Column shortening of concrete cores and composite columns in a tall building

The Structural Design of Tall and Special Buildings, 2005
The effect of column shortening is a major consideration in the design and construction of tall buildings, especially in concrete and composite structural systems. The method presented in the PCA report is the most widely used for the analysis of column shortening, but results can be very different depending on the time function of shrinkage suggested ...

COMPOSITION ESTIMATORS FOR A DISTILLATION COLUMN: THEORY AND EXPERIMENTS

IFAC Proceedings Volumes, 1995
Abstract This work is a contribution to the development of non-linear estimators based on the Extended Kalman Filter theory to monitor the dynamics of a continuous distillation column. The performances of the estimators are checked by comparison with the behavior of a pilot distillation unit where fractionations of ethanol-water binary mixtures are ...

Elastic Stability of Composite Column

Journal of Engineering Mechanics, 1992
A vertical column possessing two different flexural rigidities is clamped at the bottom end and is free at the top. Both piecewise uniformly distributed axial loads (self-weights) and a concentrated load at the top are applied to the column. For the buckling load, the governing differential equation is a second-order nonlinear with variable ...

Buckling of cracked composite columns

International Journal of Solids and Structures, 1990
Abstract A crack in a structural element introduces a significant local flexibility which enhances the instability. Buckling of an edge-notched beam is studied for isotropic and anisotropic composites. The local compliance due to the presence of cracks in an anisotropic medium is formulated as a function of the crack-tip stress intensity factors and ...

Ductility of encased composite columns

This paper presents results ofanumerical study onreinforced concrete and fully encased composite columns designed according to the “Inerd” concept aiming at obviating the soft storey mechanism in frames subjected to earthquake. The model uses fibre beam elements with mono-axial non linear material laws for concrete, steel and reinforcing steel.
