TL;DR: In this paper, a laboratory-scale model of RFC consisting of coarse aggregates and cement grout was cast to simulate RFC in construction, and the effects of different factors (aggregate size, rheology of cement grouts, etc.) on the properties of the interfacial transition zone (ITZ) between cement paste and aggregates of model RFC were investigated using Backscatter Electron (BSE) and nanoindentation techniques.

TL;DR: In this article, three different fracture procedures were compared for the three-dimensional seismic cracking analysis of gravity and arch dams during strong earthquakes, including the extended finite element method with cohesive constitutive relations, crack band finite elements method with plastic-damage relations, and the finite element Drucker−Prager elasto-plastic model.

TL;DR: In this paper, a new family of explicit integration algorithms based on discrete control theory for solving the dynamic equations of motion is developed, which are explicit for both displacement and velocity and require no factorization of the damping matrix and the stiffness matrix.

TL;DR: In this article, a mix design method for self-compacting concrete (SCC) based on its paste rheological characteristics was developed, which yielded practical benefits by saving on the amount of laboratory work, testing time, and raw materials.

TL;DR: In this article, a three-dimensional finite element program for thermal analysis of mass concrete embedded with double-layer staggered heterogeneous cooling water pipes was developed based on the equivalent equation of heat conduction including the effect of cooling water pipe and hydration heat of concrete.
