Abstract Recently, microbial biopolymer-based soil treatment (BPST) has gained attention for its application in environmentally friendly stabilization, particularly enhancing the strength and stability of fine-grained soils. However, effects BPST on clay’s compressibility (consolidation) expansion (swelling) behaviors remain unclear. This study used xanthan gum, a microbially produced polysacch...

Due to the scarcity of rational models for predicting the strength of RC beam-column sandwich joints, a modified simplified softened strut-and-tie model suggests a more rational calculation method for the effective compressive strength and the height of the joint concrete based on the simplified softened strut-and-tie. The shear strength of existing tested 15 sandwich interior joints is calcula...

This paper presents a micro-mechanical study on the characteristics of shear-induced anisotropy in granular media. Based on three-dimensional Discrete Element Method (DEM) simulations, the distinct features associated with the evolution of internal granular structure and different anisotropy sources during drained/undrained shearing of granular samples are carefully examined. The study finds th...
