Hybrid Simulation: Theory, Implementation and Applications
Author: Victor Saouma, M.V. Sivaselvan | Size: 8.05 MB | Format:PDF | Publisher: Taylor & Francis | Year: 2008 | pages: 242
Hybrid Simulation deals with a rapidly evolving technology combining computer simulation (typically finite element) and physical laboratory testing of two complementary substructures. It is a cost effective alternative to shaking table test, and allows for the improved understanding of complex coupled systems. Traditionally, numerical simulation and physical tests have been uncoupled and performed separately. In this simulation paradigm the coupled nature of the simulation allows for improved understanding, and more efficient design since the factor of safety does not have to be arbitrarily inflated to account for uncertainties of uncoupling. It is a multidisciplinary technology which relies heavily on control theory, computer science, and numerical techniques.

This Second Edition of a standard numerical analysis text retains organization of the original edition, but all sections have been revised, some extensively, and bibliographies have been updated. New topics covered include optimization, trigonometric interpolation and the fast Fourier transform, numerical differentiation, the method of lines, boundary value problems, the conjugate gradient method, and the least squares solutions of systems of linear equations. Contains many problems, some with solutions.

This British Standard, a part of the BS 7036 series, provides guidance to manufacturers, suppliers, installers, specifiers, occupiers and property owners on the general recommendations for the provision, installation, safe operation and maintenance of powered door systems with a view to safeguarding traffic against the risk of accidents.
Although this code of practice is not intended to include industrial type powered doors and powered turnstiles, gates and barriers, the guidance given may be helpful for such installations.
This British Standard is not intended to cover the manufacture or design of powered door operating systems except where the products, components or devices have a bearing on the question of safety, nor does it cover the application of powered doors to specific installations.

BS EN 115-1 defines safety requirements for escalators and moving walks in order to safeguard people and objects against risks of accidents during installation, operation, maintenance and inspection work.
BS EN 115-1 applies to new escalators and moving walks (pallet or belt type.
BS EN 115-1 deals with all significant hazards, hazardous situations and events relevant to escalators and moving walks when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer.
BS EN 115-1 does not deal with hazards arising from seismic activities.
BS EN 115-1 is not applicable to escalators and moving walks which were manufactured before the date of its publication as EN. It is, however, recommended that existing installations be adapted to this standard.

This book discusses free vibration of single-degree-of-freedom (SDOF) systems and forced vibration of SDOF systems. It covers response to periodic dynamic loadings and impulse loads and two degrees of freedom linear system response methods and free vibration of multiple degrees of freedom. Topics include time history response by natural mode superposition, numerical solution methods for natural frequencies and mode shapes and differential quadrature, transformation, and Finite Element methods for vibration problems. The book also touches on earthquake ground motion, response spectra, and earthquake analysis of linear systems are discussed. Worked examples in Mathematica and Matlab are given.

The repair of deteriorated, damaged and substandard civil infrastructures has become one of the most important issues for the civil engineer worldwide. This book discusses the use of externally bonded fibre-reinforced polymer (FRP) composites to strengthen, rehabilitate and retrofit civil engineering structures, covering such aspects as material behavior, structural design and quality assurance.
The first three chapters of the book review structurally deficient civil engineering infrastructure, including concrete, metallic, masonry, and timber structures. FRP composites used in rehabilitation and surface preparation of the component materials are also reviewed. The next four chapters deal with the design of FRP systems for the flexural and shear strengthening of reinforced concrete (RC) beams and the strengthening of RC columns. The following two chapters examine the strengthening of metallic and masonry structures with FRP composites. The last four chapters of the book are devoted to practical considerations in the flexural strengthening of beams with unstressed and prestressed FRP plates, durability of externally bonded FRP composite systems, quality assurance and control, maintenance, repair, and case studies.
With its distinguished editors and international team of contributors, Strengthening and rehabilitation of civil infrastructures using fibre-reinforced polymer (FRP) composites will be a valuable reference guide for engineers, scientists and technical personnel in civil and structural engineering working on the rehabilitation and strengthening of the civil infrastructure.
