Residual Fatigue Life Assessment of Damaged RC Bridge Slabs Based on Site-Inspection for Cracking: A Quantitative Discussion
TL;DR: In this article, a pseudo-cracking approach is presented to estimate the residual fatigue life of bridge slabs under expected future loads, where the past traffic loads' record is not available in most cases.

Shear transfer constitutive model for pre-cracked RC plate subjected to combined axial and shear stress
TL;DR: In this paper, the authors proposed a constitutive model for the shear transfer through the cracks of pre-cracked reinforced concrete (RC) plate subjected to combined axial and shear stress.

Deformational compatibility for solid phase of dense liquid-solid flow in bend pipes
TL;DR: In this article, the authors established the deformational compatibility for aggregate phase of concrete in bend pipes used for concrete pumping, which describes the relationship between the strain rate of aggregate phase (particle assembly) developing over a reference section and sectional mean flow speed of the particle assembly, is essential in one-dimensional computation of dense liquid-solid flow in pipe lines.

Model-Based Assessment of Long-Term Serviceability and Fire Resistance for Underground Reinforced Concrete Ducts
TL;DR: In this article, the collapse simulation of underground reinforced concrete (RC) ducts surrounded by soil foundations in a fire was conducted using multi-scale finite element analysis, and the underground RC ducts are f...
