Damage Analysis of Reinforced Concrete Structures due to High Temperatures

Fire or other events causing high temperature remain one of the serious potential risks to most buildings and structures. With the current state of knowledge, it is not possible to accurately predict the deformations due to high temperatures, which in many cases decide the structural failure mechanism. This was well documented by results of recent European research projects or studies by NIST. Spalling is another phenomena that can not be predicted or modelled. The objective of the proposed research project is to develop models and methods for coupled hygro-thermalmechanical analysis of reinforced concrete structures subjected to high temperatures. The developed methods and models should be applicable to practice and will reflect the current level of knowledge on this subject. The goal is to use a balanced approach, in which the same accuracy and modelling detail in all parts of the model (thermo-hygro-mechanical) will be represented. The research will be verified and evaluated by an experimental program.

I-SSB

The project aims to develop a new modular lightweight multi-level building concept based on multi-functional, load bearing dry-wall systems coupled with smart steel-stud/frame components.

Cervenka Consulting develops the FEM-program ATENA to carry out dynamic simulation of the load case earthquake for lightweight structures (generic term: 'Virtual Design Tool for Seismic Design of Lightweight Structures').

VITESPO 1ET409870411

VITESPO - Virtual testing of safety and reliability of structures Objective modelling of structural safety and reliability requires the application of advanced nonlinear methods based on fracture mechanics. Utilization of these methods in praxis is very difficult without an appropriate safety concept. The project objective is to develop numerical methods and algorithms for effective synthesis of nonlinear and probabilistic methods. Existing nonlinear solutions of the applicants will be extended for effective simulation of large scale problems utilizing iterative solvers, methods of multiscale modelling and Grid technologies. The method of stochastic finite elements within the framework of the finite elemement analysis models the probability of input parameters at two levels: random variables or random fields. Methods of stochastic simulation and neural networks will be also used for identification of material parameters.

UPTUN

The UPTUN project main objectives are: to develop innovative technologies where appropriate and where relevant comparing to and the assessment of existing technologies for tunnel application. Focus is on technologies in the areas of detection and monitoring, mitigating measures, influencing human response, and protection against structural damage.

To develop, demonstrate and promote procedures for rational safety level evaluation, including decision support models; and knowledge transfer.

Sustainable bridges

Sustainable bridges is a project which assesses the readiness of railway bridges to meet the demands of the 2020 scenario and provides the means for up-grading them if they fall short. The 2020 scenario requires increased capacities with heavier loads to be carried and bigger forces to be absorbed due to longer faster trains and mixed traffic. All type of bridges are being considered. You can read more about the project by pressing the project logo or project name above.
