This Guide describes and illustrates the various types of concrete slab-on-ground floor systems and suspended floors suitable for residential buildings ranging from single, detached houses to medium density buildings of apartments and flats. For slab-on-ground floors it provides an understanding of the footing/slab selection, design, detailing and construction requirements contained in AS 2870 and the Housing Provisions of the BCA. The requirements of AS 3660.14 are also covered. For suspended floors it covers both upper floors and those at ground level where a slab-on-ground may not be suitable. Forms of construction include insitu concrete (using either temporary or permanent formwork) and precast concrete (normal-weight and lightweight). It provides an understanding of the design approach, span-load charts to enable a selection of appropriate floor types, and design details and identifies various manufacturers/suppliers where appropriate. The Guide provides general information giving an appreciation of the relevant issues and Standards to be considered when planning and designing concrete floors. Alternative reinforced concrete floor systems and general site issues (eg slope, drainage) are discussed to assist in selecting the most practical footing/floor for a particular site. The information provides the basis for the selection by the designer; architect, engineer or building consultant of an appropriate floor system for a particular project. The Guide will in no way replace the services of professional consultants. For information on site supervision and recommended work practice for reinforced concrete floor construction readers are referred to The Housing Concrete Handbook 5.

The book introduces the theory of the structural loading on ships and offshore structures caused by wind, waves and currents, and goes on to describe the applications of this theory in terms of real structures. The main topics described are linear-wave induced motions, loads on floating structures, numerical methods for ascertaining wave induced motions and loads, viscous wave loads and damping, stationkeeping and water impact and entry. The applications of the theoretical principles are introduced with extensive use of exercises and examples. They include conventional ships, barges, high speed marine vehicles, semisubmersibles, tension leg platforms, moored or dynamic positioned ships, risers, buoys, fishing nets, jacket structures and gravity platforms. One aim of the book is to provide a physical understanding through simplified mathematical models. In this way one can develop analytical tools to evaluate results from test models, full scale trials or computer simulation, and learn which parameters represent the major contributions and influences on sea loads.

Recently I had a "struggle" with steel trapezoidal profiles - couldn't find any kind of web site offering geometrical data of the profiles along with its weight per square meter. Today I've found what I was looking for for long time, so I wanted to share this with you (maybe someone find this helpful as it was helpful to me), beside this all of you can add some other websites offering similar data to this thread.

Scrap Tire Derived Geomaterials - Opportunities and Challenges: Proceedings of the International Workshop IW-TDGM 2007 (Yokosuka, Japan, 23-24 March 2007)
Geomaterials derived from scrap tires continue to receive increased attention. These materials are now recognized as a suitable and alternative geomaterial, since they provide cost-effective solutions to many practical problems. This book presents current research and describes the latest advances in this promising field. It reflects the international significance of such recycled materials and discusses the use of whole tires, tire shreds, and tire chips, as well as tire chips mixed with soils and/or treated materials. Scrap Tire Derived Geomaterials also includes discussion about the geoenvironmental impact and assessment of these materials, with case studies, novel concepts, and field applications. It also contains information pertaining to mechanical properties and modeling.

In this report, two new approaches, both the state space approach and the Lagrangian approach, are developed to consider the structure as a dynamical system. These are mixed methods, wherein besides displacements, the stress-resultants and other variable of state are primary unknowns. These methods can potentially be used for the analysis of structures to collapse as demonstrated by numerical examples. Attention is focused on skeletal structures, although the extension of the methods to other systems is discussed. The methods suggested, can be coupled with suitable pre- and post-processors to develop a unified computational platform for analysis of collapsing structures. Several appendices are included along with numerous equations and diagrams.

This report investigates the failure mechanisms of shear-critical squat (ratio height to length of less than two) reinforced concrete walls, commonly used in many commercial buildings and nearly all safety-related nuclear structures. A database with experimental data obtained from 434 tests is assembled with the objective of improving the current state of knowledge on squat wall response. The adequateness of the peak shear strength prediction equations available in current design provisions is evaluated. Improved empirical equations are developed for peak shear strength prediction for rectangular walls and walls with boundary elements in a format suitable for inclusion in standards and codes of practice. Squat walls are modeled using finite elements to predict their monotonic and cyclic responses. Modeling decisions that are critical to predict the wall responses are explored and recommendations for finite element modeling are made. Macro-level hysteretic models are prepared for a small number of squat walls for which digital load-displacement data are available. The calibrated Ibarra-Krawinkler model is used to properly capture the strength, stiffness degradation, and pinching effects in the walls response. Information in the database is used to identify damage states and to develop fragility functions for buildings and safety-related nuclear structures incorporating squat reinforced concrete walls.
Manual for the seismic of steel and concrete buildings to Eurocode 8 is a document of IstructE.
It is useful to understand clear about eurecode 8 and detail of Reinforced concrete of steel element.
