Damage of prestressed concrete railway sleepers and its impact on durability
(International Conference Modern Building Materials, Structures and Techniques (MBMST 2019), 2019)Prestressed concrete railway sleepers are the most widespread sleepers due to their stiffness and high bearing capacity. They transfer train induced loads from the rails directly to the ballast and therefore are the most ... -
Experimental investigation on friction between foundation slabs and substructure
(International Conference Modern Building Materials, Structures and Techniques (MBMST 2019), 2019)For verification of structural safety (ultimate limit states – ULS) and serviceability (serviceability limit states – SLS) of reinforced concrete structures direct and indirect actions must be considered. The main reason ... -
Advanced computational methods of perpendicularly loaded laminated glass panes
(International Conference Modern Building Materials, Structures and Techniques (MBMST 2019), 2019)Various examples of glass load bearing structures such as beams, columns, panes, or even stairs are used in a current architecture. For safety reasons, these members are mostly made of laminated glass. Polymeric interlayers ... -
Research of undrained shear strength of till fine soils (moraine)
(International Conference Modern Building Materials, Structures and Techniques (MBMST 2019), 2019)The undrained soil strength is specific to fine soils or to sands with a lot of fines. It is very important characteristic and the evaluation of accurate value is significant step. The undrained soil shear strength can be ... -
Development of an anchorage prototype for CFRP stress-ribbon systems using 3D printing technique
(International Conference Modern Building Materials, Structures and Techniques (MBMST 2019), 2019)Compared with other structure types, stress-ribbon systems are extremely simple though requiring massive anchorage blocks because of very large tensile stresses induced in the ribbons. Such structural systems are efficient ... -
Concrete modular pavement type selection based on application area
(International Conference Modern Building Materials, Structures and Techniques (MBMST 2019), 2019)Roads and other trafficked areas infrastructure starts to deteriorate as far as it is opened to traffic. Thus, it has to be timely repaired and reconstructed. However, any interruption to traffic by implementing repair and ... -
The global analysis of a structure on the basis of precast building
(International Conference Modern Building Materials, Structures and Techniques (MBMST 2019), 2019)The aim of the paper is to present a global analysis of a precast, reinforced building structure. At the design stage, information about structural behaviour of particular elements and the whole structure as well as its ... -
Initial results of local strength analysis of a fiber concrete plate by 4-point bending tests
(International Conference Modern Building Materials, Structures and Techniques (MBMST 2019), 2019)The analysis of the post-cracking behavior of a large plate cast of fiber concrete shows a large variability due to the fiber alignment and dispersion. Therefore, one can expect, that the bending strength and other material ... -
Internet of Things (IoT) for digital concrete quality control (DCQC): A conceptual framework
(International Conference Modern Building Materials, Structures and Techniques (MBMST 2019), 2019)Concreting is generally a manual, labour intensive and time-consuming process, putting additional burden on constrained resources. Current practices of concreting are wasteful, non-sustainable and end products usually lack ... -
Deformations of foundations of windplant installation crane sites and their reasons
(International Conference Modern Building Materials, Structures and Techniques (MBMST 2019), 2019)Road and foundation deformations in modern Lithuanian construction are one of the most important problems. Constantly rising conflicts between customers and builders due to poor quality of foundations show that Lithuanian ... -
Numerical investigation on dynamic response of a steel lattice tower under various seismic events
(International Conference Modern Building Materials, Structures and Techniques (MBMST 2019), 2019)The present paper presents the results of the numerical study designed to investigate the soil-structure flexibility effects on modal parameters (i.e. fundamental frequencies) and time-history analysis response (represented ... -
Initial investigation of the intrinsic geomechanical properties of soils in area of landslide Černá Pole
(International Conference Modern Building Materials, Structures and Techniques (MBMST 2019), 2019)One of the most important type of Brno’s subsoil is Miocene’s clay. Mechanical properties of these clays were already studied by various methods, authors, in several locations. These parameters, however, varies across the ... -
Moment redistribution in continuous prestressed concrete box girder with corrugated steel webs
(International Conference Modern Building Materials, Structures and Techniques (MBMST 2019), 2019)A fibre-finite-element model of continuous prestressed concrete (PC) composite box girder with corrugated steel webs is established with force-based elements using OpenSees. After the model is validated with existing ... -
