Putting recycled concrete into practice in Belgium: From case studies over chain management to standards and quality assurance

Although there has been extensive research and several demonstration projects in Belgium and abroad, the use of recycled aggregates in concrete is still limited in practice. Several barriers were identified: lack of practical experience, limiting standards and the need for specific quality assurance. The paper describes recent developments in...

Influence of the group positioning of cylinders on the wind pressure distribution in the post-critical regime

In order to estimate the wind loads on circular cylindrical shell structures, the pressure coefficient as a function of the Reynolds number is given for an isolated cylinder in Eurocode 1 - Part 2-4: Actions on structures - Wind actions. As cylinders are often placed in groups and the configuration of these groups largely influences the pressure...
