In 1989, the Steel Construction Institute produced publication P076[1] entitled ‘Design Guide on the Vibration of Floors’. From vibration measurements taken over the last 10 years on steel-framed floors, it was decided that a new version of the publication was required: to extend the guidance to new forms of construction (such as Slimdek®); to include guidance on special floors (such as dance floors); and, from calibrating numerical models against test performance, to develop a new design methodology.
Following the publication of P354[2] entitled ‘Design of Floors for Vibration: A New Approach’, P076 and P331[3] have been withdrawn. This article reviews the new publication, indicating and explaining changes.

Mechanics and model-based control are both rapidly expanding scientific fields and fundamental disciplines of mechatronics, sharing demanding mathematical and system-theoretic formulations and methods. The papers in this volume deal with smart materials, which allow the design and implementation of new types of actuator/sensor fields and networks. Main topics treated are fundamental studies on laminated, composite and functionally graded materials, thermal and piezoelectric actuation, active and passive damping, as well as vibrations and waves in smart structures. The book is based on the 1st Japanese-Austrian Workshop which took place in Linz in Fall 2008.

This guide was prepared for two reasons. Firstly, the introduction of BS 5950-1:2000 highlighted the need to check the sway stability of all frames, including braced frames. Whilst this was required in the 1990 version of the Standard, common practice was to ignore the check for braced frames. Frame stability checks are therefore relatively new in practice, and deserve explanation. Secondly, no complete guide existed for what is a very important form of construction in the UK – multi-storey steel-framed buildings.
Whilst the design of elements within a frame, such as beams and columns, is covered elsewhere, and is not of itself particularly challenging, a guide covering the wider aspects
of multi-storey design was considered to be a valuable addition.
This guide does not attempt to repeat exhaustive coverage on the design of elements if these are covered elsewhere, but directs the reader to the resources that already exist.
Instead, the guide offers advice on layout, floor systems and typical element sizes, so that the scheme design can be carried out with confidence.

When dealing with rock in civil engineering, mining engineering and other engineering, the process by which the rock fails under load should be understood, so that safe structures can be built on and in the rock. However, there are many ways for loading rock and rock can have a variety of idiosyncracies. This reference book provides engineers and researchers with the essential knowledge for a clear understanding of the process of rock failure under different conditions. It contains an introductory chapter explaining the role of rock failure in engineering projects plus a summary of the theories governing rock failure and an explanation of the computer simulation method. It subsquently deals in detail with explaining, simulating and illustrating rock failure in laboratory and field. The concluding chapter discusses coupled modelling and the anticipated future directions for this type of computer simulation. An appendix describing the RFPA numerical model (Rock Failure Process Analysis program) is also included.

The monography offers a detailed analysis of the methods for constructing mathematical models of transient non-isothermal flows of gas mixtures, multicomponent fluids, and gas–liquid fluids through systems of long branched pipelines including annular sections. To enhance the presentation clarity, the proposed methods are extended to the modeling of flows of heat-conducting multicomponent
liquids through long branched open channels.
Together with the model construction methods, the strategies of their numerical analysis are discussed in detail, with the use of various classes of finite-difference schemes, including completely conservative spline schemes of high approximation order. Special emphasis is placed on expounding the method of Lagrangian particles as applied to the analysis of heat-conducting multicomponent liquids transmitted through open channels and to the study of complex flows in linear and annular pipeline networks.
The methods for constructing mathematical models for functioning of trunklines and gas distribution systems operated in gas industry are also discussed in detail. They involve the strategies for prognostic optimization of costs covering the full range of natural gas transmission modes, failurepreventing algorithms (e. g., in case of pipeline ruptures or surge in compressor house networks), and new methods for identifying sources of unrecovery and automated tuning of model parameters to the characteristics of actual pipeline networks. All the described methods for constructing mathematical models and their analysis have been developed within a unique modeling framework, which considerably simplifies their study and practical application. During the last decade, the reliability and efficiency of these methods have been confirmed
in practice, in solving industrial problems.
The monography can be useful to researchers, postgraduate students, and educators dealing with mathematical modeling, software application development, and working on computational and analytic problems for the needs of pipeline transmission, engineering industries, power industry, and environmental organizations. The presentation is accessible to undergraduate students of engineering.

The book summarizes the well established as well as the newest constitutive formulations that describe the variety of possible loadings beginning with quasi-static to impact. The rate dependence is crucial in the description. The implementation of discussed phenomenological physical laws into the environment of numerical codes is in focus of presentation. Numerical examples prove the importance of using the new constitutive properties in design.

This book comprehensively treats the formulation and finite element approximation of contact and impact problems in nonlinear mechanics. Intended for students, researchers and practitioners interested in numerical solid and structural analysis, as well as for engineers and scientists dealing with technologies in which tribological response must be characterized, the book includes an introductory but detailed overview of nonlinear finite element formulations before dealing with contact and impact specifically. Topics encompassed include the continuum mechanics, mathematical structure, variational framework, and finite element implementations associated with contact/impact interaction. Additionally, important and currently emerging research topics in computational contact mechanics are introduced, encompassing such topics as tribological complexity, conservative treatment of inelastic impact interaction, and novel spatial discretization strategies.
