Double-arm steel connector of glass façades

Abstract

This paper presents a numerical analysis of a steel double-arm connector, according to the authors’ solution, designed for fixation of glass façades. The analysis was carried out in order to obtain a distribution of stresses and displacements, on the basis of which global displacements and maximum stresses were determined. An additional element of the solution was the use of the M8 bolt, as a linking element of the steel walls of both arms. The numerical simulation was performed using the ADINA program, which is based on the finite element method (FEM). The dynamic effect of wind gusts on the glass façade was assumed, taking into account both wind pressure and suction. The adoption of a rectangular element of the glass façade causes an unfavorable load distribution at the connection point. The conducted research allowed to determine displacements and stresses in a steel connector made of S355JR steel. The applicability of the proposed solution for glass façades with a height of up to 100 m has been demonstrated.

Analysis of the skeleton tension structure as the load-bearing structure of a one-nave hall

“…On the other hand, in articles [5][6][7][8][9][10][11], the authors presented the methods of connections in structures, comparing various solutions to demonstrate the most effective solutions ensuring adequate load-bearing capacity. Correctly designed assembly connections ensure adequate redistribution of forces to individual load-bearing elements, while maintaining optimal cross-sections ensuring sufficient load-bearing capacity, and this allows for effective use of the load-bearing capacity of all elements in the structure [5][6][7][8][9][10][11]. Steel is characterized by high tensile strength, so it is worth using these properties in tension structures where significant loads are transferred by tensioned tendons, most often made of round steel bars.…”

Strengthening the existing connection of steel beams with a column

“…under the influence of temperature [13] as well as for various kind of connection, e.g. for connections used for fixation of glass facades [14]. The influence of high tensile bolts tightening torque on stress distribution in the bolted connection of rockfall barrier under impact load was also examined [15].…”
