Abstract Strenx 700 is a high-strength structural steel with a minimum yield strength of 650–700 MPa (94–102 ksi) depending on thickness. Strenx 700 meets the requirements of EN 10 025-6 for the S690 grade and thicknesses. Typical applications include demanding load-bearing structures. This datasheet provides information on composition, physical properties, and tensile properties as well as fracture toughness. It also includes information on surface qualities as well as forming, machining, and joining. Filing Code: SA-779. Producer or source: SSAB Swedish Steel Inc..

The article describes experimental research of bending rubber fiber concrete elements with favorable deformation-strength characteristics. The use of such a material as fiberrubcon in load-bearing structures due to its high strength leads to a decrease in material consumption and weight of structures.

First Results

<p>Timber is one of the few renewable materials that improves its structural properties when combined with concrete. The composite of timber and concrete increase stiffness and fire protection, unlike timber when used alone. In contrast to concrete structures, timber-concrete composite (TCC) structures reduce the carbon footprint and the specific weight of a building. At the Chair of Hybrid Structures - Structural Concrete of BTU Cottbus-Senftenberg a moment-resistant TCC joint was developed for multi-story frames, which can be used as a structural system for high-rise buildings. Facts like a modular construction, a fast assembly and a plug-in connection were aspects that shaped the development. A high rotational stiffness and load-bearing at the composite joint was also achieved using high strength beech laminated veneer lumber (LVL).</p><p>The TCC frame works on its own and in combination with other bracing systems. Initial investigations on the load-bearing behavior were carried out using numerical analysis followed by experiments on real-sized joints in further studies. First results will be presented in this paper. The developed TCC joint as part of structural systems offers a high variability and can thus contribute to tomorrow’s sustainable vertical growth of cities.</p>

The Impact

The use of high strength concrete (HSC) in multi-story buildings has become increasingly popular. Selection of HSC over normal strength concrete (NSC) allows for reducing the dimensions of the columns sections. However, this reduction has consequences on the structural performance in case of fire, as smaller cross sections lead to faster temperature increase in the section core. Besides, HSC experiences higher rates of strength loss with temperature and a higher susceptibility to spalling than NSC. The fire performance of a column can thus be affected by selecting HSC over NSC. This research performs a comparison of the fire performance of HSC and NSC columns, based on numerical simulations by finite element method. The thermal and structural analyses of the columns are conducted with the software SAFIR®. The variation of concrete strength with temperature for the different concrete classes is adopted from Eurocode. Different configurations are compared, including columns with the same load bearing capacity and columns with the same cross section. The relative loss of load bearing capacity during the fire is found to be more pronounced for HSC columns than for NSC columns. The impact on fire resistance rating is discussed. These results suggest that consideration of fire loading limits the opportunities for use of HSC, especially when the objective is to reduce the dimensions of the columns sections.

High Strength Fiber

Ukraine's construction heritage includes numerous examples of the use of metal structures, especially those used in industrial buildings and high-span structures. The use of metal structures in construction is due primarily to their mechanical properties. They are frost-resistant and can withstand temperatures down to -65 degrees, hard, durable, strong and reliable. They can also be used in areas with high seismic activity. But, as in the case of other types of structures, there is a need to restore or strengthen metal structures due to structural defects, wear of load-bearing elements, as well as to increase the load-bearing capacity. In some cases, reinforcement with fiber-reinforced polymer composites (FRP) gives a better result compared to traditional methods of reinforcement using metal
