Gaussian models for bond strength evaluation of ribbed steel bars in concrete

A precise prediction of the ultimate bond strength between rebar and surrounding concrete plays a major role in structural design, as it effects the load-carrying capacity and serviceability of a member significantly. In the present study, Gaussian models are employed for modelling bond strength of ribbed steel bars embedded in concrete....

Methodology and Tools for Testing, Numerical Analysis and Design of the 3D Printed Moulds

The large-scale 3D printing technology created by a group of partners led by DUS Architects allows fabricating components made of thermoplastic polymers with Fused Deposition Modelling technique. These components can be used as moulds for concrete elements, providing freedom of form and unprecedented optimization opportunities. In this report...

Modelling the influence of cracking and healing on modal properties of concrete beams

Concrete structures are commonly cracked when in service. To overcome issues arising from cracking, self-healing concrete is being developed. Together with the development of the material, techniques to verify and quantify self-healing are being developed. A number of destructive techniques have been used in the past. It would be beneficial to...
