Title:
Abstract:	In diesem Beitrag werden sowohl die Drucktragfähigkeiten von Labortests aus der einschlägigen Fachliteratur als auch die Ergebnisse einer numerischen Studie zum Tragverhalten von Winkelprofilen bei Druckbeanspruchung und realen Lagerungsbedingungen aufbereitet und vergleichend dargestellt. Den Schwerpunkt bilden dabei beidseits geschraubte Ausführungsformen. Die präsentierten Drucktragfähigkeiten werden außerdem mit den gültigen Normenregelungen für den Freileitungsbau sowie für den allgemeinen Stahlbau (Hochbau) verglichen. Das ausgearbeitete Beispiel am Ende des Beitrags ergänzt den Vergleich und kann als Hilfestellung für die Praxis dienen. Load bearing capacity of angle profiles under compression with realistic boundary conditions. In this paper the compression capacities of tests in literature are compared with results of a numerical study considering realistic boundary conditions. The main focus is on compression members with bolted connections on both ends. The presented compression capacities are also compared with design rules of different codes for transmission towers and steel structures (buildings). At the end of the article, an example shows the suggested design procedure in practice.
