Glass Façade

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.

Though the technologies are dynamically developing and there are a lot of research projects, there is still no general opinion on a glass-facade building among the European scientific community, architects and construction engineers. The increasing requirements to heat-protective qualities of translucent structures make us think of the necessity of a quantum leap both in technologies and in principal approaches to the development of architectural and constructive solutions of translucent shells. Together with economical features, the dynamics of heat-protective indicators’ increase show the tendencies to reaching the possibilities limits of mass glass units. The European construction practice usually solve this problem by developing sealed insulating glass units and by different conceptual solutions of the systems of translucent double facades. In the given article the basic theoretical principles and innovative engineering ideas are formulated dealing with the modern glass-facade building construction. “Green Building” conception is analyzed as a European new building philosophy.

Glass Façade

Façade cleaning in high-rise buildings has always been considered a hazardous task when carried out by labor forces. Even though numerous studies have focused on the development of glass façade cleaning systems, the available technologies in this domain are limited and their performances are broadly affected by the frames that connect the glass panels. These frames generally act as a barrier for the glass façade cleaning robots to cross over from one glass panel to another, which leads to a performance degradation in terms of area coverage. We present a new class of façade cleaning robot with a biped mechanism that is able overcome these obstacles to maximize its area coverage. The developed robot uses active suction cups to adhere to glass walls and adopts mechanical linkage to navigate the glass surface to perform cleaning. This research addresses the design challenges in realizing the developed robot. Its control system consists of inverse kinematics, a fifth polynomial interpolation, and sequential control. Experiments were conducted in a real scenario, and the results indicate that the developed robot achieves significantly higher coverage performance by overcoming both negative and positive obstacles in a glass panel.
