This textbook is for courses on Mechanical Behavior of Materials taught in departments of Mechanical Engineering and Materials Science. The text includes numerous examples and problems for student practice. The book emphasizes quantitative problem solving. End of the chapter notes are included to increase students' interest. This text differs from others because the treatment of plasticity has greater emphasis on the interrelationship of the flow, effective strain and effective stress and their use in conjunction with yield criteria to solve problems.
The treatment of defects is new. Schmids law is generalized for complex stress states. Its use with strains allows for prediction of R-values for textures. Another feature is the treatment of lattice rotations and how they lead to deformation textures. The chapter on fracture mechanics includes coverage of Gurney's approach. Much of the analysis of particulate composites is new. Few texts include anything on metal forming.

This report contains the findings of a study to determine load factors for use in evaluating the load capacity of existing bridges. The report includes recommended values for load factors and presents the methodology and data used to calibrate the factors to provide appropriate safety margins. The material in this report will be of immediate interest to bridge engineers involved in bridge load rating and to engineers interested in the development of load and resistance factor rating procedures.

Structures cannot be created without engineering theory, and design rules have existed from the earliest times for building Greek temples, Roman aqueducts and Gothic cathedrals -- and later, for steel skyscrapers and the frames for aircraft. This book is, however, not concerned with the description of historical feats, but with the way the structural engineer sets about his business. Galileo, in the seventeenth century, was the first to introduce recognizably modem science into the calculation of structures; he determined the breaking strength of beams. In the eighteenth century engineers moved away from this 'ultimate load' approach, and early in the nineteenth century a formal philosophy of design had been established -- a structure should remain elastic, with a safety factor on stress built into the analysis. This philosophy held sway for over a century, until the first tests on real structures showed that the stresses confidently calculated by designers could not actually be measured in practice. Structural engineering has taken a completely different path since the middle of the twentieth century; plastic analysis reverts to Galileo's objective of the calculation of ultimate strength, and powerful new theorems now underpin the activities of the structural engineer.This book deals with a technical subject, but the presentation is completely non-mathematical. It makes available to the engineer, the architect and the general reader the principles of structural design.

This manual extends the Instructions reported on page 4 of the form, with the aim of providing a tool for a correct training of the surveyors and for a full awareness of the principles of the form, as well as for the necessary homogeneity of judgment.
In Chapter 2, some information and guidelines on issues concerning the organisation of the damage and usability survey and the procedures for preparing and carrying out the building survey are given.
Chapter 3 provides a detailed description of each structural component, correlating it to the building component behaviour (thrusting or non thrusting roofs, masonry of good or bad quality, rigid or flexible floors, etc.). The layout of the data collection (i.e. of the form) relay on the personal opinion of the surveyor about the quality of the constructive components in the specific case under study. It is in fact possible that the manual does not consider a particular typology or that a given typology in a given area or in a specific building exhibits a seismic behaviour different from what can normally be expected, being it due to the maintenance state, or to the particular characteristics of a material used in that single case. For the general considerations expressed in the previous sections, the guidelines of section 4, concerning the damage survey of the main structural components (Chapter 4), are very wide and exhaustive.
Chapters 3 and 4 have many pictures and figures attached, respectively in the abacus of the construction typologies and in the examples of seismic damage. They offer an important reference inventory for the surveyor, that can help him in understanding the relationships between the observed reality and the descriptive synthesis operated when compiling the form. It is evident that a correct use of the form requires a complete understanding of the expected seismic behaviour of different structural components. This way, he can develop an independent ability in associating the typology to the behaviour, ability that he should use any time the encountered typology is not described in detail in the manual. An unquestionable advantage of this approach lies also in its didactic potentiality towards the inspectors. The need of giving in any case an opinion about each constructive component induces a global opinion about the building vulnerability which, associated to the damage assessment, produces a mature usability assessment (Chapter 5).

Serves as a supplemental text for an undergraduate and a primary textbook for a graduate course, and as a reference for practicing engineers and researchers in computational mechanics. Dow (structural mechanics, U. of Colorado-Boulder) provides background material about finite element results and techniques that can improve their accuracy. From a common theoretical foundation, he develops three error analysis techniques: modeling errors in individual elements, discretization errors in the overall model, and point-wise errors in the final stress or strain results.

Abstract:
In earthquake resistant design of RC frame buildings, capacity design of columns in flexure
is appIied to eliminate the possibiIity of storey sway mechanisms and to spread the
inelastic deformation demands and energy dissipation throughout the structure. The
paper considers two alternative column capacity designs: the conventional, full capacity
design of columns relative to the beams, and the relaxed one allowed by Eurocode 8 depending
on how much the seismic action controIs the flexural capacity of beams. Twelve
RC frame buildings, designed in detail according to the two capacity design alternatives,
are nonlinearly analysed under spectrum-compatible motions applied separately in the
two horizontal directions and scaled to intensity from once to twice the design ground
motion. In both design versions the slab participation to the beam tension flange is
considered either as in the design calculations - including those of capacity design -
i.e. very little, or as expected in reality, i.e. very significant. In most cases the dynamic
response to the design-level motion is found to be nearly elastic, due to the overstrength
of materials and members and to the "understress" of the structure due to crackinginduced
softening. At higher motion intensities the effect of column capacity design and
of the slab participation to the beam flexural capacity is not dramatic: column inelasticity
and some light damage cannot be prevented by relaxed or full capacity design, while
the large participation of the slab to the beam negative moment capacity does not overly
distort the strength balance between beams and columns or the seismic response of the
structure. Under any circumstances, column plastic hinging does not lead to a storey
sway mechanism.
