This book was released on 2011 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: fib Bulletin 61 is a continuation of fib Bulletin 16 (2002). Again the bulletin’s main objective is to demonstrate the application of the FIP Recommendations “Practical Design of Structural Concrete”, and especially to illustrate the use of strut-and-tie models to design discontinuity regions (D-regions) in concrete structures. Bulletin 61 presents 14 examples, most of which are existing structures built in recent years. Although some of the presented structures can be considered to be quite important and, in some instances, complex, the chosen examples are not intended to be exceptional. The main aim is to look at specific design aspects, by selecting D-regions of the presented structures that are designed and detailed according to the proposed design principles and specifications for the use of strut-and-tie models. Two papers at the end of the bulletin deal with the role of concrete tension fields in modelling with strut-and-tie models, and summarize the experiences gained by the Working Group in applying strut-and-tie models to the examples in the bulletin. It is hoped that fib Bulletin 61 will be of interest to engineers involved in the design of concrete structures, supporting the use of more consistent design and detailing tools such as strut-and-tie models.

This book was released on 2011-01-01 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: The need for housing has increased significantly during the last decades all over the world. It is felt particularly in countries where the population growth rate is high and the economy is developing fast; but everywhere people are shifting from the countryside to towns, where housing in neighbourhoods often becomes critical. The need for affordable housing may concern high-rate urbanization, rural areas to be upgraded, workers’ settlements in remote regions, rebuilding dwellings destroyed by disasters such as earthquakes, floods or wars, and even holiday resorts and leisure dwellings. Large projects always face cost- and time-constraints. Local conditions may be variable with respect to the physical, social and economic environment. Thus, minimising cost and time of construction, while maximising quantity and quality of product, may lead to different solutions. The concept of “affordable”, meaning compatibility of demand and means, is well understood as such everywhere, although its practical application may be much different from place to place. Concrete is a material that lends itself well to affordable housing: it is durable, has good thermal inertia, can be used both as structural and finishing material, and is not sensitive to organic attack. It also has some disadvantages, such as higher cost in developing countries compared to developed countries, and also a potential lack of materials, mainly cement or admixtures. Prefabrication, with its adaptability and quality consciousness, may offer valid, speedy, cost efficient and sustainable solutions. fib Bulletin 60 offers an overview of housing systems as well as information on their features. It shows the main features of a number of construction systems, without entering into the details of the solutions. It aims to make possible a comprehensive comparison, which should help in learning, exchanging and developing ideas on how to better meet the housing needs everywhere, at sustainable cost. A document of this kind was not available before; it is therefore expected to be of great interest and a source of ideas for all those who have to confront similar problems.

Available in PDF, EPUB and Kindle. Book excerpt: Strut-and-tie modeling (STM) is a versatile, lower-bound (i.e. conservative) design method for reinforced concrete structural components. Uncertainty expressed by engineers related to the implementation of existing STM code specifications as well as a growing inventory of distressed in-service bent caps exhibiting diagonal cracking was the impetus for the Texas Department of Transportation (TxDOT) to fund research project 0-5253, D-Region Strength and Serviceability Design, and the current implementation project (5-5253-01). As part of these projects, simple, accurate STM specifications were developed. This thesis acts as a guidebook for application of the proposed specifications and is intended to clarify any remaining uncertainties associated with strut-and-tie modeling. A series of five detailed design examples feature the application of the STM specifications. A brief overview of each design example is provided below. The examples are prefaced with a review of the theoretical background and fundamental design process of STM (Chapter 2). · Example 1: Five-Column Bent Cap of a Skewed Bridge - This design example serves as an introduction to the application of STM. Challenges are introduced by the bridge's skew and complicated loading pattern. A clear procedure for defining relatively complex nodal geometries is presented. · Example 2: Cantilever Bent Cap - A strut-and-tie model is developed to represent the flow of forces around a frame corner subjected to closing loads. The design and detailing of a curved-bar node at the outside of the frame corner is described. · Example 3a: Inverted-T Straddle Bent Cap (Moment Frame) - An inverted-T straddle bent cap is modeled as a component within a moment frame. Bottom-chord (ledge) loading of the inverted-T necessitates the use of local STMs to model the flow of forces through the bent cap's cross section. · Example 3b: Inverted-T Straddle Bent Cap (Simply Supported) - The inverted-T bent cap of Example 3a is designed as a member that is simply supported at the columns. · Example 4: Drilled-Shaft Footing - Three-dimensional STMs are developed to properly model the flow of forces through a deep drilled-shaft footing. Two unique load cases are considered to familiarize the designer with the development of such models.

