D and 3-D frames under various load combinations. Our final work was the proper analysis and design of a G + 21 3-D RCC frame under various load combinations.
 

We considered a 3-D RCC frame with the dimensions of 4 bays @5m in x-axis and 3 bays @5m in z-axis. The y-axis consisted of G + 21 floors. The total numbers of beams in each floor were 28 and the numbers of columns were 16. The ground floor height was 4m and rest of the 21 floors had a height of 3.3m.The structure was subjected to self weight, dead load, live load, wind load and seismic loads under the load case details of STAAD.Pro. The wind load values were generated by STAAD.Pro considering the given wind intensities at different heights and strictly abiding by the specifications of IS 875. Seismic load calculations were done following IS 1893-2000. The materials were specified and cross-sections of the beam and column members were assigned. The supports at the base of the structure were also specified as fixed. The codes of practise to be followed were also specified for design purpose with other important details. Then STAAD.Pro was used to analyse the structure and design the members. In the post-processing mode, after completion of the design, we can work on the structure and study the bending moment and shear force values with the generated diagrams. We may also check the deflection of various members under the given loading combinations. The design of the building is dependent upon the minimum requirements as prescribed in the Indian Standard Codes. The minimum requirements pertaining to the structural safety of buildings are being covered by way of laying down minimum design loads which have to be assumed for dead loads, imposed loads, and other external loads, the structure would be required to bear. Strict conformity to loading standards recommended in this code, it is hoped, will ensure the structural safety of the buildings which are being designed. Structure and structural elements were normally designed by Limit State Method.
 

Complicated and high-rise structures need very time taking and cumbersome calculations using conventional manual methods.STAAD.Pro provides us a fast, efficient, easy to use and accurate platform for analysing and designing structures.
