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.

TL;DR: A simple and efficient reinforcement model to consider the reinforcement slip effect is presented in this paper, which utilizes a bilinear stress-strain relationship which assumes the increase in rebar strain contributed by reinforcement slip in tensile stage.

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.

TL;DR: In this article, a numerical model considering uneven distribution of freeze-thaw damage was proposed by utilizing the results of Petersen's test for relative dynamic modulus of elasticity (RDME) for different depths of concrete sample.

TL;DR: In this article, six frost-damaged squat reinforced concrete (RC) shear walls were subjected to low cyclic reversal loading to investigate the effects of axial compression ratio, concrete strength and freeze-thaw cycles (FTCs) on the seismic performance of squat RC shear wall.