This book was released on 2002-01-01 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 1996 FIP Recommendations Practical Design of Structural Concretewere finally published by SETO in September 1999. They had been developed based on the 1990 CEB-FIP Model Code. The main objective of this Bulletin is now to demonstrate by practical examples the application of these recommendations, and especially to illustrate the use of strut-and-tie models for designing discontinuity regions in concrete structures. These examples represent also a continuation of the 1990 FIP Handbook on Practical Design that had been based on the former (1984) version of the recommendations. Most of the examples are recently built existing structures. Although some of them may be considered as quite important, the chosen examples are by no means exceptional. The technical report does not deal with the discussion of aesthetic or general conceptual aspects. On the contrary, the main aim is to treat particular design aspects by selecting local regions of the chosen structures, that are then designed and detailed following the design principles and specifications proposed in the 1996 FIP Recommendations mentioned above. The document is believed to be of interest to all engaged in the design of structural concrete. It hopefully supports the use of more consistent design and detailing tools like strut-and-tie models.

Available in PDF, EPUB and Kindle. Book excerpt: A series of five detailed design examples feature the application of state-of-the-art strut-and-tie modeling (STM) design recommendations. This guidebook is intended to serve as a primary reference material for designers in the application of STM to bridge components. The examples are as follows: (Example 1) Five-Column Bent Cap of a Skewed Bridge: this design example serves as an introduction to the application of STM. Challenges are introduced by the bridge skew and complicated loading pattern. A clear procedure for defining nodal geometries is presented. (Example 2) Cantilever Bent Cap: a strut-and-tie model is developed to represent the flow of forces around a frame corner subjected to closing loads. This is accomplished, in part, through the design and detailing of a curved-bar node at the outside of the frame corner. (Example 3a) Inverted-T Straddle Bent Cap (Moment Frame): an inverted-T straddle bent cap is modeled as a component within a moment frame. Bottom-chord (ledge) loading of the inverted-T necessitates the use of local STMs to model the flow of forces through the bent cap cross section. (Example 3b) Inverted-T Straddle Bent Cap (Simply Supported): the inverted-T bent cap of Example 3a is designed as a simply supported member. Results for both the moment frame case and the simply supported case are compared to illustrate the influence of boundary condition assumptions. (Example 4) Drilled-Shaft Footing: three-dimensional STMs are developed to properly model the flow of forces through a deep drilled-shaft footing. Two unique load cases are considered to familiarize the designer with the development of such models.
Download or read book Strut and Tie Models written by Naveed Anwar and published by Butterworth-Heinemann. This book was released on 2017-09-01 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Strut and Tie Models: Analysis and Design presents a systematic and consistent approach to the application of the STM to almost all types of members using the arbitrary distinction between a D and a B region. Strut and tie modeling provides design engineers with a flexible and intuitive option for designing structures or portions that are heavily influenced by shear forces. The book also demonstrates how strut and tie modeling and finite element methods are not mutually exclusive but rather complementary and supportive. The book’s four part treatment starts with an overview of structural analysis and strut and tie models (STM). This is quickly followed by relevant topics such as: loads and load paths through members plus case studies, and formalization of strut and tie models. Applications of STM are then explained in detail along with extracting STM through FEM. In addition, the book will include solved examples and mobile apps. Includes moment curvature analysis, interaction diagrams and reinforcement design and stress analysis for structural cross sections Includes modeling tools and computational methods for cross-sections for stress distribution and stress calculations Features many illustrations, schematics, diagrams and line drawings Includes author-developed computer-based apps to be used in conjunction with the practical applications presented in the book Covers both the Eurocodes and American Concrete Institute codes, which are two major, widely-used building design code documents in the world according to researchgate.net
Download or read book Structural Design from First Principles written by Michael Byfield and published by CRC Press. This book was released on 2018-01-29 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: This enlightening textbook for undergraduates on civil engineering degree courses explains structural design from its mechanical principles, showing the speed and simplicity of effective design from first principles. This text presents good approximate solutions to complex design problems, such as "Wembley-Arch" type structures, the design of thin-walled structures, and long-span box girder bridges. Other more code-based textbooks concentrate on relatively simple member design, and avoid some of the most interesting design problems because code compliant solutions are complex. Yet these problems can be addressed by relatively manageable techniques. The methods outlined here enable quick, early stage, "ball-park" design solutions to be considered, and are also useful for checking finite element analysis solutions to complex problems. The conventions used in the book are in accordance with the Eurocodes, especially where they provide convenient solutions that can be easily understood by students. Many of the topics, such as composite beam design, are straight applications of Eurocodes, but with the underlying theory fully explained. The techniques are illustrated through a series of worked examples which develop in complexity, with the more advanced questions forming extended exam type questions. A comprehensive range of fully worked tutorial questions are provided at the end of each section for students to practice in preparation for closed book exams.
