Stabilitätsverhalten von schlanken Wandscheiben aus Normal- und Ultrahochleistungsbeton

Load bearing behavior and stability of slender wall panels made of normal strength and ultra-high performance concrete.

Following more than one decade of theoretical and experimental research on ultra-high performance concrete (UHPC) today there is a series of possible applications to efficiently utilize this new and innovative material in load-bearing structures. One example are walls and wall panels respectively, the thickness of which may be decisively reduced thanks to the high compressive strength, leading to increasingly slender structures being more sensitive in terms of stability. The present paper describes theoretical and experimental investigations on the load-bearing and buckling behavior of normal strength and UHPC wall panels being currently performed at the chair of concrete and masonry structures of TUM. In doing so, exemplary results of these investigations are presented and discussed and an engineering model determining critical loads of slender walls is derived.
