Bond-slip model considering freeze-thaw damage effect of concrete and its application
TL;DR: In this paper, a novel bond-slip model considering freeze-thaw damage effect of concrete and applying it into the fiber model was developed by modifying an existing bond-sink model to consider the freeze-thyaw damage of the concrete.

Multi-scale simulation of freeze-thaw damage to RC column and its restoring force characteristics
Fuyuan Gong,Koichi Maekawa +1 more
TL;DR: In this article, an integrated life-time simulation of reinforced concrete (RC) columns is presented, which starts from micro-pore formation and follows micro-scale frost action to the non-uniform frost damage considering temperature distributions, arrangement of reinforcing bars as well as the water uptake from the boundary, and finally to structural mechanical performances such as capacity and ductility.

Experimental study on the seismic behavior of RC shear walls after freeze-thaw damage
TL;DR: In this paper, the authors used the artificial climate rapid freeze-thaw technique to simulate the freezethaw environment to investigate the seismic performance of reinforced concrete (RC) shear walls, and the results indicated that the flexural-shear failure of the RC shear wall shifts from a flexuredominated mode to a sheardominated one.
