Influence of Actual Curing Conditions on Mechanical Properties of Concrete in Bridge Superstructures
PublicationThis article presents the research on the mechanical characteristics of concrete in the construction of three concrete bridges. A system of recording the internal temperature of concrete and automatic control of laboratory ovens was used for specimen curing. This allowed the specimens to be cured under conditions similar to those occurring in the structure. Before the construction, reference blocks were used to define similar curing...

Raman Scattering versus Strain Engineering in Phosphorene Nanostructures: An Ab Initio Studies
PublicationThe one-dimensional nanoribbons made from phosphorene are novel structures with great applicability potential in material science. The significant carrier mobility combined with intrinsic semiconductor properties makes them ideal for application in electronics, and they are excellent candidates for sensing material. The lack of a well–established multiscale modelling strategy for phosphorene nano optoelectronic devices is one of...

Strain gauges monitoring of arch bridge over the Vistula river in Toruń during construction
PublicationIn 2013 one of the biggest Polish road bridges over the Vistula was built in Torun. Considering the use of original engineering solutions and innovative assembly it was decided on monitoring of strain gauges and assessment of building’s behaviour during its construction. The research was aimed at determining the degree of strain and the assessment of proper work of main arch girders during assembly phases. This work presents the...

Experimental and numerical study on stability loss of innovative geometry steel girder
PublicationThis paper presents the experimental and numerical analysis of an innovative plate girder geometry with variable web thicknesses. An idea proposed in this research is to increase the stability of the girder web by increasing its thickness in the compressed zone. This solution can replace commonly used longitudinal stiffeners which are designed to prevent web local loss of stability. Moreover, such an innovative approach requires...
