Engineering Characteristics and Reinforcement Approaches of Organic Sandy Soil by Jun Hu, Liang Jia, Wei Wang, Hong Wei, Juan Du

“…As the unconfined compressive strength of the cement-admixed organic sandy soil was much lower than that of ordinary sand, some innovative ground improvement technologies were proposed for stabilizing organic sandy soil, such as thermal pile, fiber, and steel-, bamboo-, and freezing-cemented soil columns. The main purpose of these technologies is to enhance the bearing capacity of organic sandy soil but reduce the usage of cement, as the latter is not an eco-friendly material.…”

Structural restoration of a historic palace in Italy by Paolo Foraboschi

“…One of the key novelties of this study is the introduction of a method for designing and structurally analyzing a rehabilitation work aimed at enhancing the load-bearing capacity of masonry columns and piers under gravitational loads. The discussion also emphasizes the often-overlooked limitations of material testing in accurately assessing masonry strength and delves into the critical impact of material and geometric nonlinearities on maximum stress levels – issues that remain underexplored in the existing literature.…”

Prediction of buckling damage of steel equal angle structural members using hybrid machine learning techniques by Nang Xuan Ho, Tien-Thinh Le, The-Hung Dinh, Van-Hai Nguyen

“…For this purpose, a database concerning compression tests of steel equal angle structural members was constructed from available resources with geometry variables such as length, width, thickness, mechanical properties of materials such as yield strength and initial imperfections (i.e. residual peak stress and initial geometric imperfections) and critical buckling load of columns. The hybrid PSOANN model was adopted because its prediction capability is higher than the traditional technique – i.e. scaled conjugate gradient (SCG). …”
