Mechanical simulation of metal perforated sheets in facades

Abstract

[EN]The aim of this study is to show an increasing tendency in modern building design. The work can be divided in three parts. First, contain information about mechanical properties of perforated metallic materials as strength and stiffness, which are based on the equivalent solid material concept. This concept is based on the evaluating the effect of the perforations and analytical results of the behavior of the solid or unperforated materials under bending and stretching. Next, is present a yield criterion for the perforated sheets with low ligament ratios. In second part is presented an experimental investigation whose purpose is to analyze the effect of perforated elements on pressure drops in a double skin cavity. Three different air flow rates and two different perforated plates are used in order to assess the experimental results. The paper is ending with the principal material used for manufacturing perforated sheets facades.
