This online lecture addresses challenges in correctly modelling the behaviour of materials acting together, the associated uncertainties, and required safety formats.

Non-linear Finite Element Modelling to simulate the behaviour of concrete structures under loading remains challenging. Advances in computing power are reducing run times and making the analysis technique more feasible for design and assessment. Significant challenges remain:
 
  • Modelling the behaviours of materials acting together correctly
  • Dealing with uncertainties in this behaviour
  • Setting requirements for safety formats.
Expert speakers will present case studies to illustrate successful modelling and modelling problems.

This event is organised by fibUK, the UK Group of the International Federation for Structural Concrete. 
 

Numerical simulation of reinforced concrete structures, safety formats and model uncertainty - Jan Cervenka, Cervenka Consulting

Non-linear analysis of reinforced concrete is based on the finite element method and constitutive laws for damage and failure of concrete, reinforcement and their interaction. Safety formats must include a suitable assessment of uncertainties in both the material properties and the true structural behaviour. A variety of examples will be presented, all of which have been analysed with software ATENA, to illustrate both the modelling and treatment of uncertainties.
 

Predicting performance of concrete structures using Non-linear Finite Element Analysis – Carl Brookes, Ramboll

Non-linear concrete modelling has mostly been used to assess existing structures to identify strength reserves and avoid costly strengthening. More recently, non-linear concrete simulations are being used for new construction. Carl’s presentation will provide examples ranging from tall buildings to strength assessment of concrete connections.
 

Eurocodes and non-linear methods: cautionary tales – Steve Denton, WSP

Eurocodes introduced the possibility of using non-linear analysis for design and provided high-level principles for modelling and establishing safety formats. The lack of full-codification leaves analysts with many decisions to make themselves, often heavily influenced by the recommendations within commercially-available software packages. Steve will cover examples where non-linear modelling has been challenging to recreate the true behaviour.
 

Speakers

Owen Brooker (Chair)

Technical Director, Modulus - Owen is a Chartered Civil and Structural Engineer and has a wide range of experience in the design of buildings using reinforced concrete, structural steelwork, timber, masonry and glass. Owen currently serves on a number of industry committees and is a marking examiner for the IStructE Chartered Membership exam.

Carl Brookes

Director, Ramboll - Carl leads Ramboll’s Engineering Simulation Team. He is an expert in performance-based design and assessment with considerable experience in construction analysis of bridges and tall buildings; non-linear simulation of concrete and masonry; special structural assessment and testing; analysis of historic structures; dynamic analysis of structures (vibration, earthquake, collision, blast); and structural monitoring.

Jan Cervenka

CEO, Cervenka Consulting s.r.o. (Prague) - Jan is the author and manager of ATENA software. He has research and practice experience in advanced material modelling and non-linear analysis of civil engineering structures, non-linear finite element method, fracture mechanics, plasticity and reliability assessment of new and existing structures.

Steve Denton

Executive Director and Head of Civil, Bridge and Ground Engineering, WSP - Steve heads WSP’s Technical Leadership Group. In addition to his business leadership responsibilities, Steve retains a high degree of involvement in technically demanding and complex projects. He is the Chair of CEN/TC 250, the international committee with overall responsibility for the Structural Eurocodes and is currently leading a major European effort to develop the second generation of these key design standards.
