Full scale analysis of the Crni Kal Viaduct
Published in Günther Meschke, René de Borst, Herbert Mang, Nenad Bićanić, Computational Modelling of Concrete Structures, 2020
The piers are made of concrete C 35/45 and reinforced with high ductile reinforcement S 500 and were constructed with the self-climbing formwork (SCF). The cross beams of piers 2–7 and Y-shaped arms are pre-stressed with tendons of 19–150 mm2. The central cell ofthe three-cell pier serves as installation chamber and manhole, with steel landings on maximal distance of 16m.
Numerical analysis of a foundation of a cooling tower in difficult geotechnical conditions
Published in António S. Cardoso, José L. Borges, Pedro A. Costa, António T. Gomes, José C. Marques, Castorina S. Vieira, Numerical Methods in Geotechnical Engineering IX, 2018
The execution of the ring foundation was the first stage of the construction. Precast concrete meridional columns (Fig. 1a) were installed afterwards, followed by the installation of precast lintel beams, increasing the stiffness of the lower part of the shell. Joints between structural elements were filled with cast-in-place concrete, thus enclosing the perimeter of the first ring of the shell. Then, it was used as the starting point for climbing formwork during casting of the shell (Fig. 1b). Following rings of the shell were cast-in-place (Fig. 1c), as so called “lifts”, in the number of 118, each 1,5 of height, with exception of last two at the top, designed as a part of cooling tower’s cornice.

Development of auto-climbing formwork system for composite core walls
Published in Journal of Asian Architecture and Building Engineering, 2022
The Auto-Climbing formwork System (ACS) is a method of construction in which the formwork is combined with a set of equipment such as hydraulic cylinders and guide profiles so that the system is supported by using anchor bolts on the lower story concrete wall, as shown in Figure 1, without being supported by a tower crane, and the system is automatically lifted along guide rails using a hydraulic jack. The ACS has been widely used around the world for bridge piers and high-rise reinforced concrete buildings. (Yang et al., 2012)
