Design Of Concrete Structures

Designed for courses in the design of concrete structures or reinforced concrete design, this text aims to help readers gain a firm understanding of the behaviour of reinforced concrete and a proficiency in the methods used in current design practice.

The 13th edition of the classic text," Design of Concrete Structures," is completely revised using the newly released 2002 ACI Code. The text covers the behavior and design aspects of concrete and provides thoroughly updated examples and homework problems throughout. The 13th edition features a new chapter, Chapter 10, covering strut-and-tie models, although the two-pronged objectives of (1) establishing a firm understanding of the behavior of reinforced concrete, and (2) developing proficiency in the methods used in current design practice are retained. The text presents the basic mechanics of structural concrete and methods for the design of individual members for bending, shear, torsion, and axial force, and also provides detail in the various types of structural systems applications.

The 14th edition of the classic text, Design of Concrete Structures, is completely revised using the newly released 2008 ACI (American Concrete Institute) Code. This new edition has the same dual objectives as the previous editions; first to establish a firm understanding of the behavior of structural concrete, then to develop proficiency in the methods used in current design practice. Design of Concrete Structures covers the behavior and design aspects of concrete and provides updated examples and homework problems. New material on slender columns, seismic design, anchorage using headed deformed bars, and reinforcing slabs for shear using headed studs has been added. The notation has been thouroughly updated to match changes in the ACI Code. The text also presents the basic mechanics of structural concrete and methods for the design of individual members for bending, shear, torsion, and axial force, and provides detail in the various types of structural systems applications, including an extensive presentation of slabs, footings, foundations, and retaining walls.

17 2 STRESS FIELDS FOR SIMPLE STRUCTURES 2. 1 INTRODUCTION In this chapter the behavior and strength of simple structures made of rein forced or prestressed concrete is investigated with the aid of stress fields. In particular, the webs and flanges of beams, simple walls, brackets, bracing beams and joints of frames are investigated. By this means, the majority of design cases are already covered. In reality, all structural components are three-dimensional. Here, however, components are considered either directly as two-dimensional plate elements (i. e. the plane stress condition with no variation of stress over the thickness of the element) or they are subdivided into several plates. Since two-dimensional structural elements are statically redundant, it is pOSSible for a particular loading to be in equilibrium with many (theoretically an infinite number of) stress states. If the lower bound method of the theory of plasticity is employed, then an admissible stress field or any combination of such stress fields may be selected. In chapter 4 it is shown that this method is suitable for the design of reinforced concrete structures, and the consequence of the choice of the final structural system on the structural behavior is dealt with in detail. The first cases of the use of this method date back to Ritter [6] and Morsch [4], who already at the beginning of the century investigated the resultants of the internal stresses by means of truss models.

This introduction to the principles of concrete mechanics and design focuses on the fundamentals - from very basic, elementary to the very complicated concepts and features an easy-to-follow yet thorough step-by-step design methodology. *emphasizes basic principles of the mechanics aspects of concrete design and avoids explanations of the detail requirements which can be found in the ACI Code and Commentary. *surveys modern design philosophies and features an amply illustrated tour of the world of concrete. *carefully lays out the various design procedures step-by-step - for flexural design, shear design, column design, etc, prepares and encourages students to program procedures for computer solution. Instructors, at their own discretion, can suggest follow-up coding assignment. *goes beyond the traditional description of materials to provide substantive coverage of concrete, current concrete technology, and the durability of materials - especially since many engineers will find themselves repairing, rehabilitating, and strengthening existing structures, rather than designing new ones. *explores the interrelationship between design and analysis - a typical problem area for students, especially in relation to statically indeterminate structures, reviews some structural analysis methods for continuous beams and frames, especially those methods that designers will find useful for checking purposes - e.g., moment distribution, explains how the behavior of structures can be controlled through design decisions. *includes sections on basic plate theory and yield line theory as supplements to the common design procedures of the ACI Code. *contains important optional topics that students can master through self-study after understanding the basics such as torsion, slab design, footings, and retaining walls. *includes many easy-to-follow examples worked out in great detail. *contains a large number of illustrations. *features very carefully designed problem sets that require students to think and appreciate various physical aspects of what they are doing. *contains a comprehensive glossary of terms common in concrete engineering and the construction industry. Definitions are based largely on The Cement and Concrete Terminology Report of ACI Committee 116.

By designing in corrosion prevention and through preventive maintenance, the overall service cost of a concrete structure can be substantially reduced. This book takes a probabilistic approach to the engineering design issues for controlling durability and service life of concrete structures in severe environments. Many durability problems are caused by poor quality control as well as special problems during concrete construction. The issue of construction quality and variability need to be grasped before durability can be successfully controlled. This book helps by giving: reviews of field performance, deteriorating processes and current codes and practice methods for calculation of corrosion probability; performance-based concrete quality control; corrosion prevention and preventive maintenance calculation of life cycle costs and life cycle assessment recommended job specifications. Internationally relevant with a practical focus, this is the essential guide for consulting and construction engineers involved in the design and execution of new concrete structures.
