Abstract
With the development of wooden structures and buildings, there is a need to research physical and numerical tests of wood-based structures. The presented research is focused on construction and computational approaches for new types of joints to use in wooden structures, particularly glued lamella elements made of wood and wood-based composites. This article focuses on improving the frame connection of a wooden post and a beam with the use of fasteners to ensure better load-bearing capacity and stiffness of the structure. In common practice, bolts or a combination of bolts and pins are used for this type of connection. The aim is to replace these commonly used fasteners with modern ones, namely full thread screws. The aim is also to shorten and simplify the assembly time in order to improve the load-bearing capacity and rigidity of this type of frame connection. Two variations of the experimental test were tested in this research. The first contained bolts and pins as connecting means and the second contained the connecting means of a full threaded screw. Each experiment contained a total of two tests. For a detailed study of the problem, we used a 2D or 3D computational model that models individual components, including fasteners.

Summary
Wood is an important building material that can be used in all applications of construction tasks. It is possible to use specific dynamic testing [3] or the vibration acoustic method [4]. The current possibilities of wood processing technology and design of structures allow a wide range of applications from simple structures, through multi-story buildings [6] to long-span structures [7]. It is important to take into account the experience from previous accidents and structural failures in design and analysis [8]. For a correct understanding of the behavior and design of wooden structures, it is appropriate to use experimental tests of structural details [9,10,11] or structural parts, such as entire frames [12]. In particular, frame corner [16], timber-to-timber joints [17], connection/joint [18], and detail [19] experiments
