Knowing the safety factor for limit states such as plastic collapse, low cycle fatigue or ratcheting is always a major design consideration for civil and mechanical engineering structures that are subjected to loads.
Direct methods of limit or shakedown analysis that proceed to directly find the limit states offer a better alternative than exact time-stepping calculations as, on one hand, an exact loading history is scarcely known, and on the other they are much less time-consuming.
This book presents the state of the art on various topics concerning these methods, such as theoretical advances in limit and shakedown analysis, the development of relevant algorithms and computational procedures, sophisticated modeling of inelastic material behavior like hardening, non-associated flow rules, material damage and fatigue, contact and friction, homogenization and composites.

Full-Scale Testing and Foundation Design (Geotechnical Special Publication - GSP 227)
Author: Mohamad H. Hussein, K. Rainer Massarsch, Garland E. Likins, Robert D. Holtz | Size: 47 MB | Format:PDF | Quality:Unspecified | Publisher: ASCE | Year: 2012 | ISBN: 0784412081
Full-Scale Testing and Foundation Design, GSP 227, honors Bengt H. Fellenius, Dr.Tech., P.Eng., for his noteworthy efforts to advance foundation engineering research, design, construction, and testing practices. From the beginning in Sweden of his 50-year career as a geotechnical engineer through nearly two decades as a professor of civil engineering at the University of Ottawa, Dr. Fellenius has made outstanding contributions in the international arena to the development and advancement of innovative approaches and practical methods for incorporating full-scale testing in foundation design, especially for deep foundations. This collection contains 51 papers on the use of full-scale testing to enhance the design of foundations. Eighteen papers are reprints of landmark articles authored or co-authored by Dr. Fellenius. Thirty-three additional peer-reviewed papers written especially for this collection present test methods for various types of foundations and describe useful applications in a diversity of situations. These papers offer findings from interesting projects and document valuable lessons learned by some of the leading experts in the field of foundation engineering from around the world. Full-Scale Testing and Foundation Design contains technical and practical information that will be valuable to geotechnical engineers, foundation specialists, researchers, and construction engineers.

Although finite element courses have become more popular in the undergraduate and graduate engineering, science, and applied mathematics curricula, there are very few introductory textbooks geared toward students accustomed to using computers for everyday assignments and research. 'An Introduction to Linear and Nonlinear Finite Element Analysis' fills this gap, offering a concise, integrated presentation of methods, applications, computational software tools, and hands-on programming projects. Suitable for junior/senior undergraduate and first-year graduate courses, the book is aimed at students from a variety of disciplines: engineering, physics, geophysics, and applied mathematics.
Unlike existing texts designed with specific applications to a particular field of mechanical, civil, or chemical engineering, the emphasis here is on interdisciplinary applications. One- and two-dimensional linear and nonlinear initial/boundary value problems are solved using finite element, Newton's, and conjugate gradient methods. Mathematical theory is kept to a minimum, making the text accessible to students with varied backgrounds.

I have worked as a structural engineer in the industrial sector since graduating (steel structures, concrete footings / slabs etc). I would like to start expanding my skill base so I can look at providing engineering services to the residential sector (in Australia).
I would like to hear from other members who service the residential sector (mainly new housing construction) to see what typical work consists of (note I am looking at rural areas, so pretty basic construction). What references is available familiarize myself with the process of designing timber / masonry structures to current best practices (Australian Standards give design requirements, however there are usually good rules of thumb to follow which are not included in such documents)? What type of work do engineers in this sector typically target? Verification? Certification? Where do engineers go to get experience working with new products such as those available for retaining wall construction etc.?
I would appreciate a constructive discussion on the points above. I am a competent engineer in my area of practice, however I need to know how feasible it is to break into the residential market since the location I am thinking of targeting has relatively few structural engineers in the region and hence I wont have a large support network available. Ideally I would work for a residential engineering company for first but that isn't really an option at the moment (no one is hiring + it's not very professional to work somewhere for 6 months soak up all their IP then take off and work for yourself).
This book presents recent advances related to the following two topics:
- how mechanical fields close to material or geometrical singularities such as cracks can be determined;
- how failure criteria can be established according to the singularity degrees related to these discontinuities.
Concerning the determination of mechanical fields close to a crack tip, the first part of the book presents most of the traditional methods in order to classify them into two major categories. The first is based on the stress field, such as the Airy function, and the second resolves the problem from functions related to displacement fields. Following this, a new method based on the Hamiltonian system is presented in great detail. Local and energetic approaches to fracture are used in order to determine the fracture parameters such as stress intensity factor and energy release rate.
The second part of the book describes methodologies to establish the critical fracture loads and the crack growth criteria. Singular fields for homogeneous and non-homogeneous problems near crack tips,
v-notches, interfaces, etc. associated with the crack initiation and propagation laws in elastic and elastic-plastic media, allow us to determine the basis of failure criteria.
Each phenomenon studied is dealt with according to its conceptual and theoretical modeling, to its use in the criteria of fracture resistance; and finally to its implementation in terms of feasibility and numerical application.

The Complete Guide to Preventing Architectural Water Infiltration Issues
This insightful guide illustrates how to fortify buildings to withstand the onslaught of nature, primarily against wind and rain, with a back-to-basics look at water infiltration prevention techniques. This guide for architects and builders:
Includes an overview of general guidelines as well as coverage of applications such as those used in below-grade conditions, sealants, and membranes
Covers massing, orientation, seismic issues, wind loads, and discussion of building systems
Examines the key factors causing water infiltration in buildings: exposure, thermal loads, structural movement, and building configuration
With solid advice from experts in the field, The Architect's Guide to Preventing Water Infiltration shows how innovations in today's construction techniques simply won't hold water if they don't follow the fundamental ground rules necessary to keep water out.

Significantly updated with revisions to nearly all 200-plus details, this second edition of Architect's Handbook of Construction Detailing provides architects, engineers, interior designers, contractors, and other building professionals with all of the common construction details, materials information, and detailing concepts used throughout the industry.
The information can be used as is or modified to fit individual project designs. Each of book's seven sections -- formatted to follow the new six-digit CSI MasterFormat system -- contains details and related information, including descriptions, detailing considerations, material requirements, installation requirements, tolerance coordination, and likely failure points. Additionally, SI (metric) equivalents have been added to all dimensions

I would be grateful if someone could share the old version of the Snow loads part of Eurocode (EN 1991-1-3. Actions on structures. General actions. Snow loads).
I am looking for a version published before 2003. Thank you in advance.
