Linear Local Buckling of Thin UHPC Walls without Intermediate Stiffeners

Popis výsledku v původním jazyce

Modern cementitious composites, such as UHPC, enable the construction of increasingly more slender elements with thin-walled cross sections resembling the proportions typical for steel structures. However, such members are subjected to the problem of loss of stability of individual walls. This problem has historically received little attention in the field of concrete structures. Therefore, this paper deals with one of the basic types of stability loss of thin-walled elements – local buckling. The critical stress values of variable length internal and outstanding walls, subjected to compression, bending, or shear loads assuming a linear elastic material response and zero imperfections, are determined by numerical analysis. For the lowest values of critical stress, criteria for the maximum admissible slenderness of UHPC walls are obtained, and finally the paper concludes with the minimum admissible thicknesses required to ensure stable behavior for a wall with reference dimensions.
