Abstract Calcium sulfoaluminate (CSA) cement could be a promising alternative to ordinary Portland cement (OPC) to reduce environmental impact of concrete production. This paper investigates the performance of high performance concretes produced with CSA cement in total or partial substitution of OPC (or OPC with ground granulated blast-furnace slag (GGBS)) at water-binder ratio of 0.35. Mechanical, physical, durability, and microstructural properties of different concretes were assessed. The re...

Abstract The study investigates the mechanical response of glass shells cold bent into hyperparaboloid shapes used in building technology. Focus is addressed on two subjects: the application of the cold bending procedure to vertically oriented rather than horizontal plates, which allows to minimize the disturbance produced by the initial deflection due to self-weight, and the effect of wind load on curved glass panels installed in glazing facades. The particular case of a vertical monolithic gla...

Abstract The paper presents the results of an experimental investigation on the viscoelastic response of laminated glass joints with different interlayers. The problem is explored with double lap joints under shear loadings at temperatures between 0 °C and 60 °C. The viscoelastic mechanical parameters of a polymeric interlayer play a fundamental role in determining the response of laminated glass and thus, their knowledge is required for a fail-safe design of structural and non-structural member...

Cantilevered laminated glass plates, used e.g., in balconies and freestanding glass balustrades, are an example of the use of glass in modern architecture as a structural material. In order to fulfil its scope of preventing building occupants from failing out, the cantilevered plate must be able to transfer the loads imposed from the crowd pressure or by people in motion to the main structure of the building. Since a cantilevered plate is critical in the joint, the design of the connection betwe...

Abstract Mode I opening and mixed-mode I-II fracture experiments were performed with a homogeneous, fine grained sandstone using the three-point bending test. Specimens were notched at various lengths and positions of the beam edge to produce the desired loading condition. A micropolar peridynamic model was used to simulate the fracture initiation and propagation process. The analytical implicit formulation was derived by defining a specific microelastic energy density function for micropolar no...

For the production of a high-performance concrete (HPC) matrix, a large amount of binder is normally used. The production of ordinary Portland cement (OPC) as the binder of concrete accounts for 7% of CO2 emission, which has notable environmental impacts, and subsequently results in unsustainable concrete. The aim of the present study was to investigate the effect of replacing OPC with calcium sulfoaluminate cement (CSA) or ground granulated blast-furnace slag (GGBS) as sustainable binders on th...

Abstract The mechanical response of a plate made of a three layers laminated tempered glass (LG) with different damage configurations has been investigated and modelled by a rigid body-spring numerical approach. Experiments showed that the mechanical contribution of one or more fractured glass plies cannot be disregarded when evaluating the global stiffness of a damaged LG plate, as well as with regard to the effective stress distribution in the undamaged plies. A micro-scale analysis was perfor...

Abstract In this paper the problem of evaluation of the structural response of 1.20 m × 1.20 m blockwork masonry panels under monotonic shear and diagonal-compression tests is investigated. The digital image correlation technique was used to detect the initiation and propagation of damage. The experimental findings were analyzed and simulated also by means of accurate finite element non-linear analyses. The results revealed the non-isotropic shear response of the masonry panels, which is related...

Calcium sulfoaluminate (CSA) cement has recently gained increased attention due to its lower amount of CO2 emissions, as compared to that of the ordinary Portland cement (OPC). This paper evaluates the impact of different types of fibers on the engineering features of CSA-based concretes at different water-cement ratios of 0.35 and 0.28. In this study, metallic fibers including double hooked-end steel fibers and hooked-end steel fibers, and non-metallic fibers (i.e., polyvinyl alcohol (PVA) fibe...
