Bridge Design to Eurocodes: UK Implementation
Description
As of April 2010, Eurocodes replaced British Standards as the principal design standards for bridges in the UK. In support of the transition the Bridge Design to Eurocodes: UK Implementation conference held at the Institution of Civil Engineers in November 2010 brought important background and explanatory information into the public domain. The proceedings of this conference provide an enduring record of the UK’s Eurocodes implementation for bridge design, with papers written by invited experts who have been at the very heart of Eurocode developments in the UK. Readers are provided with the key technical decisions taken in the development of the National Annexes, as well as important sources of complementary information and practical advice on applying the codes.
Providing definitive, essential and practical information on the implementation of the Eurocodes for bridge design in the UK, this book is essential reading for bridge owners, managers, designers, consultants, contractors, local or central government engineers, academics, and software developers, that is anyone interested or involved in the design, build, maintenance or ownership of bridges.
Analysis and modelling of the seismic behaviour of high ductility steel-concrete composite structures
Author: Ph.D student: Eng. Fabio Ferrario | Size: 20.3 MB | Format:PDF | Quality:Unspecified | Publisher: Dipartimento di Ingegneria Meccanica e Strutturale Facoltà di Ingegneria | Year: 2004 | pages: 263
In this thesis theoretical, experimental and numerical aspects and applications concerning the seismic behaviour of high ductility steel-concrete composite structure are analysed. The interest has been focused on the capability of framed structures to dissipate seismic energy by means of inelastic deformations. The basic design parameter in this approach is the ductility that should be considered as a conceptual framework in the Performance-Base Seismic Engineering (PBSE). PBSE has been developed encompassing the full range of seismic engineering issues to be referred to design of structures for predictable and controlled seismic performance within establishedlevels of risk.The attention has been focalised on different solutions of steel and steel-concrete composite beam-to-column joints assuring the necessary ductility that can be obtained not only through careful study of building morphology, structural schemes and construction details, but also through the rational use of materials. Three specific and related topics have been analyzed and detailed analyses and experimental tests on substructures have been performed in order to ensure large inelastic deformations and the necessary energy dissipation under earthquake strong motion. The results aiming at qualifying the dissipative and rotational capacities of a particular typology of beam-to-column joints are then illustrated and discussed. The objective of this study is to provide designers with precise rules regarding constructional solutions suitable to each scheme and to the associated design methodologies necessary for evaluating their performances.

Nonlinear Static Analysis to Assess Seismic Performance and Vulnerability of Code - Conforming RC Buildings
Author: A. CINITHA.A , P.K. UMESHA , NAGESH R. IYER | Size: 1.4 MB | Format:PDF | Quality:Unspecified | Publisher: WSEAS TRANSACTIONS on APPLIED and THEORETICAL MECHANICS | Year: 2012 | pages: 10
The seismic zone map of Indian subcontinent emphasis that more than 60% of land is under severe
to moderate earthquake and approximate hábitat requirement is 2025 lakhes of buildings in each year. The
adequacy of post occupancy of buildings after an earthquake is highly demanded. This paper investigates
seismic performance and vulnerability analysis of 4storey and 6storey codeconforming (IS: 4562000, Indian
standard for plain and reinforced concrete code and IS: 18932002, Indian standard criteria for earthquake re
sistant design of structures) reinforced concrete (RC) buildings. The buildings are designed for two different
cases such as ordinary moment resisting frame (OMRF) and special moment resisting frame (SMRF). The non
linear static analysis (pushover analysis) is used to capture initial yielding and gradual progressive plastic be
haviour of elements and overall building response under seismic excitations. The deformation characteristics of
structural elements are essential to simulate the plastic hinge formation in the process of generation of capacity
curve during the pushover analysis. An analytical procedure is developed to evaluate the yield, plastic and ulti
mate rotation capacities of beams and columns along with different plastic hinge lengths. In the present study,
user defined plastic hinge properties of beams and columns are modeled using analytical expressions developed
based on Eurocode 8 and incorporated the same in pushover analysis using SAP2000. The nonlinear static
analysis is carried out for load patterns proportional to fundamental mode. The analysis gives an estimate of
seismic capacity of the structural system and its components based on its material characteristics and detailing
of member dimensions. A 100% dead load plus 50% live load is applied prior to the lateral load in the push
over analysis. The building performances are assessed with the capacity curve generated. Performance levels
are used to describe the limiting damage condition, which may be considered satisfactory for a building under
specific earthquake. The performance levels are expressed in terms of target displacement, defined by limiting
values of roof drift, as well as deformation of structural elements. The three performance levels considered in
the present study are immediate occupancy, life safety and collapse prevention. The vulnerability of the build
ings is estimated in terms of vulnerability index to assess the performance of the building.

CHAVEZ GARCIA , Kyriazis PITILAKIS | Size: 0.74 MB | Format:PDF | Quality:Unspecified | Publisher: 4th International Conference on Earthquake Geotechnical Engineering June 25-28, 2007 Paper No. 1659 | Year: 2007 | pages: 17
This paper presents a numerical study of the seismic response of ancient columns. The multidrum
column analysed here corresponds to the Hellenistic portico of Lindos acropolis. This
structure was modelled using a finite element model, which also included its base. The
simulations were made in three dimensions. Extensive time domain parametric analyses were
performed in order to examine the behaviour of the column subjected to seismic motion
having different values of peak ground acceleration. The seismic input used consisted of
horizontal components of three earthquakes, with different frequency content. Three different
systems connecting the drums of the column are analysed in order to examine their influence
on the seismic response of the column. Our study takes into account the complex behaviour of
the structure with the aim to determine the PGA value that is the threshold before its collapse.
Finally, we present a procedure to estimate the dominant period of a monolithic, a multidrum,
and two multidrum columns connected with an architrave from microtremors
measurements. The results of the microtremor measurements are compared with the
numerical simulations to assess the effectiveness of the procedure. Our results show that
microtremor measurements are useful to estimate the modal shapes of ancient columns.

Nonlinear Seismic Response Analysis of Realistic Gravity Dam-Reservoir Systems
Author: P.G. Asteris, A.D. Tzamtzis | Size: 0.4 MB | Format:PDF | Quality:Unspecified | Publisher: International Journal of Nonlinear Sciences and Numerical Simulation 4(2003) 329-338 | Year: 2003 | pages: 10 | ISBN: Freund Publishing House Ltd
A methodology for the earthquake response analysis of concrete gravity dam-reservoir systems is
presented, giving emphasis at the development of an appropriate nonlinear model capable of reproducing the
effects on response of all the forms of nonlinearities present in a realistic system. The numerical simulation of
the displacement response history of a real-life system to a known seismic excitation has been performed
using the finite element method and specially developed interface elements have been employed to model the
discontinuities of the structure. The results obtained demonstrate that the earthquake response of the system is
significantly affected by the behaviour at the interfaces between contacting materials.
