This paper assesses the operational performance of drainage systems on four road bridges over the Sava River in Belgrade: Branko’s, Gazela, Ada Ciganlija, and Ostružnica. Field inspections identified deficiencies related to original design, subsequent modifications, ageing drainage infrastructure, structural and pavement deformations, and ina...

As many cable stayed bridges built in the 1960s reach the end of their original service life, replacing aging stay cable systems has become a major challenge for infrastructure owners. Corrosion, obsolete protection systems, and modern durability requirements drive the need to upgrade these structures with high performance cables. Freyssinet has de...

The reuse of precast reinforced concrete (RC) elements is an effective way to reduce the environmental impact of the construction industry. However, practical implementation remains limited by regulatory, technical, and market barriers. To facilitate reuse, the principles of design for deconstruction should be incorporated into precast structures. ...

This paper presents the main aspects of a comprehensive study of demountable steel-precast concrete connections consisting of a demountable bolt and embedded mechanical coupler with a rebar anchor. The study included experimental and numerical analysis of the connection under pure tension, pure shear, and combined shear and tension loading. The res...

This paper presents the development of an innovative steel-cross laminated timber (steel-CLT) shear connector designed for efficient shear transfer. The structural performance and mechanical behaviour of the proposed system were comprehensively evaluated through experimental testing and numerical modelling. Push-out tests were conducted to evaluate...

In recent years, 3D concrete printing (3DCP) technology has found growing application in residential construction, from single and two-storey houses to apartment buildings. Nevertheless, the wider application of this technology is limited by the lack of established standards and design codes, the development of which requires a sufficiently large e...
