TL;DR: In this article, the second-order terms associated with geometric nonlinearity were introduced into the basic equation of generalized beam theory to give rise to simple explicit equations for the load to cause buckling in individual modes under either axial load or uniform bending moment.

TL;DR: In this paper, a reinforced concrete beam section with a through-thickness edge crack in the stretched part is considered, and the eccentric axial force transmitted by the reinforcement to the concrete beam element, is estimated by means of a rotation congruence condition able to provide this statically undetermined reaction.
Abstract: A reinforced concrete beam section with a through‐thickness edge crack in the stretched part is considered. The eccentric axial force transmitted by the reinforcement to the concrete beam element, is estimated by means of a rotation congruence condition able to provide this statically undetermined reaction. In the field of linear elastic fracture mechanics, such a force increases linearly by increasing the external bending moment, until the limit force of yielding or slippage is reached. From this point on a perfectly plastic behavior of the reinforcement is considered. Once the bending moment of steel plastic flow is exceeded, the cracked beam segment presents a linear‐hardening behavior, until the concrete fracture occurs. It is shown how the stability of the process of concrete fracture and steel plastic flow depends on the mechanical and geometrical (scale included) properties of the beam cross section.

TL;DR: In this paper, six one-third scale reinforced concrete (RC) beam-column substructures, each with different design detail, span length and span aspect ratio, were designed and tested to investigate the dynamic load redistribution performance of RC substructure following predefined initial damage.

TL;DR: In this paper, exact solutions for free vibration and buckling of rectangular plates having two opposite edges (x = 0 and a) simply supported and the other two (y=0 and b) clamped, with the simply supported edges subjected to a linearly varying normal stress σx=−N0[1−α(y/b)]/h, where h is the plate thickness.
