“…The creep deformation of high-strength bolts will be significant as they are in a state of high stresses and high temperatures. Previous studies have shown that structural steels, including normal-strength steels, highstrength steels and high-strength steel wire bundles, have a great difference in material properties under fire due to different heating (transient or steady) and cooling (in air or by water) methods as well as different heat treatment processes (cold drawing or full cooling) [2,3]. The influence of creep deformation should be considered in evaluating the mechanical performance of steel connections under fire, otherwise unsafe results may be obtained [4].…”

“…The main advantage of hall buildings is the roofing of a large span without disturbing the interior layout of the building, so these buildings are suitable, for example, for the manufacturing industry, recreational facilities or for agricultural buildings. Steel is often used as the material for the construction of hall buildings [4][5][6]; however, this is disadvantageous due to its high density and low fire resistance [7,8]. In addition to the mentioned factors in the selection of construction material for hall objects, a major emphasis is also placed on the use of natural and esthetic materials [9,10].…”

Initially, timber was considered only as an easily accessible and processable material in nature; however, its excellent properties have since become better understood. During the discovery of new building materials and thanks to new technological development processes, industrial processing technologies and gradually drastically decreasing forest areas, wood has become an increasingly neglected material. Load-bearing structures are made mostly of reinforced concrete or steel elements. However, ecological changes, the obvious problems associated with environmental pollution and climate change, are drawing increasing attention to the importance of environmental awareness. These factors are attracting increased attention to wood as a building material. The increased demand for timber as a building material offers the possibility of improving its mechanical and physical properties, and so new wood-based composite materials or new joints of timber structures are being developed to ensure a better load capacity and stiffness of the structure. Therefore, this article deals with the improvement of the frame connection of the timber frame column and a diaphragm beam using mechanical fasteners. In common practice, bolts or a combination of bolts and pins are used for this type of connection. The subject of the research and its motivation was to replace these commonly used fasteners with more modern ones to shorten and simplify the assembly time and to improve the load capacity and rigidity of this type of frame connection.
