Nonlinear long-term behaviour of spherical shallow thin-walled concrete shells of revolution

Abstract: a b s t r a c tThe nonlinear long-term buckling behaviour (creep buckling) of spherical shallow, thin-walled concrete shells of revolution (including domes) subjected to sustained loads is investigated herein. A thorough understanding of their nonlinear time-dependent behaviour, as well as the development of comprehensive analytical models for their analysis, has hitherto not been fully established and further studies are required. A nonlinear axisymmetric theoretical model, which accounts for the effects of c… Show more

“…In addition to geometrical imperfections, material properties and changes over time add another dimension to the buckling analysis of concrete caps (Hamed, Bradford and Gilbert, 2010;Dulácska, 1985). The reduction factor on the classical elastic buckling load in real shells is significant, with reported reductions of up to 96% in capacity (Kenaway, 2014).…”

“…From the viewpoint of long-term structural integrity, the creep buckling is one of the important failure modes of thin-walled concrete shell structures, which are widely used in large-scale civil engineering structures. Hamed et al (2010aHamed et al ( , 2010bHamed et al ( , 2011 performed the creep buckling analysis of a thin-walled shallow partial-spherical concrete dome subjected to a uniformly distributed perpendicular pressure and its self-weight. In their analysis, they considered the effects of creep and shrinkage via integral-history-type constitutive relations (Bazant, 1988;Gilbert, 1988) based on the principle of superposition.…”

“…They derived the nonlinear governing field equations along with the boundary conditions from a variational principle and solved them using the multiple shooting numerical method (Stoer and Bulirsch, 2002). The critical time of axisymmetric snap-through buckling during creep deformation was defined using the quasi-static method as the time when dW c /dt (W c : central deflection of a spherical shell, t: time) (Hamed et al, 2010a), although it should be determined by the energy method. Hamed et al (2010b) obtained the bifurcation mode of creep buckling using the load-disturbance method, a numerical method for the advanced postbuckling analysis of elastic shells of revolution proposed by Teng and Hond (2006), and examined the effects of various imperfections on the creep buckling of a thin-walled shallow partial-spherical concrete dome.…”
