TL;DR: In this paper, the authors adapted the mechanics of elastic composite materials to predict the basic creep of concrete with aging caused by hydration, based on the given composition of concrete, the elastic constants of the aggregate, and the aging viscoelastic properties of the portland cement mortar.

TL;DR: The addendum presents the responses to several questions on a preliminary version (which arrived too late for publication as part of the paper) as mentioned in this paper, dealing with the aircraft impact at a higher floor of the World Trade Center towers on September 11, 2001, damage to the upper part of a collapsing tower, weakness of connections, plastic cushioning of vertical impact, estimation of the equivalent mass, and the collapse of the adjacent lower building.

TL;DR: In this article, Bažant and Pang developed a new theory for the cumulative distribution function (cdf) for the strength of quasibrittle structures failing at macro-fracture initiation, and offered its simplified justification in terms of thermally activated interatomic bond breaks.

TL;DR: In this article, the size effect on the nominal strength of steel-concrete composite beams caused by shear failures of connectors such as welded studs is analyzed by two different approaches: fracture type analysis of the energy release caused by propagation of the zone of failed connectors along the beam; and a direct solution of the load-deflection diagrams from the differential equations of beam bending theory.
