CFT columns filled with normal strength concrete and subjected to concentric axial loads 1 INTRODUCTION The use of concrete filled tubular (CFT) columns has increased in recent decades due to their excellent structural performance which takes advantage of the combined effect of steel and concrete working together

The primary objective of this project is to establish the seismic performance factors for elevated liquid tanks In addition the nonlinear dynamic response behaviour of supporting towers in elevated liquid tanks when subjected to extreme dynamic loads will be investigated A numerical approach which employs finite element technique as well as a probabilistic collapse analysis method is proposed

It is known that the bond strength between both steel and FRP reinforcing tendons and concrete deteriorates at elevated temperature and that high strength concrete tends to an explosive spalling failure mode when subjected to a fire The bond strength reductions in fire their impacts on the load-bearing capacity of prestressed concrete structures and the spalling behaviour of high-strength

concrete mixtures prepared by ordinary Portland cement crushed limestone and river gravel Test samples were subjected to elevated temperatures ranging from 200 to 1200C After exposure weight losses were determined and then compressive strength test was conducted Test results indicated that weight of the specimen significantly reduced with an increase in temperature This reduction

Creep is more severe in materials that are subjected to heat for long periods and generally increases as they near their melting point The rate of deformation is a function of the material's properties exposure time exposure temperature and the applied structural load Depending on the magnitude of the applied stress and its duration the deformation may become so large that a component can

Within the European RFCS ROBUSTFIRE project the behaviour of steel and composite car parks subjected to localised fire leading to a column loss was investigated Under such a scenario the beam-to-column joints play a key role in the global structural response Indeed these joints initially loaded in bending may be subjected to elevated temperatures and to combined axial load "N" and

TIME-DEPENDENT FIBRE PULL-OUT BEHAVIOUR IN SELF-COMPACTING CONCRETE Amin Abrishambaf *1 was obtained [5 6 9] To the authors' best knowledge only a limited number of studies are dedicated to time-dependent fibre pull-out behaviour In the works of Babafemi et al and Boshoff et al [11 12] aligned synthetic fibres (i e fibres perpendicular to the crack plane) were pulled-out just
