Abstract: Although there are numerous experimental studies of the size effect on nominal splitting tensile strength of concrete materials being performed, research on effect of specific material parameters involving maximum aggregate ...

Abstract: Sand typically exhibits anisotropic internal structure (or fabric), and the fabric anisotropy has a dramatic influence on the mechanical behavior of sand. Meanwhile, the fabric evolves when sand is subjected to external ...

Abstract: The complexity of the pairwise comparison process in the analytic hierarchy process (AHP) and the limitation of consistency are challenges that need to be addressed when there are many evaluation factors. An improved AHP ...

Abstract: Earthquake-induced damage often is caused by large deformation and floor acceleration. To ensure a fast function recovery process, controlling postevent permanent deformation also is very critical. Combining the merits of ...

Abstract: Fly ash (FA), silica fume (SF), and ground blast furnace slag (GBFS) were used as the supplementary cementitious materials (SCMs) in cement paste. The autogenous shrinkage (AS) and the shrinkage cracks of cement paste with ...

Abstract: In order to study the effect of different structural parameters on the connection performances of a tapered head sleeve (THS) and the calculation method of the bond strength, a three-dimensional finite-element model was ...

Abstract: An accurate and efficient numerical model is developed to calculate the earthquake-induced hydrodynamic pressure on uniform vertical cylinders with an arbitrary cross section surrounded by water. According to the boundary ...

Abstract: Most previous studies have made great progress in the size effect of concrete materials and several classic size effect laws (SELs) have been proposed. However, there is a lack of size effect laws for RC components including ...

Abstract: Bridges may suffer large residual displacements after strong earthquakes. These large residual displacements may increase the reinforcement cost and even lead to the collapse of the bridge. Various self-centering energy ...

Abstract: Concrete structures often suffer from multiple dynamic loads, or prior to being subjected to dynamic loads have already withstood initial loads. The mechanical properties of concrete materials under dynamic loads may be ...
